Texte intégralMangroves are environments so rich in biodiversity which functionality made by nutrient cycling. The main vegetable specie is Rhizophora mangle. This study objected to know bacterial endoglucolytic diversity and tolerance saline of rhizobacteria associated to R. mangle. Plants from Bertioga (oil contaminated) and Cananéia (not polluted) were sampled. From both sites, 129 bacteria were isolated, which most diversity observed from Cananéia. These isolates, 30 presented endoglucolytic activity and Bacillus subtilis (strain 39a) was characterized as top producer. The presence of EglA gene was confirmed using specific primers. The salinity test showed halotolerance, mainly strain 39a that growth untill about 20% NaCl. The scan electron microscopy of strains allowed biofilm production at elevated salinity that suggest the biofilm as tolerance mechanism to saline environment. The results indicated that ecosystem preservation makes a most diversity bacterial environment and that Bacillus spp. are main endoglucanase producer and response to saline stress producing biofilm.

Texte intégralMangroves are ecosystems of great ecological and economical importance. Considering that these areas have been degradated, specially by deposition of solid wastes and liquid effluents containing heavy metals it becomes important to identify to what level these contaminants interfere on the development of plants that colonize such environs. Therefore, the aim of this study is assess the effects of heavy metals on the development of propágulos, plântulas and mudas of the Mangue vermelho (Rhizophora mangle), specie which is widely spread on mangroves, in order to determine environmental quality at the mangrove. Three study areas with considerable degradation were selected in the municipalities of Cubatão and São Vicente, in the Baixada Santista - SP, industrial coastal region and greatest sea port of Brazil and a background non contaminated area located on the Cardoso Island and in Cananéia. Due to the absence of a metal concentration standard for plants, environmental quality was assessed by comparison between five different metals determined in the soil, water, vegetation and organisms at the selected sites. Worst environmental conditions were found at the Cosipa Channel, intermediate at the Cascalho river and best at Mariana river. It was verified that metal concentration was associated with mangrove development (altered as a function of degradation level), being this a cause for the decreased establishment of R.mangle at the Baixada Santista area.

Texte intégralMangroves are considered a coastal ecosystem, located in the transition between the terrestrial and marine environments. This environment is typical of tropical and subtropical regions and is found throughout the world, mainly in Brazil, Indonesia and Australia. The occurrence of a large amount of organic matter enhances the fact that microorganisms are important in the cycling of nutrients in these environments. Endophytic microorganisms can be extremely relevant to the plant existing in mangrove swamps, because live in the interior of these, in its entire life cycle or only part of it, not harm him or cause any apparent damage to it. The endophytic can give to your host important characteristics such as greater resistance to conditions of stress, supply of nutrients and other components of biotechnological interest (such as enzymes, antibiotics and drugs of pharmaceutical interest). This paper therefore finds the diversity of endophytic diazotrophic bacteria exist in red mangrove (Rhizophora mangle) of Ilha do Cardoso (Cananéia - SP) and study the functional biodiversity of the main groups and potential biotechnology.

Texte intégralThis study aimed to establish a citogenotoxic method, the comet assay, adapted to the meristematic cells from propagule roots of red mangrove, Rhizophora mangle, for use in studies of genotoxicity in marine environments. Experiments were carried out to test two ways of root germination, four different nuclei extraction solutions, two lysis solutions and without lysis, two periods of exposure to lysis, two periods of unwinding, two periods of electrophoresis and the interaction of two lysis conditions with two different times of unwinding. Experiments on validation of the method were performed by exposing the nuclei to four different concentrations of hydrogen peroxide. The results showed that it is possible to obtain comets with nuclei extracted from the root of propagules of Rhizophora mangle and the validation data showed a dose-dependent relationship between the damage index and the concentration of the genotoxic agent tested. The best parameters to obtain comets using the method adapted by us are: PBS or saline 12‰ as extraction solution, exposure to alkaline lysis for 60 minutes, 5 minutes of unwinding and electrophoresis in buffer pH> 13, 0,8V/cm, 230mA for 20 min at 4ºC.

Rhizophora mangle L. é a espécie arbórea mais frequente no mangue brasileiro e tem intenso uso popular no tratamento de doenças mucocutâneas. A fim de fornecer base científica para sua utilização, este estudo teve por objetivos avaliar a atividade cicatrizante de creme de extrato aquoso de folha de Rhizophora mangle L. em ratos Wistar, e investigar a ação citotóxica e o perfil fitoquímico dos extratos aquosos das folhas, caule e raiz de R. mangle. O screening fitoquímico dos extratos aquosos de folhas, caule e raiz da planta foi realizado a partir da identificação dos compostos majoritários. Realizou-se a investigação da citotoxicidade dos extratos das três partes da planta, com concentrações de 100; 10; 1; 0,1; 0,01; 0,001; 0,0001 e 0,00001 μg/mL frente as células Hela (104 células/mL), e como controle utilizou-se o Dimetilsufóxido (0,1%). Para avaliação da atividade cicatrizante do creme de extrato aquoso foram utilizados 45 ratos Wistar, fêmeas, submetidos à indução de ferida cirúrgica e divididos em 3 grupos (controle negativo, padrão e tratado). Cada grupo recebeu, respectivamente, aplicação de soro fisiológico a 0,9%, dexpantenol a 5% em creme e extrato aquoso da folha da R. mangle. a 5% em creme, e foram acompanhado até o 5o, 10o e 15o dia de pós-operatório para avaliação dos aspectos macroscópicos das feridas e avaliações morfométrica e histomorfométrica. O grupo tratado apresentou feridas uniformes e sem infecção, quando comparado aos outros dois grupos, porém a análise morfométrica não mostrou no 15o dia diferença estatística entre os grupos devido ao formato retangular da ferida inicial. O estudo histomorfométrico demonstrou que todos os animais tratados com o creme de R. mangle apresentaram reepitelização completa no 15o dia de pós-operatório (0,00 ± 0,00) em relação ao padrão (1.26 ± 0.77) e controle negativo (2.45 ± 0.62). Houve proliferação de células Hela sob ação das diferentes concentrações de 0,001 a 100 μg/mL nos extratos das folhas e caule, e na raiz em 100 μg/mL com p>0,05. O perfil fitoquímico revelou presença de taninos nos três extratos, além de flavonóides na folha; flavonóides, triterpenos e saponinas no caule, e na raiz revelou também a presença de triterpenos. Através de ensaios fitoquímicos ficou comprovado a presença de taninos, flavonóides, triterpenos e saponinas nos extratos aquosos de R. mangle e foi também observado efeito mitogênico em células HeLa. Este estudo revelou que o uso tópico do EAF. R. mangle a 5% em creme apresenta efeito significativo na reepitelização de feridas cirúrgicas em ratos e reforçou a importância da realização da histomorfometria na correlação com os achados morfométricos.
Rhizophora mangle L. is the most common species in Brazilian mangrove and has intense popular use in treatment of mucocutaneous disease. In order to provide scientific basis for its use, this study aimed to evaluate the healing activity of aqueous extract cream of Rhizophora mangle L. leaves in rats, and to investigate the cytotoxic activity and phytochemical screening of aqueous extracts of leaves, stem and root of R. mangle. Phytochemical screening of aqueous extracts of leaves, stem and root of the plant was done by identification of major compounds. The cytotoxicity of the extracts of the three parts of the plant, with concentrations of 100; 10; 1; 0.1; 0.01; 0.001; 0.0001 and 0.00001 ug / mL was evaluated on Hela cells (104 cells / ml) and dimethylsulfoxide (0.1%) was used as control. To evaluate the healing activity of aqueous extract cream were used 45 Wistar rats, females undergoing induction wound and divided into 3 groups (negative control, standard and treated). Each group received respectively 0.9% saline, 5% dexpanthenol in cream and 5% aqueous extracts of leaves of R. mangle in cream, for a period of 5th, 10th and 15th day postoperatively to evaluate the macroscopic aspects of the wounds and morphometric and histomorphometric evaluations. The treated group showed uniform wounds without infection when compared to the other two groups, but the morphometric analysis did not show on the 15th day statistical difference between the groups due to the rectangular shape of the original wound. The histomorphometric study showed complete epithelialization of the animals treated with R. mangle cream on the 15th day after surgery (0,00 ± 0,00) compared to the standard (1.26 ± 0.77) and negative control (2.45 ± 0.62). There was proliferation of Hela cells different concentrations from 0.001 to 100 mg/mL of the extract of leaves and stem, and 100 mg / ml of root with p> 0.05. The phytochemical profile revealed the presence of tannins in the three extracts, and flavonoid in leaves; flavonoids, saponins, triterpenes in stem, and in root was also revealed the presence of triterpenes. Through phytochemical assays it was proven the presence of tannins, flavonoids, triterpenes and saponins in aqueous extracts of R. mangle and mitogenic effect was also observed in HeLa cells. This study showed that th topical use of aqueous extract of leaves of R. mangle in cream at 5% has significant effect on epithelialization of surgical wounds in rats and reinforced the importance of holding the histomorphometry in correlation with the morphometric findings.

Texte intégralAlthough with little attention by academics, the onomatopoeia are an integral part in the comics language, especially on mangas (Japanese comics). With the increasing publication of mangas in Brazil, it makes us realize that there are several obstacles in translating them, and the onomatopoeia are one of them mainly by the presence of the mimesis Gitaigo, words that expresses psychological and emotional aspects, but behaves like onomatopoeias in Japanese language. Thus, this study sought to identify and analyze the translations/adaptations of Japanese onomatopoeia and mimesis in manga translated to Portuguese. Thinking in situations closer to the Brazilian readers dayly life (which would facilitate the understanding of the usage and function of onomatopoeia/mimesis) we choose publications aimed at the female readers, the Shojo manga. Based on theories of translation strategies, we identified eight cases most used in Brazilian translations of manga.

Texte intégralBrazil is one of the largest producers of tropical fruit in the world, with a production of more than 31 million tones. However, in spite of its large capacity, Brazil runs a trade deficit in fresh fruit. First, this research identifies the factors relevant to the exportation of fruit in the areas of production, processing, distribution, commercialization and consumption with the objective of understanding better the supply chain management of fruit growing for the foreign market. Some of the factors which considered are the operational stages of the international supply chain of Brazilian mango (foreign trade and logistics), operational peculiarities, the safety and quality of the mango, the best practices of fruit suppliers of the international market and the factors limiting the export of Brazilian mango to the principal international markets. After identification and analysis of the relevant factors, the focus becomes specifically the mango chain and, based on strategy and supply chain management theory, a model is proposed to guide the choice of management strategy of the supply chain of Brazilian mango for the foreign market. The model which is proposed takes into account the competitive strategy of the firm and the supply chain strategy to obtain the best alignment of the two for serving coherently the expectations of the target-market.

No Japão, há diversas manifestações estéticas que ainda refletem o espírito de sua tradição milenar, que provém da filosofia Zen-budista. O Mangá, denominação dada às histórias em quadrinhos japonesas, teve como uma de suas primeiras expressões pergaminhos desenhados pelo monge Toba (século XI). Atualmente, os mangás consistem na maior indústria editorial de histórias em quadrinhos do mundo. Há no mercado uma gama enorme de mangás publicados em Língua Portuguesa, os quais têm uma grande repercussão no Brasil, principalmente entre o público jovem. Nesse trabalho, toma-se o mangá como uma forma de expressão humana e, por consequência, um ato de comunicação. Essa dissertação busca, ao analisar os dois primeiros volumes da publicação brasileira da série Neon Genesis Evangelion, verificar se esse mangá possui um caráter estético que o permita transcender a situação de mera produção mercadológica.

O manguezal é um ecossistema tropical das regiões litorâneas e estuarinas, importante como abrigo e local de reprodução de animais marinhos e para o aumento da produtividade de comunidades vizinhas. Sua vegetação, o mangue, é composta por poucas espécies com características peculiares, tais como viviparidade e raízes relacionadas às trocas gasosas. Há poucos estudos que abordam os padrões fenológicos e os sistemas de polinização e reprodução das espécies de mangue, sendo fundamentais para manejo e conservação desse ecossistema. Portanto, nesta Tese, análises sobre esses aspectos foram feitas em uma área de manguezal em Pernambuco, Nordeste do Brasil, para melhor compreensão da dinâmica de comunidade. A fenologia reprodutiva das quatro espécies de mangue ocorrentes na área, Avicennia schuaeriana (Acanthaceae), Conocarpus erectus, Laguncularia racemosa (Combretaceae) e Rhizophora mangle (Rhizophoraceae) foi acompanhada mensalmente durante quatro anos. Os sistemas de polinização e reprodução também foram investigados para cada espécie. A floração na comunidade seguiu um padrão contínuo bimodal, com picos nas duas estações, seca e chuvosa. A frutificação também foi contínua, porém sazonal unimodal, com pico na estação chuvosa. Rhizophora mangle é anemófila, apresentando padrões de floração e de frutificação contínuos. As outras três espécies possuem sistema de polinização generalista, sendo visitadas pelos mesmos grupos de polinizadores, abelhas, borboletas, moscas e vespas, sendo a mosca Palpada albifrons a principal polinizadora das três espécies entomófilas. A floração dessas espécies é seqüenciada ao longo do ano, havendo sobreposição, porém, com picos em épocas distintas, possibilitando a permanência dos polinizadores na comunidade e favorecendo o sucesso reprodutivo por meio da facilitação. Todas as espécies de mangue foram autocompatíveis, sendo a maioria autógama, com exceção de A. schaueriana. Contudo, a maior formação de frutos ocorreu sob condições naturais em todas as espécies de mangue, mostrando a importância dos vetores de polinização, seja abiótico ou biótico. Apesar da autocompatibilidade, cada espécie apresentou uma estratégia reprodutiva que favorece a polinização cruzada e conseqüentemente a manutenção da variabilidade genética na população, tais como protandria em A. schaueriana e R. mangle, ginodioicia em L. racemosa e andromonoicia associada à protoginia em C. erectus

Texte intégralThe research presented here is focused in the cultural movement known as Movimento Mangue or Manguebeat, which appeared in the Brazilian city of Recife in the 1990’s. More specifically, the works of the two most important in the movement bands is studied: Chico Science & Nação Zumbi and Nação Zumbi. Through its description and study, it is wished to verify if it is possible to characterize Manguebeat as an Avant-garde movement. In order to achieve that objective, we will analyze the studies of Guillermo de Torre, Peter Bürger, Gonzalo Aguilar, Antonio Candido, Ferreira Gullar, and other critics, searching for a definition to the concept of Avant-garde. Afterwards, we will trace in which ways the concepts raised will guide the analysis of the thesis. Hereafter, a possible existence of two sides inside Manguebeat will be verified: one represented by Chico Science & Nação Zumbi and Nação Zumbi and their concept of Mangue; and another one that groups the other artists that took part in the movement. By making this distinction, it will be possible to understand the differences between the work of the two first bands cited and that of the other artists that also joined the movement. It is observed observed that Chico Science & Nação Zumbi and Nação Zumbi concentrate in their songs an Avant-garde ideal quite relevant, especially in what concerns the rejection of what is particular, following the notion of Guillermo de Torre. A corpus will then be organized, formed by songs of these two bands, in order to verify which Avant-garde characteristics found in the studies of the theme would be present in their works. It is also our intention to show some aspects and more relevant works among those that are part of the second group of artists: those who took part in the movement, but only sharing with the first two the notion of creative freedom, and not the whole concept of Mangue. It is intended then to determine whether both the works of Chico Science & Nação Zumbi and Nação Zumbi and Manguebeat as a whole can be considered Avant-garde, thanks to, among other aspects, the break they bring to their cultural context.

Texte intégralThe purpose of the present study was to verify and compare the chemical and physical-chemical behaviour of mango cv. Tommy Atkins subjected to hydrothermal treatment and irradiation at doses 0.4 and 1.0 kGy, to complement the studies by SABATO et al (2009) in the real transport of irradiated mangoes from Brazil to Canada. These studies allowed to compare the performance of irradiation with heat treatment on the preservation of the characteristics of mango for export. For these reason fruits were divided into groups: control, heat bath (46 ° C for 90 min), at dose 0.4 kGy and at dose 1.0 kGy. The fruits were stored at low temperature (11 ° C ± 2) for 14 days, and then at room temperature (23 ° C ± 2) until the end of its useful life. During the period of cold storage the analysis were performed at intervals of 7 days and every 3 days when kept at room temperature. The results indicated that the dose of 1.0 kGy was the only group that kept the fruit with the skin color on stage 3 throughout the experimental period, but provided a greater loss of texture degradation and the levels of total acidity in the fruits with green skin. It was noted that only the control group showed higher levels of citric acid and succinic acid in the last day of the experiment. There were no significant differences in soluble solids, total sugars and evaluation of weight in relation to treatments. The analysis of visual observation indicated that the heat bath group was the one with the highest number of fruit drop by decomposition with approximately 55%. It was concluded that irradiation is more effective in preserving the quality of mangoes cv. Tommy Atkins, reducing the appearance of rot or shriveling in relation to heat treatment. However, the preservation of the skin of fruit is not concurrently influenced by its intrinsic nature, since, internally, the fruits continue their normal maturation, independent of the applied dose.

Abstract: The purpose of the present work was to study the effect of hyperbaric atmospheres in the postharvest conservation of 'Palmer' mango. The experiments were carried out in the Post-Harvest Laboratory of FCAV-UNESP, Jaboticabal Campus. Palmer' mangoes were used at the stage of physiological maturation, from orchards of the Ogata Citrus Company, in the city of Taquaritinga-SP. In the first stage the treatments consisted in placing the fruits in hyperbaric chambers and applying five pressure levels (1, 2, 4, 6 and 8 atm) at 22 ± 1 °C and 1 atm at 12 °C. The relative humidity (inside the chambers) was balanced at 98-100%. Mangoes were stored for 2, 4 and 6 days. At the end of each storage period, one batch of the fruits was evaluated immediately and another batch kept in a room with ambient condition (22 °C, 51-53% RH, 1 atm) for a further 3 days. In the second stage the treatments consisted in subjecting the mangoes to pressure conditions of 1, 2, 4, 6 and 8 atm and a temperature of 12 ± 1 ºC. The relative humidity inside the chambers was equilibrated to 98-100% and storage was performed for 6 and 12 days at different pressure levels. At the end of each hyperbaric period, one batch of the fruits was evaluated immediately and another batch kept in a room with ambient condition (22 °C, 83-87% RH, 1 atm) for another 2 and 4 days. Fresh mass loss, skin and pulp color, ascorbic acid, soluble solids content, titratable acidity, total antioxidant activity, phenols, total carotenoids, soluble sugars, polyamines, enzymatic activity and respiratory rate were analyzed. The pressure of 8 atm slowed the ripening of the fruits under ambient conditions and at 12 °C, with lower mass loss, lower SS content and higher AT, lower amount of β-carotene, lower sugar content and reduction of respiratory rate.

A mangueira (Mangifera indica) é uma frutífera de importância comercial no Brasil e no mundo. É cultivada em diversas regiões, incluindo o semiárido e árido irrigados, tais como no Vale do São Francisco, no Brasil, e países como Omã e Paquistão. Nesses locais o déficit hídrico é considerado um dos principais fatores que limitam o desenvolvimento vegetal. Além disso, a murcha-de-ceratocystis, causada por Ceratocystis fimbriata, é uma das principais doenças da mangicultura do Brasil e em Omã e Paquistão. Não há fungicidas eficientes, sendo o método de controle mais eficiente é o uso de variedades resistentes. Levanta-se a hipótese de que o déficit hídrico possa causar da predisposição de infecção de C. fimbriata em variedades de mangueira resistentes. No entanto, até o momento não há estudos sobre a interação entre C. fimbriata e mangueiras submetidas a déficit hídrico. O objetivo deste estudo foi avaliar o efeito do déficit hídrico na incidência e severidade da doença em variedades de mangueiras consideradas resistente à C. fimbriata. Para isso, três variedades de mangueira, „Ubá‟, „Dura‟ e „Manila‟, foram avaliadas quanto à resistência em diferentes condições de déficit hídrico. As mudas de mangueira conduzidas em vaso com substrato comercial a base de pinus foram submetidas a quatro níveis de déficit hídrico e inoculadas com C. fimbriata (CEBS15). Plantas não inoculadas e submetidas aos mesmos regimes hídricos serviram de testemunha. As mudas das variedades „Ubá‟ e „Dura‟ foram conduzidas na mesma época, enquanto que „Manila‟ foi conduzida posteriormente. Cada vaso contendo uma planta foi considerado como uma unidade experimental. Os vasos foram preenchidos com a mesma quantidade (6,8 kg) de substrato. Avaliou-se a mortalidade de mudas mortas, número médio de dias da inoculação até a morte das plantas; potencial hídrico foliar (Ψw), diâmetro de caule (DC), comprimentos das lesões no sentido longitudinal ao caule, área da lesão no sentido radial do caule, severidades das lesões nos sentidos longitudinal e radial, trocas gasosas e na „Manila‟ também se avaliou a fluorescência da clorofila a. Os resultados foram submetidos à análise estatística descritiva. Não houve morte de plantas não inoculadas. A mortalidade foi baixa na „Ubá‟ e alta na „Dura‟, mesmo em condições consideradas sem déficit hídrico. Já na „Manila‟ a viii mortalidade foi alta em déficit hídrico severo apresentando o maior número de dias entre a inoculação e morte. De forma geral, a „Ubá‟ apresentou os menores valores de severidade e comprimento de lesão, sendo que o déficit hídrico influenciou no aumento da lesão. A „Dura‟ apresentou maior severidade e comprimento de lesão, não influenciados pelo nível de déficit hídrico. A „Manila‟ apresentou a maior severidade e o maior comprimento de lesão em 15% da Cp. Houve redução do Ψw e DC das plantas que morreram. As trocas gasosas foram comprometidas nas plantas inoculadas, principalmente nas plantas mantidas sob déficit hídrico severo. Os valores das variáveis de fluorescência da clorofila a apresentaram reduções severas em plantas da variedade „Manila‟ inoculadas e mantidas a 15% da Cp. Concluiu-se que a variedade „Ubá‟ permaneceu resistente, mesmo em condições de déficit hídrico; a „Dura‟ não foi resistente ao isolado CEBS15, mesmo em condições ótimas de irrigação; e a „Manila‟ foi suscetível em condições de déficit hídrico severo.
The mango tree (Mangifera indica) is a fruitful of commercial importance in Brazil and worldwide. It is cultivated in several regions, including the semi-arid and arid irrigated, as São Francisco Valley in Brazil, and countries like Pakistan and Oman. In these places the water deficit is considered one of the main factors that limit plant growth. Moreover, Ceratocystis wilt, caused by Ceratocystis fimbriata, is a major disease of mango in Brazil and Oman and Pakistan. There are no effective fungicides, and then the most efficient method of control is the use of resistant varieties. Raises the hypothesis that water deficit may cause predisposition to infection of C. fimbriata on varieties of mango trees resistant. However, until now there are no studies on the interaction between C. fimbriata and mango trees exposed to water deficit. The aim of this study was to evaluate the effect of drought on the incidence and severity of disease in mango varieties considered resistant C. fimbriata. For this, three varieties of mango, 'Ubá', 'Dura' and 'Manila', were evaluated for resistance in different conditions of water deficit. Seedlings potted mango conducted with commercial substrate base pine were treated with four levels of water deficit and inoculated with C. fimbriata (CEBS15). Plants not inoculated and subjected to the same water regimes served as witness. The seedlings of the varieties 'Ubá' and 'Dura' were conducted at the same time, while 'Manila' was conducted later. Each pot contains a plant and was regarded as an experimental unit. The pots were filled with the same amount (6.8 kg) of substrate. Were evaluated the mortality, average number of days from inoculation to death of plants, leaf water potential (Ψw), trunk diameter (DC), lengths of lesions in the longitudinal direction to the stem, the lesion area in the radial direction of the stem, severity of lesions in longitudinal and radial directions, gas exchange and in the 'Manila' also evaluating the fluorescence of chlorophyll a. The results were submitted to descriptive statistical analysis. No deaths of non-inoculated plants. The mortality was low in 'Ubá' and high in 'Dura', even in conditions considered without water deficit. In the 'Manila' mortality was high in severe water deficit presenting the highest number of days between inoculation and death. In general, the 'Ubá' showed the lowest values of severity and lesion length, and water deficit influenced the increase in lesion size. x The 'Dura' showed greater severity and length of lesion and were not influenced by the level of water deficit. The 'Manila' had the highest severity and lesion length at 15% of Cp. Decreased in the Ψw and DC of plants that died. Gas exchanges were compromised in the inoculated plants, especially in plants grown under severe drought. The parameters of chlorophyll a fluorescence showed severe reductions in inoculated plants of the variety 'Manila' and maintained at 15% of Cp. It was concluded that the variety 'Ubá' remained resilient, even in conditions of water deficit; the 'Dura' was not resistant to the isolated CEBS15, even under optimal irrigation conditions; and the 'Manila' was susceptible in severe water deficit conditions.

Resumo: No Brasil as perdas de produtos hortícolas são significativas e dentre as principais causas cita-se o uso de caixas inadequadas e a ausência da cadeia do frio. As caixas para produtos hortícolas disponíveis no mercado, em sua maioria, são desenvolvidas de forma empírica, sem atender às exigências estruturais e área efetiva de aberturas, para facilitar a troca de calor e ventilação. Este trabalho propõe um método de projeto de caixas para mangas (Mangifera Indica L.), baseado em simulação computacional, otimização e validação experimental, buscando minimizar o volume de material construtivo das caixas (madeira de reflorestamento Pinnus Elliotti), associado a aspectos estruturais, ergonômicos e distribuição da área efetiva de aberturas. Foram projetados e construídos três protótipos de caixas, de ripas retas com diferentes configurações e área efetiva de aberturas (54% e 36%). A eficiência do resfriamento das mangas (variedade Tommy Atkins) foi avaliada através da determinação do tempo de resfriamento de 6 kg de frutas, acondicionadas nos três modelos desenvolvidos, e submetidas ao resfriamento rápido num sistema com ar forçado e duas vazões de ar (0,22 m3 s- 1 e 0,43 m3 s-1), a uma temperatura de 6ºC e umidade relativa média de 85±2,1%. O tempo de resfriamento das frutas também foi determinado quando a mesma quantidade foi condicionada nas caixas de papelão usadas comercialmente (7% e 0% de área efetiva de abertura). Foi aplicado o Método dos Elementos Finitos implementado no programa ANSYS, para o dimensionamento e otimização estrutural do modelo com o melhor comportamento com relação ao resfriamento. Todas caixas de madeira contendo frutas foram submetidas a ensaios de vibração, por um período de duas horas e uma freqüência de 20 Hz. Não houve diferença significativa no meio tempo de resfriamento dos frutos acondicionados nas caixas de madeira (38,00±1,70 min), no entanto na comparação com as caixas de papelão a diferença foi significativa (82,74±29,58 min). O modelo escolhido para a otimização estrutural possuía 36% de área efetiva de aberturas e duas ripas laterais. Após a otimização a diminuição de volume total de material foi de 60% e a redução da seção transversal das colunas da ordem de 83%, com relação às condições iniciais de projeto. Não houve indícios de danos mecânicos nas frutas depois de submetidas à vibração. A simulação computacional para o estudo estrutural, acoplada a algoritmos de otimização, pode ser usada como ferramenta de apoio para desenvolver projetos de caixas de madeira, com grande aproximação, atendendo a critérios geométricos, ergonômicos e térmicos
Abstract: Horticulture product losses in Brazil are significant and among the main causes for this are the use of inappropriate boxes and the absence of the cold chain. Most of the boxes available in the market for horticulture products are developed empirically without satisfying structural demands and the openings effective area for to facilitate the exchange of heat and ventilation. This study proposes a project method for mango boxes (Mangifera Indica L.) based on computer simulations, optimization and experimental validation, seeking to minimize the amount of construction material for the boxes (reforestation wood - Pinnus Elliotti) associated with structural and ergonomic aspects and the openings effective area. Three box prototypes were designed and built using straight laths with different configurations and openings effective area (54% and 36%). The cooling efficiency the mango (Tommy Atkins variety) was evaluated by determining the cooling time for 6 kg of fruit packed in the three different models and submitted to cooling in a forced-air system and two air flows (0.22 m3 s- 1 and 0.43 m3 s-1), at a temperature of 6ºC and average relative humidity of 85±2.1%. Fruit cooling time was also determined when the same amount was packed in the commercially used cardboard boxes (7% and 0% of openings effective area). The Finite Element Method was applied, implemented in the ANSYS program, for the dimensioning and structural optimization of the model with the best behavior in relation to cooling. All wooden boxes with fruit underwent vibration testing for a two hour period at a frequency of 20 Hz. There was no significant difference in average cooling time for fruit packed in the wooden boxes (36.08±1.44 min); however, the difference was significant in comparison to the cardboard boxes (82.63±29.64 min). The model chosen for structural optimization had a 36% openings effective area and two side laths. After optimization, the reduction in total volume of material was 60% and the reduction in the cross section for columns was about 83% compared to the project¿s initial conditions. There was no indication of mechanical damage in the fruit after it underwent vibration testing. Computer simulations for the structural study, together with optimization algorithms, can be used as an effective support tool to develop projects for wooden boxes, with geometric, ergonomic and thermal criteria

Resumo: O presente trabalho teve como objetivo o desenvolvimento de uma tecnologia mais simples para concentração de produtos viscosos e obtenção de polpa concentrada de manga com maior retenção das características sensoriais e nutricionais e boa aceitação do produto por parte dos consumidores. A polpa integral de manga sofreu tratamento enzimático e centrifugação variando-se o número de gravidades e o tempo na centrífuga. Foram separadas duas frações, a polpa precipitada e o suco clarificado de manga. A melhor condição para separação das frações da polpa de manga integral escolhida foi tempo de centrifugação de 15 minutos, número de gravidades 5000G e concentração de pectinase de 16ppm, para obtenção de um rendimento ao redor de 75% de suco clarificado. O suco clarificado foi concentrado por 2,5h quando atingiu 60°Brix. Após isto, o mesmo foi reconstituído com proporções diferentes de polpa precipitada (1= 30%, 2= 67% e 3= 0% de polpa precipitada adicionada), sendo a formulação que obedeceu às frações originais das partes separadas (67% de polpa precipitada) obteve menor brix (29,8°Brix) e diferença total de cor e melhores resultados para teor de carotenóides e fibras. Foram elaborados néctares a partir dos concentrados obtidos e submetidos a análise sensorial. A formulação B (maior teor de polpa precipitada) apresentou os melhores resultados para todos os atributos
Abstract: This study aimed to develop a simpler technology for concentration of viscous products and obtaining concentrated mango pulp with better retention of nutritional and sensory characteristics and good product acceptance by consumers. The whole pulp mango enzyme treatment and centrifugation suffered varying the number of severity and duration of the centrifuge. Two fractions were separated, the pulp and precipitated clarified juice of mango. The best condition for separation of fractions of mango pulp was chosen integral centrifugation time of 15 minutes, number and severity 5000G pectinase concentration of 16ppm, to obtain a yield around 75% of clear juice. The clarified juice was concentrated by 2.5 h when it reached 60 ° Brix. After that, it was reconstituted with different ratios of precipitated pulp (a = 30%, 67% and 2 = 3 = 0% pulp precipitated added), and the formulation that followed the original fractions of the separate parts (67% pulp precipitated) had lower Brix (29.8 ° Brix) and total color difference and better results for carotenoids and fiber. Nectars were prepared from the concentrates obtained and subjected to sensory analysis. Formulation B (higher pulp content hasty) showed the best results for all attributes

Resumo: O consumo de frutas e vegetais tem sido associado com a baixa incidência de doenças degenerativas, pois efeitos protetores estão associados com componentes antioxidantes contidos nestes alimentos. Atrelado a isto, o mercado de sucos e néctares de frutas está sob um aumento significativo, o que tem atraído a atenção de agricultores, distribuidores e da indústria deste produto para saciar esta demanda. Entretanto, estes produtos estão associados à alta ingestão de sacarose proveniente da adição em sua elaboração, o que pode acarretar o desenvolvimento de doenças relacionadas ao consumo excessivo de calorias. A partir disto, este estudo objetivou analisar a aplicação de novos edulcorantes de em néctar de manga pelo estudo de perfil sensorial e físico-químico ao longo do tempo de estocagem. Neste estudo foram utilizadas amostras de néctar de manga elaboradas com polpa de manga congelada e água (1:1) adoçadas com sacarose, sucralose, estévia com 97% de rebaudiosídeo, neotame, blend acessulfame-K/sucralose/neotame (100:50:1) e blend taumatina/sucralose (1:1), totalizando 6 amostras. O perfil físico-químico foi determinado por meio da análise de pH, acidez titulável, cor (L*, a*, b*) e sólidos solúveis (ºBrix). A análise sensorial foi composta por testes descritivos, Análise Descritiva Quantitativa (ADQ) e Análise Tempo-intensidade, além de testes afetivos com escala hedônica e escala do ideal. Além destes, para o estabelecimento de equivalência de doçura foi utilizado o teste sensorial Estimação de Magnitude. A análise estatística foi composta por Análise de Variância (ANOVA), Teste de média de Tukey com nível de significância de 5% para as análises físico-químicas, ADQ, análise tempointensidade e teste afetivo com escala hedônica. O teste com escala do ideal foi analisado por distribuição em histogramas e os dados de estimação de magnitude utilizaram regressão linear em sua análise. Os provadores estabeleceram o valor de 6,8% de sacarose como a quantidade ideal para a intensidade de gosto doce. O neotame foi o edulcorante que apresentou maior poder adoçante, sendo 6026 mais doce que a sacarose, seguindo pela sucralose (627), blend taumatina/sucralose (549), blend acessulfame-K/sucralose/neotame (259) e estévia (134). Os testes físico-químicos e, em especial, a ADQ identificaram a sucralose como o edulcorante que melhor substituiu a sacarose, pois foi o aditivo que apresentou o menor número de diferenças em relação à amostra controle. A análise tempo-intensidade e os testes afetivos também identificaram a amostra sucralose com o melhor perfil relacionado ao estímulo gosto doce, com grande semelhança ao ocorrido com a sacarose e sendo esta a amostra com maior grau de aceitação no tempo zero e a única que se manteve desta forma após os 120 dias de estocagem. Em conclusão, a estévia apresentou melhorias em seu perfil quando comparadas a outros estudos, mas ainda abaixo do esperado para um substituinte de sacarose. A taumatina, uma proteína de origem vegetal apresentou bom perfil e é um aditivo que necessita de maiores estudos para melhoria de sua tecnologia. E, por fim, a sucralose, como já afirmado em outros trabalhos, é o edulcorante que melhor substitui a sacarose em sucos tropicais, sem sofrer alterações significativas após processamento térmico e ao longo do tempo de estocagem
Abstract: The consumption of fruits and vegetable has been associated with low incidence of degenerative diseases, because protective effects has been linked with antioxidant compounds contained in these foods. Attached to this, the consumer market of fruit juices and nectars under a significant increase, which has attracted the attention of producers of these products to satisfy this demand. However, these products are associated with the high ingestion of sucrose from de addition in the elaboration, which may result in the development of diseases associated with the high consumption of calorie. From that, this study aimed to analyze the application of high intensity sweeteners in mango nectar by the sensory and physical-chemical profile during the storage time. Mango nectar samples were prepared with unsweetened mango frozen pulp and water (1:1). The samples were sweetened with different high intensity sweeteners and sucrose. The sweeteners were: Neotame; Sucralose; Stevia with 97% of Rebaudioside; 1:1 Thaumatin/Sucralose blend; 100:50:1 Acesulfame-K/Sucralose/Neotame blend. The physical-chemical profile was determined by: pH, titratable acidity, color (L*, a*, b*), solids soluble (ºBrix). The sensory analysis was composed by descriptive analysis, Quantitative Descriptive Analysis (QDA) and Time-intensity Analysis (T-I), also consumer test with hedonic scale e just-about-right (JAR) scale. Magnitude estimation method was applied to establish the relative sweetness with sucrose. Statistical analysis was composed by analysis of variance and Tukey means test with 5% of significant level to physical-chemical, QDA, T-I analysis, and consumer test. The JAR scale test was analyzed by histograms distribution and the results of magnitude estimation method through linear regression. The ideal sweetness analysis revealed that 6.8% was the ideal concentration of sucrose in the mango nectar. The relative sweetness analysis showed that Neotame presented the highest sweetening power, being 6026 times sweeter than sucrose, followed by Sucralose (627), Thaumatin/Sucralose blend 1:1 (549), Acesulfame-K/Sucralose/Neotame blend 100:50:1 (259) and Stevia (134). The physical-chemical analysis and, in special, the QDA identified sucralose as the best sweetener which best sucrose substitutes, since this additive presented less differences in relation to control sample. T-I analysis and consumers test also identified the sample sucralose with best profile in relation to the sweet stimulus, with great similarity to control sample and being the sample with higher acceptability in initial time and the only one that has remained this way after 120 days of storage. In conclusion, the stevia presented improvements in its sensory profile when compared with others studies,although still lower than expected to a sucrose substitute. The thaumatin, a vegetal protein, presented good sensory profile and is a additive that requires more studies to improve its knowledges. The sucralose, as founded in other studies, is the sweetener that best replace sucrose in tropical fruit juice, with no significant change after heat treatment and during the storage time

Texte intégralIn this research project, the viability of 'Haden' mango puree (Mangifera indica Linn.) as a ready-to-serve product was studied. The ripening process of the fruti was studied to determine the adequate stage for the puree production. Firmness, pH, total acidity expressed as citric acid percentage, soluble solids and pectin content of the fruti pulps were analyzed. results showed that color of skin is a good parameter to indicate the mangoes ripening stage. Four different heat treatments were applied to the acidified puree: 25.5 minutes at 65°C; 16.0 minutes at 75°C; 4.0 minutes at 80°C and 2.5 minutes at 95°C. Non treated and treated puree were maintained under refrigeration for 36 days. pH, titrable acidity, molds and yeast analyses were carried out weekly. Although statistical analyses indicate significant difference among pH and acidity values in relation to storage time and heat treatment, the puree presented acceptable values by Brazilian legislation for mango puree consumed as beverage (pH between 3,3 and 4,5 and mininum total acidity of 0,32% of citric acid). Heat treated puree showed microbiological stability, presenting zero count of these microorganisms during the storage time. The study of rheological behavior of treated and non treated purees revealed non Newtonian character of shear thinning nature. Even though the heat treatments presented very distinct F values, the physical chemical analyses, the mold and yeast counts and the rheological behavior showed that there was difference among the final products. This indicates that the stability os the puree can be achieved applying the heat treatment with the smallest F value, that is 25.5 minutes at 65°C. Consumer acceptance test of puree treated in these conditions presented high level of acceptance, which reinforces the viability of this puree as a ready-to-serve product.

O Manguebit, cena Mangue ou, como é mais comumente conhecido, Manguebeat, movimentação cultural que eclodiu em Recife no início dos anos de 1990, foi abordado por duas dimensões dos impactos que os usos dos aparatos tecnológicos tiveram em relação à autoria. Primeiro, refletiu-se sobre os diferentes horizontes de expectativas mais ou menos rascunhados pelas próprias mídias (LP, K7, CD etc.), nos diversos momentos em que os articuladores do Manguebit as utilizaram em experimentos musicais. Dos K7, o amadorismo e descentramento da figura unitária do autor, às práticas da indústria fonográfica quando contrata alguns mangueboys, o profissional e o filtro imposto pelas estratégias de marketing – negociações do choque de distintos modus operandi. Depois, a construção da cena Mangue foi abordada a partir das estratégias coletivas e o uso de equipamentos e espaços precários enquanto condições de existência, as saídas encontradas pelos mangueboys para a formação de uma cena cultural num momento de extrema hostilidade ao contemporâneo e de forte tensionamento socioeconômico – criação de circuitos alternativos a partir de festas, bares, festivais e coletâneas, o investimento em amplas parcerias e autopromoção.
Manguebit, Mangue scene or, as is more commonly known, Manguebeat – a cultural movement which pop up in Recife in early 1990 – was addressed using two different dimensions of the impacts brought by the use of technological devices on the matter of authorship. First, this study reflects on the different horizons of expectations more or less framed by the media themselves (LP, K7, CD etc.), in the distinct moments in which the organizers of Manguebit utilized them in their musical experiments. From K7 – the amateurism and decentration of unitary figure of the author – to the practices of the music industry when hires some mangueboys, and the professional posture and filters imposed by marketing strategies – including negotiations after shock of different modus operandi. Then development of the Mangue scene was discussed from collective strategies and the use of precarious equipment and spaces as existence conditions, the way outs created by mangueboys to the formation of a cultural scene at a time of extreme hostility to the contemporary and strong socioeconomic tension – creation of alternative circuits with parties, bars, festivals and compilations, extensive investment in partnerships and self-promotion.

Texte intégralThis research analyzes the Mangue [Mangroove] as a cultural phenomenon that distinguishes itself from other local, national and world cultural activities in relation to time and space. As Mangues characteristics may be thought in the same fashion of other cultural aspects that characterize our present time, its possibilities of distinction are analyzed from two distinct perspectives: the formation of identities and the relation between Mangue and the phonographic industry. I assume the hypothesis that the Mangue presents modern, post-modern and global facets, and discuss them from the perspective of arts and the relation between arts, economy and politics. Finally, the analysis suggests that these different temporalities are not mutually exclusive, but concur with each other, rearranging the relation between the parts in order to keep the whole at work
Chuto, Jacques. « James clarence mangan, poete-traducteur ». Paris 3, 1987. http://www.theses.fr/1987PA030037.
Texte intégralDespite all traditional accounts, mangan only knew poverty during the last three years of his life. However, he always was a tormented, eccentric being. In order to write, he needed a mask. This is why most of his 950 odd poems are presented as translations. Though mangan can be a most faithful translator, he often plays the part of a critic, so that translating becomes re-writing: formal embellishments, substitution of ideas, or even parody. It can also end in re-creation, ranging from the adaptation of a single passage to complete appropriation, in which case the english poem is independent of its original. These various practices are found in the three main fields explored by mangan: german, oriental and gaelic poetry. Moreover, the poet sometimes attributes his own poems to foreign writers, real or invented. In fact, mangan needed translation, or the appearance of it, in order to express himself: pretending to be somebody else, his ego thus freed itself from the tyranny of the super-ego. Besides, mangan hated his father, and appropriation was a revenge on all "fathers" (the authors), as well as a rejection of origins which enabled him to assert his originality. Mangan's poetry is mainly a lamentation over the death of the past (whether his own or ireland's) and the emptiness of the motionless present, already haunted by death. This despairng vision (sometimes relieved by mangan's quaint humour) is expressed either in elegiac, melodious verse or with a tremendous intensity achieved through the use of an obsessive refrain or passionate syntax: mangan is first and foremost a great lyrical voice. The second part of this work provides a bibliography of mangan (primary and secondary material), listing most of the sources he used

Texte intégralOne of the major difficulties involved in marketing fresh mango is to manage its quality. Mango quality includes several attributes such as size, total soluble solids content, acidity and color, all of which vary with growing conditions and during ripening. The aim of this thesis is to determine the impact of growing conditions on fruit quality and ripening through experimental and modeling approaches.Experimental studies have revealed that size, dry mass and maturity vary considerably between mangoes according to their position in the tree and fruit load. Measurements suggest that fruit growth is affected by the embolization of sap-conducting vessels. In addition to differences measured between mangoes, our results showed that quality attributes vary within fruits in relation to the maturity gradient.A physical model showed that climatic variations within the tree caused substantial temperature gradients within mangoes that change with the fruit position in the tree. These simulations revealed that quality differences within mangoes are not related to the temperature gradient, except for fruit color. Use of a model that simulates the biosynthetic pathway of ethylene indicated that maturity differences between mangoes are explained by differences in carbon supply and, to a much lesser extent, to differences in temperature. The integration of experimental results into a growth model revealed that the embolization of sap-conducting vessels caused the slowdown of fruit enlargement. Lastly, when all of these models were coupled to a model that simulates fruit growth in dry mass, it was demonstrated that variations in size, dry matter content and maturity between mangoes were caused by differences in fruit load, flowering time, fruit dry mass at the end of cell division and transpiration, rather than by differences in temperature.The multidisciplinary approach developed made it possible to better understand the processes involved in fruit quality and ripening and to open new areas of research

Texte intégralGenetic structuring is common in natural populations. It is important to identify and consider population structure when studying evolutionary processes. Recently, the discovery of genetic structuring in some lekking bird species has opened up new perspectives on our understanding of the evolution of lek mating systems.
This thesis uses molecular data to identify patterns of broad and fine scale genetic structuring in the lekking white-bearded manakin Manacus manacus. Additionally, data on male mating success, female visiting patterns and behavioural, morphological and territorial characteristics of individual males are used to identify variables that may influence the distribution of matings in this species.
Analysis of genetic divergence within the genus Manacus revealed genetic sub-structuring and limited gene flow between species/subspecies. There was no significant isolation by distance relationship. Factors such as physical barriers to gene flow may play a role in shaping the genetic structure of the bearded manakin genus.
White-bearded manakin leks on Trinidad were composed of groups of related males. More than one such kin group existed on each lek. That related males gather in groups suggests that genetic structuring is not simply a consequence of limited dispersal. Active choices must take place by both residential and newly arrived birds.
Female visits to, and matings with, males were non-random. Centrality of male display court was the only measured variable that consistently correlated with male mating success. More aggressive displays were made as the distance between courts decreased. There was no significant relationship between the number of aggressive displays made between males and relatedness levels. Males with high mating success spent more time in aggressive behaviours.
In conclusion, white-bearded manakin lek formation and display court acquisition is likely to be influenced by genetic relatedness levels and male-male interactions. Centrality of court seemed important in mating success and may be an indicator of male dominance. However, a variety of other factors may also influence mating success and may be variable over time.

Resumo: O Brasil possui um grande potencial de produção de sucos de frutas tropicais, entre os quais destaca-se o suco de manga. Por outro lado, a preocupação com a saúde impulsionou a pesquisa e o desenvolvimento de alimentos de baixa caloria e adoçantes não calóricos. Os edulcorantes podem produzir características sensoriais indesejáveis, sendo necessário estudá-los, individualmente, no alimento ou bebida aos quais são adicionados. Este trabalho teve por objetivo estudar o comportamento do suco de manga concentrado e da polpa de manga congelada, ambos reconstituídos e adoçados com diferentes edulcorantes (mistura ciclamato/sacarina 2:1, aspartame, sucralose e extrato de folhas de estévia) e com sacarose, sob o ponto de vista físico-químico e sensorial. Foram realizadas determinações fisico-químicas (pH, acidez titulável, sólidos solúveis e totais, açúcares redutores e não-redutores, e cor), determinação de doçura equivalente, análise descritiva quantitativa (ADQ), análise tempo-intensidade (ATI) e análise de aceitação. Os dados obtidos na análise descritiva quantitativa, e os dados dos parâmetros obtidos nas curvas tempo-intensidade foram avaliados através de análise de variância (ANOVA), testes de médias de Tukey e análise de componentes principais (ACP). Todas as análises estatísticas foram realizadas utilizando-se o programa SAS. A concentração ideal de sacarose a ser adicionada ao suco e à polpa de manga foi de 8 e 7,5%, respectivamente. A estévia apresentou o menor poder edulcorante e a maior diferença de potência em suco e em polpa de manga. Os demais edulcorantes apresentaram comportamentos semelhantes em suco e em polpa de manga em relação ao poder edulcorante, sendo a maior potência exibida pela sucralose. Na análise descritiva quantitativa, a estévia caracterizou-se por apresentar níveis elevados de doçura residual, amargor e amargor residual. A análise tempo-intensidade avaliou os estímulos doce, amargo e sabor de fruta, em suco e em polpa de manga. Na análise tempo-intensidade, a estévia apresentou a maior intensidade máxima para os estímulos doce e amargo, e esta característica persistiu por um longo período, confirmando a presença de doçura e de amargor residual intenso na amostra. A sacarose caracterizou-se por apresentar gosto doce limpo, sem residual amargo. Em relação ao estímulo sabor de fruta, a sacarose exibiu a maior intensidade máxima, e o aspartame o maior tempo total de duração do estímulo, indicando potencialização do sabor de fruta por este edulcorante. O aspartame e a sucralose foram os edulcorantes, cujo comportamento sensorial mais se aproximou ao da sacarose, na análise descritiva quantitativa e na análise tempo-intensidade. As maiores médias de aceitação, em relação ao sabor e à impressão global, foram exibidas pelas amostras adoçadas com sacarose, aspartame e sucralose, indicado que a aceitação do produto está diretamente relacionada à intensidade de doçura residual, amargor e amargor residual presentes no produto
Abstract: Brazil has a great potential for tropical fruit juice production, amongst which mango deserves special attention. In addition concern about health given inpetus to research and development on low calorie foods and non-caloric sweeteners. Alternative sweeteners can produce a variety of indesirable sensory characteristics, it being necessary to study them individually in the specific food or beverage. The objective of this study was to sensorially evaluate, industrialized reconstituted mango juice and mango pulp, sweetened with various edulcorants (mixture of cyclamate/saccharin 2:1, aspartame, sucralose and stevioside leaf extract) and sucrose. Physicochemical (pH, titratable acidity, total and soluble solids, reducing and non-reducing sugars and colour) determinations were carried out and also sensory analysis such as ideal sweetness using the just-about-right scale, sweetness equivalents, quantitative descriptive analysis, time-intensity analysis and acceptability of the sweetened mango juice and pulp with sucrose and with the edulcorants cited above. The quantitative descriptive analysis, time intensity analysis and acceptance test data were evaluated by the analysis of variance (ANOVA), Tukey¿s Test and the principal component analysis. The statistical analysis was carried out using the SAS program. The optimum sucrose concentration was 8% in mango juice and 7.5% in mango pulp. The results showed that sucralose had the greatest potency amongst the four intensity sweeteners tested in mango juice and pulp, while stevia leaf extract exhibited the smallest. Stevioside leaf extract was characterized by a strong bitter taste, sweet aftertaste and bitter aftertaste in the quantitative descriptive analysis. Sweetness, bitterness and fruitiness were evaluated by time-intensity methodology for mango juice and pulp. Stevioside leaf extract time-intensity curves showed a significantly longer sweet and bitter aftertaste than other sweeteners. Sucrose displayed a clean sweet taste with no unpleasant aftertaste. Sucrose had a higher intensity of fruit flavor and aspartame elicited significantly longer persistence of fruitiness, suggesting an intensification effect. The sensorial profiles of aspartame and sucralose were similar to that of sucrose in the quantitative descriptive analysis and time-intensity analysis. The acceptance test showed that the formulations with sucrose, aspartame and sucralose were similar in all attributes and had the highest acceptability. This observation suggests that the acceptance of a sweetener is related to the intensity of sweet aftertaste, bitter and bitter aftertaste

Texte intégralThe central characters of this research are the otakus, who can be described as fans of mangá and anime, who spend much of their time entertained with these (and some others) elements of Japanese pop culture, a linkage that influences their worldview and the way they act in their daily lives. The central focus of the research is the quest for understanding the relationship between fiction and reality. My assumption is the idea that fiction is not simply a product of the sociocultural context in which it is produced: in fact it is a product of this context, but as it is a way of reading, a way of seeing, which goes beyond the limits of reality, fiction may be thought of as an active agent, transformer, an agent that stimulates the construction of new insights about the world around us.

Texte intégralThe mango ripening process and the associated physiological and biochemical changes is still poorly known. Also is unknown if the bulk of sugar is accumulated prior or after the onset of ripening. The aim of this work was to evaluate the soluble sugars, starch and ascorbic acid content during the growth and ripening of several mango varietes. The sucrose-phosphate synthase (SPS) and sucrose synthase (SS) activities were evaluated in Van Dyke mango variety. The post harvest respiration and ethylene profiles of the Van Dyke, Tommy Atkins and Haden varieties were analyzed after harvesting. The results shown that the changes on total sugar profiles were highly dependent on the cultivar and physiogical maturity. Sucrose was the predominant sugar in ali analyzed varieties. The fructose amount was 2,5 to 48 times higher than glucose being the predominant hexoses in ripe fruit. The starch content of any variety of harvested mango is too low, with values under 3,0%. The sucrose related enzymes (SPS and SS), showed an increasing activity during the post-harvest ripening of Van Dyke\'s cultivar. For most varieties, the ascorbic acid content decreased before the harvest point, except for Keitt and Tommy Atkins mangos. The highest ascorbic acid content was found in the ripened Tommy fruit. One increase in the ethylene was not detected after harvesting. More than one respiration peak was detected for Haden and Van Dyke\'s varieties, this result is different of the other climacteric fruit\'s one.

Texte intégralDans ce travail de thèse, nous nous intéressons au séchage de tranches de mangues. L’ob- jectif principal est de contribuer au développement d’une nouvelle technologie de séchage, adaptée aux pays en voie de développement et fonctionnant entièrement à l’énergie solaire. Cette nouvelle technologie a pour but d’améliorer la qualité du séchage et la productivité des séchoirs.
D’après les techniques traditionnelles de séchage présentées dans la littérature, nous choi- sissons la structure générale qu’aura la nouvelle technologie de séchage :un capteur solaire couplé à une tour de séchage, alimentée en air par des ventilateurs placés à l’entrée du capteur solaire et reliés à un panneau photovoltaïque. Cette technologie fonctionne en mode indirect :les zones de chauffe de l’air et de séchage sont différentes. Les tranches de mangues à sécher sont placées sur des plateaux dans la tour de séchage et l’écoulement de l’air se fait perpen- diculairement à ces plateaux. Nous avons l’idée originale d’ajouter des éponges et un grillage métalliques afin d’augmenter les transferts de chaleur à l’intérieur du capteur solaire.
Un premier prototype de cette nouvelle technologie est dimensionné, sur base de l’expres- sion de bilans de matière et d’énergie. Un cahier des charges doit être rempli, notamment en termes de temps de séchage, de température de l’air sortant du capteur, d’humidité finale des mangues séchées et de masse de mangues fraîches à sécher.
D’après l’étude de ce prototype, imaginé et construit en collaboration avec la société Solvay, nous développons, pour la nouvelle technologie de séchage, un modèle du capteur solaire et un modèle de l’écoulement de l’air au sein de cette technologie. Le modèle du capteur solaire est utilisé pour déterminer le coefficient de transfert de chaleur par convection entre l’air au sein du capteur et ses parois. Nous montrons que ce coefficient est très élevé, à tel point qu’il est indissociable de celui qu’aurait un capteur idéal. Les performances du capteur solaire sont donc très bonnes. Nous montrons qu’elles sont particulièrement améliorées par l’ajout des éponges et du grillage métalliques dans le capteur. Le modèle de l’écoulement de l’air décrit le lien entre la puissance fournie à l’air et le débit d’air qui circule dans le séchoir. Nous l’utilisons pour déterminer le coefficient de perte de charges d’un plateau chargé de mangues.
A plus petite échelle, nous étudions la vitesse de séchage d’une tranche de mangue, au sein d’un petit séchoir disponible au laboratoire TIPs de l’ULB. Plusieurs expériences de séchage y sont réalisées dans des conditions bien contrôlées. D’après ces essais, nous développons un modèle mathématique original de la vitesse de séchage d’une tranche de mangue qui nous permet de prédire la vitesse de séchage de tranches de mangues dans des conditions opératoires données. Une très bonne correspondance est obtenue entre les simulations du modèle et les résultats expérimentaux. Il peut donc être utilisé pour prédire la vitesse de séchage de tranches de mangues pour une large gamme de conditions opératoires.
Ce modèle est couplé à des bilans de matière et d’énergie, relatifs à la tour de séchage. Nous obtenons dès lors un modèle de fonctionnement de la tour de séchage de la nouvelle technologie.
L’ensemble des modèles développés pour caractériser le fonctionnement du capteur solaire, l’écoulement de l’air dans la technologie de séchage et le fonctionnement de la tour de séchage sont alors combinés pour obtenir un modèle complet de fonctionnement de la nouvelle tech- nologie de séchage. Ce modèle est validé et le fonctionnement de cette nouvelle technologie est optimisé par l’ajout d’une phase de permutation des plateaux après la moitié du temps de séchage. Ce modèle complet de la technologie de séchage est alors utilisé pour dimensionner des séchoirs de terrain pour une période donnée de l’année, en un endroit donné.
Nous terminons ce travail de thèse en présentant une comparaison entre un séchoir de terrain de la nouvelle technologie et un séchoir Atesta, qui est la technologie traditionnelle de séchage de mangues la plus répandue en Afrique de l’Ouest. Nous concluons que la quantité d’eau évaporée par unité de temps est bien supérieure pour le séchoir de terrain que pour l’Atesta. Le coût de fonctionnement d’un séchoir de terrain est plus faible que celui d’un séchoir Atesta car le séchoir de terrain fonctionne entièrement à l’énergie solaire et non pas au gaz, comme c’est le cas pour le séchoir Atesta. La qualité des mangues séchées obtenues dans un séchoir de terrain est supérieure à celle obtenue dans un séchoir Atesta car il n’y a pas de contact avec les gaz brûlés et la convection de l’air y est forcée. Néanmoins, l’encombrement au sol des séchoirs de terrain reste un point négatif en comparaison avec le séchoir Atesta du fait de la grande taille du capteur solaire.

The mango crop is one of the principal activities of Brazilian agribusiness. The mango is present in all Brazilian territory, but the economic cultivation is concentrated in the Northeast and Southeast of Bra zil. Among the cultivars of most important commercial, Tommy Atkins is the most cultivated and exported. Most fruits and vegetables have a natural layer of wax on the surface and applying a coating serves to increase the physical, chemical and microbiological stability. The present study aimed to develop edible coatings based on wax added to the antimicrobial triclosan and sorbic acid in order to extend the shelf life of harvested mango ( Mangifera indica L.) variety 'Tommy Atkins. The fruits were subjected to four treatments: mangoes washed and sanitized (control); mangoes washed, sanitized and with carnauba wax (control with wax), mangoes cleaned, sanitized, with waxes and triclosan 1% (carnauba wax with triclosan) and mangoes washed, sanitized, with waxes, and sorbic acid 0.1% (carnauba wax with sorbic acid) for 35 days of storage. The treatments were analyzed using physical, chemical, physico - chemical, microbiological and sensory analysis.
A mangicultura é uma das principais atividades do agronegócio frutícola do Brasil. A manga está presente em todo território brasileiro, mas o cultivo econômico concentra-se nas regiões Nordeste e Sudeste. Dentre as cultivares de maior importância comercial, Tommy Atkins é a mais cultivada e exportada. A maioria das frutas e hortaliças possui uma camada de cera natural na superfície e a aplicação de um revestimento serve para aumentar a estabilidade física, química e microbiológica. A adição de agentes antimicrobianos tem como objetivo limitar ou prevenir o crescimento microbiano. Diante do exposto, o presente trabalho teve como objetivo desenvolver revestimentos comestíveis a base de cera de carnaúba adicionada dos antimicrobianos triclosan e ácido sórbico visando o prolongamento da vida útil pós-colheita da manga (Mangifera indica L.) variedade “Tommy Atkins”. Os frutos foram submetidos a quatro tratamentos: Mangas lavadas e sanificadas (Controle); Mangas lavadas, sanificadas e com cera de carnaúba (Controle com cera); Mangas lavadas, sanificadas, com cera de carnaúba e triclosan a 1% (Cera de carnaúba com triclosan) e Mangas lavadas, sanificadas, com cera de carnaúba e ácido sórbico a 0,1% (Cera de carnaúba com ácido sórbico) por 35 dias de armazenamento. Os tratamentos foram submetidos às análises física, química e físico-química, microbiológica, microscópica e sensorial.

Texte intégralMango fruit (Mangifera indica L.) is cultivated in tropical and subtropical areas, mainly in developing countries. India, China, Mexico, Indonesia, Thailand, Pakistan and Brazil are the major producers, but its trade has been limited due the highly perishable nature of the fruit. During ripening, the fruits acquire characteristics that make them appropriate for consumption as a consequence of metabolic changes dependent on the expression of specific genes. As proteins are the effector elements of gene expression, proteome analysis can help the identification of metabolism keypoints that could influence the fruit quality. Thus, the aim of this study was to compare the protein maps of mango pulp (Mangifera indica L. cv. Keitt) in pre-climacteric and climacteric stages, in order to identify protein spots that differ in abundance in these two stages. After protein extraction and separation by 2D-DIGE technique, the gel images obtained were analyzed with PDQuest software, using the Student´s T-test for statistical analysis. We obtained 47 spots differently abundant between the stages studied, that were excised from the gels and its proteins digested with trypsin and sequenced by mass spectrometry. We obtained the identities of 58 distinct proteins from the search of the peptide sequences against NCBI2010 database using the software Mascot.

Foram desenvolvidas, validadas e aplicadas duas metodologias analíticas por SPME e análise por GC-MS e HPLC-UV-Vis, para determinar resíduos de agrotóxicos em manga. 14 compostos foram analisados por GC-MS (clofentezina, carbofuran, diazinon, parationa, malationa, fentiona, tiabendazol, imazalil, bifentrina, permetrina, procloraz, piraclostrobina, difenoconazol, azoxistrobina) e 10 por HPLC-UV-Vis (tiabendazol, carbofuran, azoxistrobina, procloraz, fentiona, clofentezina, permetrina, abamectina, carbosulfan e bifentrina). Diferentes parâmetros que influenciam na eficiência da extração foram avaliados (Tipo de fibra, modo de extração, temperatura e tempo de extração e dessorção, velocidade de agitação e força iônica). Os melhores resultados foram obtidos com fibra de PA e DI a 50°C por 30 min, com agitação a 250 rpm e dessorção por 5 min a 280°C no GC- MS e no modo estático por 15 min na interface SPME-HPLC. Na validação foram avaliados o efeito da matriz, a linearidade das curvas analíticas, LOD, LOQ, precisão e exatidão. O método por SPME-GC-MS apresentou linearidade entre 3,3 e 1665,0 µg kg-1, LOD entre 1,0 e 3,3 µg kg-1 e LOQ entre 3,3 e 33,3 µg kg-1. O método por SPME-HPLC- UV-Vis apresentou linearidade entre 2,0 e 250,0 µg kg-1, LOD entre 0,6 e 3,3 µg kg-1 e LOQ entre 2,0 e 10,0 µg kg-1. Nos dois métodos foram obtidos CV menores que 20%. Os métodos foram aplicados na análise de amostras coletadas em Salvador-BA e Aracaju-SE. Nas amostras de Salvador foram detectados resíduos de sete compostos e nas de Aracaju resíduos de cinco compostos. Entretanto, as concentrações estavam abaixo dos valores estabelecidos pela Legislação Brasileira.
Were developed, validated and applied two analytical methodologies by SPME and GC-MS and HPLC-UV-Vis analysis to determine pesticide residues in mango. 14 compounds were analyzed by GC-MS (clofentezine, carbofuran, diazinon, methyl parathion, malathion, fenthion, thiabendazole, imazalil, bifenthrin, permethrin, prochloraz, pyraclostrobin, difenoconazole, azoxystrobin) and 10 for HPLC-UV-Vis (thiabendazole, carbofuran, azoxystrobin, prochloraz, fenthion, clofentezine, permethrin, abamectin, bifenthrin and carbosulfan). Different parameters influencing the extraction efficiency were evaluated (fiber type, extraction mode, temperature, extraction and desorption times, stirring velocities and ionic strength. The best results were obtained using PA fiber and DI mode at 50°C form 30 min, along with stirring at 250rpm and desorption for 5 min at 280°C in the GC-MS and estatic mode for 15 min in the SPME-HPLC interface. For validation, we assessed the matrix effect, the linearity of calibration curves, LOD, LOQ, precision and accuracy. The method for SPME-GC-MS showed linearity between 3.3 and 1665.0 mg kg- 1, LOD between 1.0 and 3.3 µg kg-1 and LOQ between 3.3 and 33.3 µg kg-1. The method for SPME-HPLC-UV-Vis showed linearity between 2.0 and 250.0 µg kg-1, LOD between 0.6 and 3.3 µg kg-1 and LOQ between 2.0 and 10.0 µg kg-1. In both methods were obtained CV below 20%. The methods were applied in the analysis of samples collected in Salvador- BA and Aracaju-SE. In samples from Salvador seven compounds residues were detected and in samples from Aracaju five compounds residues were detected. However, the concentrations were below the values established by Brazilian legislation

O processo identitário dos adolescentes consumidores de mídias nipônicas, conhecidas como animês e mangás, e o modo com o qual essas mídias atuam na vida de alunos de uma escola do Ensino Fundamental, anos finais da rede pública do Distrito Federal, são os temas que deram origem à pesquisa aqui apresentada. Neste trabalho, exploro como se dá tal influência, caso ela ocorra; e por que é importante para esses jovens o contato constante com essas mídias. O marco teórico está delimitado a autores da cultura visual, da educação da cultura visual, da educação estética, da identidade, histórias em quadrinhos, neotribos entre outros. A pesquisa de campo ocorre dentro de uma escola pública situada na Região Administrativa da Ceilândia de ensino integral. Quanto à metodologia, foram feitas entrevistas com grupos de alunos em um primeiro momento, depois foi socializado trabalhos feitos pelos alunos durante a entrevista. As perguntas da entrevista foram abertas norteadoras com base no formato de diálogo e pautadas em três tópicos:(1) questões de estudos; (2) proposições e unidades de análise, de modo a verificar se há influências por parte dos animês e mangás na vida desses/dessas jovens; e (3) como se dá tal influência e por que essas mídias são importantes para seus consumidores. Concluindo que esses elementos áudio visuais são constituintes da formação de identidades desses jovens e que tal influência se dá tanto por conta de familiares quanto de amigos no ambiente escolar, e isso aparece em seus diálogos, afirmações, produções escolares e lazer.
The identity process of adolescents who consume Japanese media, known as anime and manga, and the way these media influence the lives of students in the final years of elementary school belonging to a public school in the Federal District are the themes that determined the present research. In this work, it will be explored how this influence occurs, if it occurs, and what is the importance for these young people the constant contact with these media. The theoretical framework is limited to authors of visual culture, visual culture education, aesthetic education, among others. Field research occurs in a public school located in the administrative region of Ceilândia. In relation to the methodology used, interviews with groups of students were done, initially, and later individually. In regards to the methodology, interviews were made with student groups at a first stage, with later stages socializing papers made by themselves during the interviews. The questions for the interview script were open ended following a guideline with base on the speech and following 3 directives : (1) study questions; (2) propositions and units of analysis, in order to verify if there is influence of animes and manga in the life of these young people; (3) how this influence occurs and why such media are important to their consumers.

Texte intégralThis research in question have studied the manga as media communication, evidencing in its images some modern and post modern characteristics. The manga – Japanese comics – images have been analyzed according to modern and post modern perspectives, being through its definition and history to the effective analysis of its symbolical patterns, finding in them plural and hybrids characteristics, so common to the post modern condition, as well as values like goodness and evil, as the ones from the modern period. In this context, it have been searched for references in order to acknowledges the manga as media communication, and capable to create new reflections and knowledge as well. This research is a qualitative and descriptive study, based upon an hermeneutics interpretation method suggested by Thompson (1995). Beyond the theoretical revision, this essay presents the analysis of manga reader’s depositions, to the one better comprehension about the reason of the manga’s consume in Brazil. Statements were collected by non standard interviews in depth, as indicated for qualitative research by Bardin (1977). The interviews have been occurred individually, and analyzed focusing on depth hermeneutics according to Thompson (1995). The group of interviewed subjects was composed of three college students, one who have completed school studies and three school students. All interviewed subjects were between 15 and 25 years old. By the analysis of collected data, it was evident that the manga is capable to communicate, being a product from the oriental culture so different from the occidental culture in which we live in. The essay also put in evidence that the manga has moderns and post moderns characteristics as well, so that is not secure to declare it as modern or post modern.
Na presente pesquisa foi estudado o mangá como um meio de comunicação, evidenciando suas características modernas e pós-modernas através de suas imagens. As imagens dos mangás – histórias em quadrinhos japonesas – foram analisadas a partir das perspectivas moderna e pós-moderna, passando por sua definição e história para a efetiva análise de suas formas simbólicas, nelas encontrando, características plurais e híbridas, comuns à condição pós-moderna, bem como valores claros entre bem e mal, como aqueles presentes na modernidade. Neste contexto, buscaram-se referências que entendam e valorizem o mangá como meio de comunicação e gerador de novas possibilidades de reflexões e conhecimentos visuais. Trata-se de um estudo qualitativo e descritivo, que se baseia numa metodologia de interpretação hermenêutica sugerida por Thompson (1995). Além da revisão teórico-bibliográfica, este trabalho apresenta a análise de depoimentos de leitores de mangá para um melhor entendimento do motivo de consumo deste no Brasil. Os depoimentos foram coletados sob a forma de entrevista despadronizada em profundidade, conforme indicada para a pesquisa qualitativa por Bardin (1977). As entrevistas ocorreram individualmente, e foram analisadas com o enfoque da hermenêutica de profundidade, de acordo com Thompson (1995). O conjunto de entrevistados constituiu-se de sete sujeitos, sendo três estudantes universitários, uma estudante com Ensino Médio completo e três estudantes de Ensino Médio. Todos os entrevistados encontravam-se na faixa etária entre 15 e 25 anos. A análise dos dados coletados evidenciou que o mangá é capaz de comunicar, mesmo sendo produto de uma cultura oriental notoriamente diferente da ocidental na qual vivemos. O trabalho evidencia também, que os mangás contém características tanto modernas quanto pós-modernas, sendo assim duvidoso afirmá-lo como moderno ou pós-moderno.

Texte intégralForam realizados experimentos para determinar a influência de diferentes concentrações salinas (0, 50, 250 e 500 mM de NaCl), sob fotoperíodo de 12 horas e temperatura de 25°C no desenvolvimento de propágulos de Rhizophoramangle L. coletados no manguezal da Guaxindiba, município de Conceição da Barra, Espírito Santo, Brasil. O experimento foi conduzido em câmara germinadora e delineado em blocoscasualizados, bloco 1 (não sombreado), bloco 2 (sombreado) e bloco 3 (duplamente sombreado). No estágio anterior a inserção de NaCl, os propágulos cultivados nos blocos sombreados (blocos 2 e 3) tiveram um incremento de peso inicial (IPI) significativamente maior que os propágulos cultivados no bloco não sombreado. A partir da inserção de sal o fator bloco se tornou secundário, e o sal passou a ser o fator determinante para o desenvolvimento dos propágulos. Oincremento de peso final (IPF) foi significativamente maior notratamento com 50 mM de NaCl, intermediário no tratamento com 250 mM e menor no tratamento com 500 mM de NaCl.Em produção de biomassa seca de raiz e parte aérea houve diferença significativa na interação tratamentos x blocos, para a biomassa seca de hipocótilo não houve diferença significativa entre tratamentos, blocos e na interação tratamentos x blocos. Concluímos que o sombreamento e a salinidade (0 a 500 mM) influenciam no desenvolvimento inicial dos propágulos de R. mangle.

Texte intégralThis thesis is an analysis of the contemporary eater's material and imaginary experience. The investigation field includes every step of the culinary pattern: home production, shopping, storage, cooking and eating manners. Moreover, a specific inquiry was performed about slimming diets. This work underlines how eaters' behaviours are structured according to three fundamental logics (“functional”, “dietetic” and “authentic”). Actors try to combine them, but never achieve completely to do it. From this point of view, the food experience could be characterised by a habit system open to reflexivity. Food reflexivity is not built on vacuum; it lies within a pluri-dimensional framework (cultural, environmental, biographical and social) which constitutes “horizons of potentialities”. Finally, with the particular case of feminine dieting experience, we show that the relation to the self, induced by food practises, is not limited to narcissism or disciplinary interiorization, but include a part of subjectivation

Texte intégralA new method of analysis of social representations is applied to the representations of . The theory of social representations developed by the french school of moscovici is presented with a new formalism based on combinatory analysis. This formalism of "relativity complete" describes simply the propagation of social representations in populations, and their pragmatic functions. Upon this formation, we build a theory for extracting the basic constitutive elements of a representation from large corpora of statements in natural language. This theory is then applied in the form of a methods and techniques to collect and analyse textual data. These techniques are first applied to 2 corpora about coming from, respectively, free associations by 2000 french adults, and 500 definitions from a large dictionary. These analyses yield similar results : is made out of six nuclei of meaning : libido, intake, food, meal, fillingup, living. Analysis of free associations about by another sample of 2000 french adults then enlightens the theoretical relationship between representation and behaviour, from, among others, a deep field study on 1600 french households (several hundreds questions), the main types of eating behaviour and representations of the french are described, and the extent of influence of representations upon behaviour is measured. Finally some new hypotheses on the developmental laws of individual representations are suggested, among which the (development of the most used aspects), and on the ecology of social representations as populations of individual representations, in a constructionnist perspective

Texte intégralIntroducing taste as a fine art ingredient in the artistic and gastronomic process is a way of building a free and surrealist language, by which the gustatory becomes a graphic pattern. Dots, lines, colors are given to the viewer as an aesthetic and pleasurable tasting. Eating art invites you to redefine the essence of gastronomy and the aesthetic of taste in the field of fine art. It is an artistic starter to understand culinary art, and a culinary starter to appreciate fine art. From Zurbaran dark backgrounds to Bras roasted blacks, how to translate the (sacralisation) of taste as a sensitive, aesthetic and artistic experience? From a concept to a shared practice, the space-plate becomes an architectural space and, finally, a gourmet space. The architectural space being at the start of the artistic and gastronomic projects, the edible installations are created from the (space body/structure), so that the “gourmandise”, an immaterial and imaginary concept, takes shape in a total art work

Texte intégralThe fruit development and ripening are organized and complex processes where phytohormones, like indol-3-acetic acid (IAA), abscisc acid (ABA) and ethylene have a pivotal role. In mango fruit one of the main metabolisms that have direct impact in the mango quality is the starch degradation, practically being all degrated the synthesis of sacarose. Some enzymes participate of the degradation, as hidrolases (alfa and beta-amylases, disproportionating enzymes) and phosphorylases, described also in bananas. The mobilization of the starch in Keitt mangoes it does not seem to be temporally associated with ethylene; and variations in the IAA and ABA levels suggest their possible role in the signalling for the starch. Sucrose biosynthesis was delayed by 1-MCP indicating a reduction in the speed of the carbon flux from the starch that it can be, resultant of the alterations in the metabolism of maltose provenient from the starch degradation.

Texte intégralThe mango (Mangifera indica L.) is a tropical fruit of Asiatic origin and one of the main fruits traded worldwide. The mango crop presents a potencial for further expansion of fruits and derivative trades mainly export qualities. The average world production is 26 million tons. Breeding programs need to develop mango cultivars having the highest aggregate number of agronomic traits. Knowledge of both the genetic variability and structure is aimed by mango culture breeders due to perennial species as well as to the long period of time to obtain new cultivars. In this study, the genetic diversity and structure of the germplasm bank in 151 acessions of mango were analyzed. At first, 23 microsatellite markers were developed in order to extract molecular information from bank germplasm. It was possible to detect that the SSR loci were highly informative in the studied population. Averages were obtained of He = 0.655, Ho = 0.496 and PIC = 0.621. Next, with the molecular data it was possible to estimate the genetic diversity and structure of the 151 acessions as well as observe 144 alleles with an average of 7.2 per locus with amplitude between 2 and 12 alleles; the average gene diversity was 0.689. In all simulations there were consistent statistic analyzes enabling the clustering cultivars in two groups. A group was formed by Brazilian landraces and a second group was formed by North American landraces and Brazilian new hybrids. A core collection of 30 acessions was able to keep 100% of the alleles representing the molecular diversity of 151 mango cultivars. To provide more information to the Embrapa germplasm mango tree, 103 acessions containing information from 20 microsatellite loci and average of 48 agronomic traits were assessed together by the method of Tocher and formed 23 groups. Twenty two groups were formed by more than 50% of acessions while 10 groups were formed by a single acession each. An interactive test was conducted from molecular and qualitative phenotype data which resulted in two consistent clusters.
