Full textAbstract:
Fruit sweetness is the major determinant of fruit quality in melons (Cucumis melo L.) and reflects the concentration of the three major soluble sugars, sucrose, glucose, and fructose, present in the fruit flesh. Of these three sugars, sucrose is the prime factor accounting for both the genetic and the environmental variability observed in sugar content of C. melo fruit. Faqqous (subsp. melo var. flexuosus), a cultivar having a low sucrose and total sugar content, was crossed with Noy Yizre'el (subsp. melo var. reticulatus), a cultivar having a high sucrose and total sugar content. F1 plants had a sucrose content averaging slightly higher than that of the low-sucrose parent, indicating that low sucrose content is nearly completely dominant. Segregation in the F2 and backcross progenies indicated that high sucrose accumulation in melon fruit flesh is conferred by a single recessive gene herein designated suc. When the high-sucrose parent was crossed with the moderate-sucrose landrace known as Persia 202 (subsp. melo var. reticulatus), the segregation in the filial and backcross progenies suggested that additional genetic factors affect the amount of sucrose accumulation.

Full textAbstract:
As part of a program to develop a model for growth and development of muskmelon produced under various mulch and row cover combinations, all perfect flowers of five plants were tagged and measured on a daily basis. The polar and equatorial lengths of the inferior ovary were recorded from anthesis to fruit maturity. Mature fruits were harvested at full slip. The location of each flower on the plant was coded. Flowers and subsequent fruits were classified according to the following phenological stages: immature, close to mature, close to full bloom, full bloom, wilted, past full bloom, close to fruit, fruit. The netting was visually evaluated and rated on a scale of 0 to 5, the highest value representing maximum netting. At fruit maturity, the weight, polar and equatorial length of each fruit were measured and mature and immature seeds counted. The number of fruits that reached maturity was directly proportional to the total number of perfect flowers produced on a plant. Fruit weight during growth could be predicted from the polar and equatorial lengths.

Full textAbstract:
This article examines the nutritional quality and human health benefits of melons, specifically, muskmelon or cantaloupe (Cucumis melo L. var. reticulatus Naud.) and honeydew melon (Cucumis melo L. var. inodorus Naud.) types. Melons are naturally low in fat and sodium, have no cholesterol, and provide many essential nutrients such as potassium, in addition to being a rich source of beta-carotene and vitamin C. Although melons are an excellent source of some nutrients, they are low in others, like vitamin E, folic acid, iron, and calcium. Since the U.S. diet is already high in fat and protein content, melons should be included in everyone's diet, along with five to eight servings per day of a variety of other fruit and vegetables, to ensure adequate nutrition, promote individual health, and reduce one's risk of cancer and certain other chronic diseases.

Full textAbstract:
Landlords and cultivators of watermelon ( Citrullus lanatus) and several other types of melons ( Cucumis melo var. Cantalupensis, Cucumis melo var. Reticulatus, Cucumis melo var. Cucumis melo Inodorusvar, etc.) complained about soil degradation due to cultivation of melons without judicious use of pesticides. Conducting a field survey on the use of pesticides and the prevalence of pesticide residues in the soil of melon-cultivated areas, the study investigates the authenticity of such claims and figures out the actual reasons for such land degradation. The survey was carried out on 150 farmers from 30 villages in Kyaukse, Myitthar and Tada U Township in Mandalay division of Myanmar. The survey captures information on pesticide-related awareness, attitudes and practices and identifies possible health and environmental risks. The usage, storage and handling of pesticides by most of the respondents were found not safe, and knowledge on the adverse effects of pesticides on health, crops and the environment was found to be inadequate. The findings have indicated the potential risk of soil degradation. It appears that lack of cooperation among the government, non-governmental organisations (NGO), private sector stakeholders and farmers is the key weakness for improving agricultural practices adopted by farmers. Enhancing the awareness, changing the attitudes and improving the practices of the farmers regarding the use of pesticides may be the key step towards addressing this issue.

Full textAbstract:
`Galia' is a high-quality muskmelon cultivar that is grown in green-houses or tunnels to maximize fruit yield and to help improve fruit quality. Maximum fruit quality and flavor are achieved when `Galia' are harvested at maturity. This however leads to reduced firmness and short shelf life. In vitro regeneration and transformation of `Galia' melon is a strategy that can be used to increase fruit shelf life. Melon cotyledons were transformed with the ACC oxidase gene in antisense orientation according to the protocol described by Nunez-Palenius et al. (2001, 2003). Experiments were conducted to compare fruit quality parameters between transgenic (TT) and wild type (WT) fruits from plants grown in greenhouse conditions. The melon plants were grown using commercial growing practices that included pruning and training to one vertical stem and the use of soilless media and drip fertigation. Wild type fruits were harvested at 37, 42, and 50 days after pollination (DAP), whereas transgenic fruits were harvested at 42, 50, and 56 DAP. TT fruits were harvested with that delaying period since their ripening process was slower than WT. Thirteen preharvest parameters were evaluated in transgenic and wild type fruits. Wild type and transgenic weight, lenght, width, soluble solids, tritatable acidity, pH, firmness, flesh thickness, seed cavity size and seed number parameters were not significantly different. Ethylene production and ACC oxidase from 42 DAP wild type fruits were greater than from transgenic fruits. Transgenic (ACC oxidase) galia melon fruits had a delayed fruit ripening process compared with wild type fruits.

Full textAbstract:
Interest in producing specialty melons (Cucumis melo) is increasing in Florida, but information on yield performance, fruit quality, and disease resistance of specialty melon cultivars grown in Florida conditions is limited. In this study conducted at Citra, FL, during the 2011 Spring season, 10 specialty melon cultivars were evaluated, in both certified organic and conventionally managed fields, including: Creme de la Creme and San Juan ananas melon (C. melo var. reticulatus), Brilliant and Camposol canary melon (C. melo var. inodorus), Ginkaku and Sun Jewel asian melon (C. melo var. makuwa), Arava and Diplomat galia melon (C. melo var. reticulatus), and Honey Pearl and Honey Yellow honeydew melon (C. melo var. inodorus). ‘Athena’ cantaloupe (C. melo var. reticulatus) was included as a control. ‘Sun Jewel’, ‘Diplomat’, ‘Honey Yellow’, and ‘Honey Pearl’ were early maturing cultivars that were harvested 10 days earlier than ‘Athena’. ‘Athena’ had the highest marketable yield in the conventional field (10.7 kg/plant), but the yield of ‘Camposol’, ‘Ginkaku’, ‘Honey Yellow’, and ‘Honey Pearl’ did not differ significantly from ‘Athena’. Under organic production, ‘Camposol’ showed a significantly higher marketable yield (8.3 kg/plant) than ‘Athena’ (6.8 kg/plant). ‘Ginkaku’ produced the largest fruit number per plant in both organic (10 fruit/plant) and conventional fields (12 fruit/plant) with smaller fruit size compared with other melon cultivars. Overall, the specialty melon cultivars, except for asian melon, did not differ significantly from ‘Athena’ in terms of marketable fruit number per plant. ‘Sun Jewel’, ‘Diplomat’, and ‘San Juan’ showed relatively high percentages of cull fruit. ‘Honey Yellow’, ‘Honey Pearl’, and ‘Sun Jewel’ exhibited higher soluble solids concentration (SSC) than ‘Athena’ in both organic and conventional fields, while ‘Brilliant’, ‘San Juan’, and ‘Ginkaku’ also had higher SSC than ‘Athena’ under organic production. ‘Honey Yellow’, ‘Sun Jewel’, ‘Brilliant’, and ‘Camposol’ were less affected by powdery mildew (caused by Podosphaera xanthii) and downy mildew (caused by Pseudoperonospora cubensis) in the conventional field. ‘Honey Yellow’ and ‘Camposol’ also had significantly lower aboveground disease severity ratings in the organic field compared with ‘Athena’, although the root-knot nematode (RKN) (Meloidogyne sp.) gall rating was higher in ‘Honey Yellow’ than ‘Athena’.

Melon hybrids (Mission, Bonus no 2, Don Carlos, Louis, Pacstart, PPAA, Don Domingos and Nero) were appraised in 23 environments, differentiated by the cultivation period (five periods), different cultive densities, soil covering with black polyethylene film or sliced sugar cane, presence or absence, and field conditions, low tunnel or greenhouse. Number of fruits, total and commercial production (TNF, CNF, TYF, CYF), mean weight, fruit size and length ratio of fruits (WMT, WMC, DMF, LR), net index (NI), refractometric index of juice (TSS) were analyzed. The experimental design was the randomized blocks with four replications. EBERHART & RUSSELL (1996) methodology was applied to obtain adaptability and stability parameters. Bônus no 2 and Nero presented the highest TNF, CNF, TYF and CYF, while Pacstart reached highest WMT, WMC and DMF. NI varied among hybrid ones and environments. SST was satisfactory for all hybrids ones (>9o brix); Don Carlos, Pacstart and PPAA obtained the smallest values. Environments with larger temperature and brightness were superior. Soil covering, low tunnel and greenhouse made possible the production in unfavorable environments. Larger densities influenced the production positively. The stability varied among hybrids (WMT, WMC< DMF, LR). The most productive hybrids were adapted to more favorable environments. The research evidenced the possibility of cultivation of netted melons at Jaboticabal-SP conditions.

Os experimentos foram conduzidos em casa de vegetação do Setor de Olericultura e Plantas Aromático-Medicinais da FCAV-UNESP, Jaboticabal-SP, com o objetivo de avaliar seis métodos de enxertia em melão rendilhado e seus efeitos na produtividade em três épocas de cultivo. Para o delineamento experimental, foram realizadas análises conjuntas das três épocas de cultivo (Época 1 – 21-08-2007 a 17-12-2007; Época 2- 10-03-2008 a 22-08-2008; Época 3 – 10-07-2008 a 27-11-2008) com os tipos de enxertia, mais a testemunha. Cada característica também foi avaliada separadamente, utilizando-se do delineamento de blocos ao acaso, com sete tratamentos e três repetições. Os tratamentos foram representados por dois métodos de enxertia utilizados no Brasil para cucurbitáceas: fenda cheia e encostia; quatro métodos da Coreia: palito, bisel, palito sem raiz e bisel sem raiz; e a testemunha que não foi submetida à enxertia. Após a realização das enxertias, as mudas permaneceram em câmara com alta umidade até o pegamento, quando foram transplantadas para casa de vegetação e tutoradas na vertical. Foram avaliadas as seguintes características: diâmetros do porta-enxerto e enxerto, área foliar em três fases do cultivo, número de internódios, produção, dimensão dos frutos e sólidos solúveis. Na Época 3, observaram-se as maiores médias na maioria das características avaliadas, e foi considerada a mais indicada para a condução de mudas enxertadas. O tipo de enxertia não influenciou na maioria das características avaliadas. As enxertias tipo fenda cheia, encostia, bisel e bisel sem raiz resultaram em mais de 90% de pegamento e são as mais indicadas para melão rendilhado, uma vez que não ocorreram doenças de solo. Não houve diferença na produtividade entre os métodos de enxertia e o pé-franco.
The works was carried in greenhouse at FCAV – UNESP, Jaboticabal – SP, Brazil, to evaluated six grafting methods in muskmelon and their effects on the productivity in three seasons cultivations.The experiment design was in randomized blocks with seven treatments and three replications. (Season 1: August 21th to December 21th 2007; Season 2: March 10th to August 22th 2008 and Season 3: July 10th to November 27th 2008). The treatments was two grafting methods utilized in Brazil to cucurbits: fenda cheia and encostia; four methods from Korea: hole insertion grafting, splice grafting, combination of root pruning and hole insertion grafting, and combination of root pruning and splice grafting, and the testimony, that not be grafted process. After the grafting process, the seedlings stayed inside the high humidity chamber until the success of grafting. After the evaluations of percent of grafting, the seedlings was moved to greenhouse. Was evaluated the caracteristics of fruits: diameter of rootstocks and scion, leave area, node number, yield, fruits dimensions and SST. The season 3, has the greatest medium on the most of caracteristics evaluateds and was considered the most indicated to seedlings grafted yield. The graftings methods didn’t influenced most of caracteristics evaluateds. The grafting methods of fenda cheia, encostia, splice grafting and combination of root pruning and splice grafting, arrived more than 90% of grafting success and they are the most indicated to muskmelon. Didn’t have diference on the yield to grafting methods and testimony.

Com o objetivo de avaliar o desempenho de híbridos experimentais de melão rendilhado em dois sistemas de cultivo e o desempenho de híbridos de melão rendilhado em diferentes substratos foram desenvolvidos dois experimentos no Setor de Olericultura e Plantas Aromático-Medicinais da UNESP, Jaboticabal, SP. O primeiro experimento foi desenvolvido de 20 de setembro de 2008 a 05 de janeiro de 2009. Foram avaliados seis híbridos experimentais, Jab 07#16, Jab 07#17, Jab 07#23, Jab 07#24, Jab 07#26, Jab 07#28, e três híbridos comerciais de melão rendilhado, Bônus nº 2, Louis e Fantasy, em dois sistemas de cultivo (em solo e em fibra da casca de coco), adotando-se o manejo recomendado para a cultura, em cada um dos sistemas. O delineamento experimental utilizado foi em blocos casualizados, com nove tratamentos e quatro repetições, para cada sistema de cultivo, realizando-se análise conjunta dos dados. Concluiu-se que, para o cultivo em fibra da casca de coco todos os híbridos são recomendados, exceto o Jab 07#17. No cultivo em solo recomendam-se os híbridos Bônus n° 2, Fantasy, Jab 07#26, Jab 07#28 e Jab 07#16. No segundo experimento foram avaliados cinco substratos (S1 = fibra da casca de coco; S2 = areia; S3 = ½ areia e ½ bagaço de cana-de-açúcar; S4 = ½ areia e ½ casca de amendoim; e S5 = areia, bagaço de cana-de-açúcar e casca de amendoim), e quatro híbridos de melão rendilhado (Bônus n° 2, Louis, Fantasy e Jab 2007#16). Utilizaram-se vasos plásticos de 13 dm3 que foram dispostos no espaçamento de 1 m entre fileiras e 0,5 m entre vasos. O delineamento experimental foi em blocos casualizados, em esquema fatorial 5 x 4, com quatro repetições.

Aiming evaluate the net melon experimental hybrids in two crop systems as well the net melon hybrids performance in different substrates were carried out two experiments in the Setor de Olericultura e Plantas Aromático-Medicinais da Faculdade de Ciências Agrárias e Veterinárias (UNESP-Jaboticabal Vegetables and Aromatic- Medicinal Plants Sector). The first experiment was carried out from Sept-20-2008 to Jan- 05-2009, where were evaluated six experimental hybrids (Jab 07#16, Jab 07#17, Jab 07#23, Jab 07#24, Jab 07#26, and Jab 07#28) and three commercial hybrids (Bônus nº 2, Louis, and Fantasy), in two crop systems (soil and coconut fiber cropping), adopting the recommended management to the melon crop in each of the two crop systems. The experimental design used was the randomized blocks with nine treatments and four replications to each cultivation system. The both experiment data analysis was done joint. Productive and qualitative fruit characteristics were evaluated and, based on the results, the crop system under coconut fiber all hybrids are recommended, except the hybrid Jab 07#17, while only the hybrids Bônus n° 2, Fantasy, Jab 07#26, Jab 07#28, and Jab 07#16 should be cultivated in the conventional (soil) system. In the second experiment were evaluated five substrates (S1= coconut fiber; S2= sand; S3= ½sand + ½sugar cane bagasse; S4= ½sand + ½peanut fiber; and S5= sand + sugar cane bagasse + peanut fiber in four net melon hybrids - Bônus n° 2, Louis, Fantasy, and Jab 2007#16). Plastic pots of 13dm3 each were filled up with each substrate and spaced 1m between lines and 0.5m between plots. The experimental design used was the randomized blocks, in a 5x4 factorial scheme and four replications. The fruit productive and qualitative characteristics were evaluated and based on the results, the best substrate option to cultivate net melon is the 50%sand + 50% peanut fiber...

Sabe-se que nos últimos 100 anos a concentração de CO2 na atmosfera vem aumentando devido ao aumento da atividade do homem em emitir mais de 8 bilhões de toneladas anuais de gás carbônico. Pensando no que isso poderia representar para as plantas, nas últimas décadas se intens ificaram os estudos com aplicação de CO2 nas plantas via ambiente e via água. Freqüentemente foram observados aumentos em crescimento de produção sob elevadas concentrações de CO2 na atmosférica. O melão tem se constituído em ótimo negócio para o Nordeste brasileiro. O Brasil passou a destacar-se no cenário internacional, embora com registros de quedas nas exportações nos últimos anos. Procurando-se melhorar os estudos com aplicação gás carbônico CO2 com o intuito de torna viável a aplicação, ou seja, diminuir a relação Custo/Benefício procurou-se diminuir número de aplicações e o volume de CO2 por ha -1 mantendo-se a produtividade daquelas aplicadas durante todo o ciclo. O objetivo deste trabalho foi estudar o efeito de uma dose de (CO2) em diferentes fases fenológico da cultura do melão aplicadas via água de irrigação por gotejamento subsuperficial, na, qualidade, produtividade, do meloeiro cultivado em ambiente protegido. Para isso, foi conduzido um experimento em duas estufas de 112 m 2 cada, estudando-se o efeito na aplicação de CO2 aplicada via água de irrigação no florescimento, na frutificação e no florescimento mais frutificação, além de uma testemunha na qual não houve aplicação de CO2. O delineamento experimental para o efeito das épocas foi o de blocos casualizados , com quatro repetições. A irrigação foi realizada utilizando-se o sistema de irrigação por gotejamento, sendo estes enterrados a 15cm de profundidade, e manejados por tensiômetros. A aplicação do gás foi realizada por intermédio de um cilindro de CO2 comercial e injetadas por diferença de pressão, durante o tempo necessário à aplicação da dose pré-estabelecida. Os resultados obtidos revelaram que a aplicação de CO2 via água de irrigação para os tratamentos na frutificação (T3) e florescimento (T1) proporcionou aumentos de 18%,17% em relação ao tratamento sem CO2 (T4), o menor incremento foi de 8,8% do T2 em relação ao T4.It is known that in the last 100 years the carbon dioxide (CO2) concentration in the atmosphere is increasing due to the increase in human activity in emitting more than eight million tons yearly of carbon dioxide. Thinking on what this could mean for plants, studies had intensified in the last decades with CO2 application to plants through environment and water. Freq uently, increases in yield were observed under high CO2 concentration at atmosphere. Melon is turning into a big business for the northeast of Brazil. Brazil starts to stand out at the international scenery, beside records of export dropping in the last years. Trying to improve the studies with CO2 application, to minimize the cost benefit relationship and this way make it viable economically by diminishing the number of application and volume of CO2 per hectare maintaining the yield obtained by those applied through out year. The objective of this work was to study the effect of one single rate of CO2 applied at different crop stages through water by a subsurface drip irrigation system, at the yield and quality, of melon cultivated in greenhouse. For that, an experiment was led in two greenhouses of 112 m 2 each, being studied the effect of CO2 applied at flowering, at fruiting, and at flowering plus fruiting, besides an untreated plot with no application of CO2. The experimental design was for timing was randomized blocks with four replications. Irrigation was realized by a subsurface dripping irrigation system, which was positioned at 15 cm depth, and managed by tensionmeters. The CO2 injection, was provided by a commercial cylinder, and was done by pressure differential. Application time was that one the necessary time to apply the pre -established rate. Obtained data showed that the application of CO2 through irrigation water for the fruiting (T3) and flowering (T1) treatments provided yield increases of 18% and 17% respectively when compared to untreated (T4), the lowest yield increment was obtained by flowering plus fruiting (T2) compared to untreated.

Central Queensland University. Biological and Environmental Science, 2005. http://library-resources.cqu.edu.au./thesis/adt-QCQU/public/adt-QCQU20051019.144749.
Full textAbstract:
Total soluble solids (TSS) is a reliable indicator of melon eating quality, with a minimum standard of 10% recommended. The state of Australian melon production with respect to this quality criterion was considered within seasons, between growing districts and over seasons. It was concluded that improvement in agronomic practice and varietal selection is required to produce sweeter melons. The scientific literature addressing melon physiology and agronomy was summarised, as a background to the work that is required to improve melon production practices in Australia.
The effect of source sink manipulation was assessed for commercially grown and glasshouse grown melon plants. The timing of fruit thinning, pollination scheduling, the application of a growth inhibitor and source biomass removal were assessed in relation to fruit growth and sugar accumulation. Results are interpreted against a model in which fruit rapidly increase in weight until about two weeks before harvest, with sugar accumulation continuing as fruit growth ceases. Thus treatment response is very dependant on timing of application. For example, fruit thinning at 25 days before harvest resulted in further fruit set and increased fruit weight but did not impact on fruit TSS (at 9.8%, control 9.3%), while thinning at 5 days before harvest resulted in a significant (Pless than 0.05) increase in fruit TSS (to 10.8%, control 9.3%) and no increase in fruit weight or number. A cost/ benefit analysis is presented, allowing an estimation of the increase in sale price required to sustain the implementation of fruit thinning.
The effect of irrigation scheduling was also considered with respect to increasing melon yield and quality. To date, recommended practice has been to cause an irrigation deficit close to fruit harvest, with the intent of 'drying out' or 'stressing' the plant, to 'bring on' maturity and increase sugar accumulation. Irrigation trials showed that keeping plants stress-free close to harvest and during harvest, facilitated the production of sweeter fruit.
The maintenance of a TSS grade standard using either batch based (destructive) sampling or (non-invasive) grading of individual fruit is discussed. On-line grading of individual fruit is possible using near infrared spectroscopy (NIR), but the applicability of the technique to melons has received little published attention. Tissue sampling strategy was optimised, in relation to the optical geometry used (in commercial operation in Australia), both in terms of the diameter and depth of sampled tissue. NIR calibration model performance was superior when based on the TSS of outer, rather than inner mesocarp tissue. However the linear relationship between outer and middle tissue TSS was strong (r2 = 0.8) in immature fruit, though less related in maturing fruit (r2 = 0.5). The effect of fruit storage (maturation/senescence) on calibration model performance was assessed. There was a negligible effect of fruit cold storage on calibration performance.
Currently, the agronomist lacks a cost-effective tool to rapidly assess fruit TSS in the field. Design parameters for such a tool were established, and several optical front ends compared for rapid, though invasive, analysis. Further, for visualisation of the spatial distribution of tissue TSS within a melon fruit, a two-dimensional, or hyper-spectral NIR imaging system based on a low cost 8-bit charge coupled device (CCD) camera and filter arrangement, was designed and characterised.

In this work the extraction of substances from the common melon (Cucumis melo var. Acidulus) was carried out, which has more specific application in both, the food industry, as in the pharmaceutical and cosmetic industry, becoming more valuable than the fruit in natura. The objective of this study was to extract, quantify, characterize and modify chemically by sulfation pectin the common melon (Cucumis melo var. acidulus). The extractions were performed in neutral, acidic and basic conditions, with yields of 8%, 10.8% and 14%, respectively. In addition to the Elementary Analysis, pectin extracted with acid, it was characterized by nuclear magnetic resonance of carbon (13C NMR) and Hydrogen (1H NMR), Potentiometric Titration,
Spectroscopy in the Infrared (FT-IR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), hermogravimetric Analysis (TGA), Differential Scanning Calorimetry
(DSC), Gel Permeation Chromatography (GPC), Rheology and Zeta Potential. Some of these analyzes were not performed for samples extracted in alkaline, neutral and sulfated acid, as well as for commercial use sample, for which the analysis depended on the purpose for which it was
proposed, is it to determine a specific feature the material and the degree of esterification (DE)
or to identify overall change in polymer structure such as sulfation. The 13C-NMR showed
peaks characteristic of galacturonic acid. The FT-IR and potentiometric titration permitted the calculation of the degree of esterification (DE) of acidic, basic, neutral and sulfated samples and also a commercial sample from Sigma Aldrich; GE results of the samples obtained by these techniques were compared, showing that the samples are acidic and neutral low GE. The result of GE acid sample was also obtained by 1H NMR, confirming its low GE condition. The SEM of the sample showed particles with acidic spherical structure with surface flattening, typical drying spray dried, suggesting potential application in drug encapsulation. The XRD revealed that the material has amorphous character, an increase of crystallinity after chemical modification. The TGA technique revealed the pectin degradation in three stages. The DSC curve showed an endothermic peak at 150 ÂC and an exotherm at 245ÂC for the loss of water and the main step of breakdown of the material, respectively. The molecular weight of the acid sample, determined by GPC, showed values of typical polymeric materials 4.5 x 105 g/mol, consistent with pectins. The rheological study revealed the shear-thinning property of pectin solution.Neste trabalho foi feita a extraÃÃo de substÃncias presentes no melÃo caipira (Cucumis melo var. acidulus) que tenham aplicaÃÃo mais especÃfica tanto na indÃstria alimentÃcia, quanto na indÃstria farmacÃutica e cosmÃtica, sendo, portanto, de maior valor comercial que os frutos in natura.

O FT-IR e a TitulaÃÃo PotenciomÃtrica permitiram o cÃlculo do Grau de EsterificaÃÃo (GE) das amostras Ãcida, bÃsica, neutra, sulfatada e tambÃm de uma amostra comercial da Sigma Aldrich; o resultado de GE das amostras, obtidos por essas tÃcnicas, foram comparados entre si, mostrando que as amostras Ãcida e neutra sÃo de baixo GE.O resultado de GE da amostra Ãcida tambÃm foi obtido por RMN 1H,confirmando sua condiÃÃo de baixo GE. O MEV da amostra Ãcida revelou partÃculas com estrutura esfÃrica com achatamentos superficiais, tÃpicos de secagem em spray dried, sugerindo potencial aplicaÃÃo em encapsulaÃÃo de fÃrmacos. A DRX revelou que o material apresenta carÃter amorfo, com aumento de cristalinidade apÃs modificaÃÃo quÃmica. A tÃcnica de TGA revelou os estÃgios de degradaÃÃo da pectina em trÃs etapas. A curva de DSC apresentou um pico endotÃrmico em 150 ÂC e um exotÃrmico em 245 ÂC, relativos à perda de Ãgua e à principal etapa de degradaÃÃo do material, respectivamente. A massa molecular da amostra Ãcida, determinada por GPC, apresentou valores tÃpicos de materiais polimÃricos 4,5 x 105 g/mol, condizentes com pectinas.

Mestrado em Engenharia Agronómica - Instituto Superior de AgronomiaThe main goal of this study was comparing traditional low density black polyethylene plastic mulch (25μm) with three different starch based biodegradable mulch films (15μm), on a muskmelon “Lusitano” (Cucumis melo var. inodorus). The mulch film layout and crop plantation, soil temperature and humidity, weeds, canopy spread area, flowering and yield and crop quality were monitored. The field trial was conducted in Azeitada – Almeirim (from April to July 2011) with a completely randomized experimental design with three replications, 25 plants each. The mulch films modalities were: PE (control), BMF1 (black biodegradable plastic film Mater-Bi®-CF04P); BMF2 (black biodegradable plastic film Mater-Bi®-CF04P with recycled material) and BMFV (green biodegradable plastic film Mater-Bi®-CF04P). The results showed the adaptability of biodegradable mulch films to climatic conditions and traditional techniques applied, not observing significant differences in fruit quality and production. Regarding the soil water content the BMF1 showed higher values when compared with BMFV, as well as BMFV compared with PE. The soil temperatures were similar in all the modalities and PE and BMFV had precocious flowering and production. A positive correlation between initial growth (36DAT) and the soil growing degree-days (temperature 10ºC) accumulated was obtained, and also between initial growth and final yield.
