Full textAbstract:
Citrulline has been recently shown to behave as a novel compatible solute in the <i>Citrullus lanatus</i> (<i>Cucurbitaceae</i>) growing under desert conditions. In the present study we have investigated some aspects of the relationship which might occur in leaves of melon seedlings, also known to produce citrulline, between the capacity to accumulate this ureido amino acid and salt tolerance. With this end in view, salt-induced changes at the citrulline level have been compared in two melon genotypes exhibiting contrasted abilities to withstand the damaging effects of high salinity. Progressive salinization of the growing solution occurred at 23 days after sowing. The final 250 mmol/l external NaCl concentration was reached within 5 days and further maintained for 16 days. In response to this treatment, it was found that the citrulline amount increased in fully expanded leaves of both genotypes according to different kinetics. The salt tolerant genotype Midyat was induced to accumulate citrulline 4 days before the salt sensitive Yuva and as a consequence the final amount of this amino acid was twice higher in the former than in the latter. Compared with citrulline, the free proline level was found to be relatively low and the changes induced in response to the salt treatment exhibited different trends according to the genotypes under study. Thus at the end of the treatment mature leaves of the salt sensitive Yuva contained higher amount of proline than those of Midyat. The changes in the calculated molar ratio between citrulline and free proline suggested that salt tolerance might be associated with high values for this ratio and vice et versa for sensitivity. The interest of citrulline as a biochemical marker for salt tolerance of melon genotypes is discussed.

Full textAbstract:
This study sought to investigate the cardioprotective potency and interaction of muskmelon (Cucumis melo) with enalapril (ENA) against myocardial damage caused by acute and chronic isoprenaline (ISO) treatments in rats. In the acute model, 150 mg/kg (s.c) of ISO was administered for two consecutive days at the end of pretreatment with either ENA, muskmelon, or both in their respective groups. ISO was introduced into the chronic therapy of ENA/muskmelon/ENA + muskmelon groups during the last 10 days at 3 mg/kg. Muskmelon was tested at three doses (100, 200, and 500 mg/kg, p.o., 30 days), and one normal dose of ENA (10 mg/kg) was used. Blood samples were taken at the end of treatment, and the animals were sacrificed. Biochemical markers such as LDH and CK-MB, as well as antioxidant (superoxide dismutase (SOD) and catalases) and thiobarbituric acid reactive species (TBARS) were measured in both serum and heart tissue homogenate (HTH). To confirm the biochemical findings, histological slides of heart tissue were prepared. ISO administration induced an elevation in the amount of TBARS, which was increased in all groups in which it was administered. Prior treatment with muskmelon and ENA in animals resulted in a rise in biomarker activity in homogenated heart tissue and a decrease in serum. In terms of alleviating the abnormal conditions caused by ISO, the group given a high dose of muskmelon and combined therapy had the best outcomes. The activities of SOD and catalase were substantially higher in the treated classes. Histological findings showing the cytoprotective actions of the high dose of muskmelon and ENA have confirmed the biochemical outcomes of both models. It is therefore concluded that the high dose of muskmelon (500 mg/kg) has a promising cardioprotective potential that is improved more efficiently in the acute injury model in the presence of ENA.

Introduction: Kidney stones are the 3rd major health problem affecting the urological system. Industrial chemical ethylene glycol can generate calcium oxalate crystals in kidneys. Allopurinol has been used to treat the hyperuricemia but can be effective against calcium oxalate kidney stones too. Seeds of Cucumis melo were traditionally utilized as antioxidant and diuretic, so can be studied as litholytic agent against stones as well. Aims & Objectives: To assess and compare the litholytic effect of ethanolic extract of Cucumis melo seeds against ethylene glycol induced urolithiasis with allopurinol in rats. Place and Duration of study: This experimental study was conducted in Pharmacology Department of FPGMI, Lahore for the period of 2 months. Material & Methods: Four groups of 10 rats in each group were made. Calcium oxalate urinary stones were induced by 0.75% ethylene glycol for 28 days in male rats. Groups 1&2 served as negative and positive control while experimental groups 3&4 received Allopurinol 50mg/kg and Cucumis melo seed’s ethanolic extract (EECMS) in dose of 400mg/kg from 15th day to 28th day respectively. At the end of study, kidney weight, urinary calcium, oxalate and phosphorus along with histological examination of kidneys were used as measuring criteria of litholytic effect of seeds of Cucumis melo and was compared to allopurinol. Data analysis was performed using SPSS 20.0 & presented in mean±s.d .Post-hoc Tukey’s test and ANOVA were used for comparison between data groups Results: After 13 days of treatment experimental groups Groups 3 (Allopurinol 50mg/kg) and 4 (EECMS 400mg/kg) showed remarkable decreased mean urinary calcium, oxalate, phosphorus levels( mg/dl) and kidney weights(gm) of urinary calcium(10.55±1.53, 8.28±1.42), oxalate (18.3±0.78, 17.58±1.38), phosphorus (4.3±0.85, 3.59±1.49) and reduced kidney weights(1.43±0.22, 1.37±0.29) respectively(p value <0.001) as compared to diseased control group 2. Thus exhibiting Cucumis melo seed’s ethanolic extract has better litholytic role than allopurinol which also proved to be efficacious. Histopathological examination of kidney also showed dissolution of calcium oxalate stones. Conclusion: Seeds of Cucumis melo extract have better litholytic effect on calcium oxalate kidney stones than allopurinol with improvement noted in the renal histological profile.

Full textAbstract:
The southern root-knot nematode, Meloidogyne incognita [(Kofoid & White) Chitwood], causes serious economic losses to melon (Cucumis melo L.) production in the United States. The present study was conducted to determine if separable differences in nematode resistance of Cucumis melo could be found at some inoculum level. Five C. melo lines were compared with Cucumis metuliferus Naud. (C701A), a highly resistant species, for root necrosis, galling, egg mass production, and reproduction when inoculated at 0, 500, 1000, 2000, or 5000 nematode eggs per plant. Using these criteria, melon line C880 inoculated with 1000 eggs per plant was highly susceptible, while PI140471, PI 183311, and the cultivars Chilton, Georgia 47, Gulf Coast, Planters Jumbo, and Southland were less susceptible. In greenhouse tests with an inoculum level of 1000 eggs per plant, low levels of resistance were evident. A thorough screening of the available germplasm against M. incognita may identify higher levels of root-knot nematode resistance for incorporation into improved melon cultivars.

Full textAbstract:
This study aimed to analyze the details of collection of floral resources (pollen and nectar) by honeybees (Apis mellifera) on male and hermaphrodite flowers of melon (Cucumis melo). The experiments were conducted in areas located at Embrapa Semiárido and Embrapa Produtos e Mercado, Petrolina, state of Pernambuco, in November and December 2011, with crop of a hybrid yellow 10/00 F1 melon. Honeybee colonies housed in Langstroth hives, uniform concerning the number of individuals and brood area were used. The four experimental areas (0.5 ha each), received respectively 0, 1, 2 and 3 hives, from the first day on which the hermaphrodite flowers appeared to the end of the flowering period of the melon crop. The results showed that the bees visited more the hermaphrodite than the male flowers, in order to collect the resources (pollen and nectar), in all areas where honeybee hives were placed. In general, independently from the number of hives, the resource most collected was nectar. Pollen collection occurred mainly at the first hours of the morning, while nectar was collected throughout the day.

Full textAbstract:
AbstractEgg masses of Meloidogyne arenaria race 2 were observed on the second planting of oriental melon by the time of its first harvest under glasshouse conditions in Korea. Time and degree-days above 5°C (DD5) for egg mass formation after April were about 24.5 days and 500 DD5. Higher mean soil temperature shortened the days required for egg mass formation. A threshold temperature for degree-days accumulation of 12.2°C was selected on the basis of lowest coefficient of variation among data sets of time to egg mass formation. We propose the use of DD12.2 for predicting the time to egg mass formation of M. arenaria under these glasshouse conditions.

The leafminer Liriomyza sativae Blanchard is an important insect pest on melon crops in Brazil. However, the information about its biology on melon (Cucumis melo L.) is scarce. Therefore, the aim of this research was to know some biological aspects of this pest, reared on melon plants, under laboratory conditions at 25°C. Our results showed that the biological cycle of L. sativae lasts 15.9±0.04 days (egg-adult), namely: egg (2.7±0.01 days), larva (4.1±0.03 days) and pupa (9.1±0.03 days). The sex ratio is 0.51 and the females live (19.3±1.09 days) longer than males (16.2±0.96 days). These results can help in the integrated management of L. sativae on melon crops and improve the systems for rearing this leafminer in laboratory.

Resumo: O presente trabalho teve como objetivo avaliar o desempenho de híbridos de melão rendilhado cultivados em fibra da casca de coco reutilizada com fertirrigação, em ambiente protegido. O experimento foi conduzido em casa de vegetação em (FCAV-UNESP) Jaboticabal, Estado de São Paulo, Brasil, de março a julho de 2008. Utilizou-se o delineamento em blocos casualizados, em esquema fatorial 2x3, com quatro repetições. Os tratamentos resultaram da combinação de dois híbridos: 'Bônus no 2' e 'Fantasy', e três tipos de utilização de substrato (S1 = fibra da casca de coco nova; S2 = fibra da casca de coco utilizada uma vez na cultura do pimentão, e S3 = fibra da casca de coco utilizada por duas vezes: 1a na cultura do pimentão e 2a na cultura do melão). O cultivo foi realizado em vasos plásticos de 13 dm3 e dispostos em fileiras duplas, nos espaçamentos de 0.8 m entre fileiras simples, 0.5 m entre plantas na linha e 1.10 m entre fileiras duplas. Foi utilizada irrigação por gotejamento com solução nutritiva recomendada para a cultura. Após a colheita, avaliaram-se: diâmetro transversal do fruto, diâmetro longitudinal do fruto, índice de formato de fruto, diâmetro transversal do lóculo, diâmetro longitudinal do lóculo, índice de formato do lóculo, diâmetro da inserção do pedúnculo, espessura do mesocarpo, firmeza, rendilhamento da casca, massa do fruto, sólidos solúveis, acidez titulável, pH e produtividade. Foi realizada a diagnose foliar e acaracterização físico-química do substrato. Concluiu-se que, para as características produtivas e qualitativas dos frutos não houve diferenças entre os híbridos de melão rendilhado; a reutilização por até três vezes não afetou o desempenho dos híbridos; a reutilização promoveu, nos substratos, acúmulo de nutrientes, aumento da densidade e volume de água facilmente disponível, redução do espaço de aeração e porosidade totalAbstract: The present work had as objective to evaluate the performance of net melon hybrids cultivated in reused coconut fiber substrate with fertigation, in protected environment. The experiment was carried out in greenhouse at (FCAVUNESP) Jaboticabal, São Paulo State, Brazil, from March to July 2008. The experimental design was randomized complete block design, in 2x3 factorial scheme, with four replications. The treatments resulted of the combination of two net melon hybrids: 'Bônus no 2' and 'Fantasy' and three types of substrate (S1 = new coconut fiber; S2 = coconut fiber used once, in the culture of sweet pepper; and, S3 = coconut fiber used twice, 1st in the culture of sweet pepper and 2 nd in the culture of the net melon). The cultivation of net melon was carried out in plastic pots of 13 dm3 containing coconut fiber, were arranged in spacing of 0,8 m between simple rows, 0,5 m between plants in rows and 1,10 m between double rows. It was used drip irrigation with nutrient solution recommended to the culture. After harvest were evaluated: transverse fruit diameter, longitudinal fruit diameter, index of fruit shape, transverse locules diameter, longitudinal locules diameter, index of locules shape, diameter of peduncle insertion, pulp thickness, firmness, skin netting, mass of fruit, soluble solids; titratable acidity, pH, productivity. Leaf diagnosis and physical-chemical characterization of substrate were carried out. Concluded that for the productive and qualitative characteristics of fruits there wasn't observed differences between net melon hybrids; the reuse of three times didn't affect the performance of net melon hybrids; the reuse of three times caused in the substrate, accumulation of nutrients, an increasing of bulk density and easily available water content, decreasing of the total porosity and aeration space

Resumo: Este trabalho avaliou as alterações bioquímicas, fisiológicas, microbiológicas e sensoriais de produtos minimamente processados (PMP) de melão e melancia, utilizando diferentes cortes, embalagens e temperaturas de armazenamento. Melancias 'Crimson Sweet', originárias região de Marília, SP, foram processadas no Laboratório de Tecnologia dos Produtos Agrícolas da UNESP-Jaboticabal, enquanto que melões tipo Orange Flesh, de Mossoró, RN, foram processados no Laboratório de Fisiologia e Tecnologia Pós-Colheita da Embrapa Agroindústria Tropical em Fortaleza, CE. Os frutos depois de lavados com detergente neutro, enxaguados, imersos em água clorada (200mg.L-1) e armazenados em câmara fria (10ºC), por doze horas, tinham a polpa higienicamente cortada em cubos (2,5cm de aresta) e fatias (2,5cm x 2,5cm x 5,0cm), acondicionadas em embalagens plásticas com tampa, copo ou bandeja, ambas de PET, que eram armazenadas a 3ºC e 6ºC. O rendimento da melancia e do melão em PMP foi, respectivamente, de 29-40% e 38-42% em relação ao fruto inteiro. O PMP destes frutos mostrou, nas primeiras 3 horas, aumento na atividade respiratória, que se reduziu e estabilizou, até o final do armazenamento. Isto levou o conteúdo de O2 nas embalagens a se reduzir e o de CO2 a aumentar, durante o armazenamento. A vida útil destes produtos, limitada pela aparência, foi de cinco e sete dias, respectivamente, para a melancia e o melão. A massa fresca, a coloração, a textura, as qualidades sensorial e microbiológica, o pH e os teores de ácido ascórbico, acidez total titulável, sólidos solúveis totais, açúcares solúveis e redutores, mostraram variações pouco expressivas.Abstract: This work aimed to evaluate the biochemical, physiological, microbiological and sensorial quality of melon and watermelon fruits minimally processed (MP), using different cutting types, packages and storage temperatures. 'Crimson Sweet' watermelons from orchards of Marília, SP were processed at the Laboratório de Tecnologia dos Produtos Agrícolas da UNESP-Jaboticabal, while type Orange Flesh melons from Mossoró, RN were processed at the Laboratório de Fisiologia e Tecnologia Pós-Colheita da Embrapa Agroindústria Tropical em Fortaleza, CE. Fruits after washing with neutral detergent, rinsed and dipped in chlorinated water (200 mg.L-1) were stored at 10oC, in previously hygienized chamber, for 12 hours. The flesh was hygienically cut in cubes (2,5 cm) and slices (2,5 x 2,5 x 5,0 cm), and conditioned in plastic packages, glass or tray with lids, a made of polyethylene terephthalate (PET), and stored at 3oC and 6oC. Watermelon and melon yield in fruits MP were 29-37% and 38-42%, respectivelly, in relation to whole fruit. These fruits MP showed, in first 3 hours, increase in respiratory rate followed by reduction and stabilization until the end of storage. The effect was a reduction of O2 and an increase of CO2 content inside the packages, during storage. The shelf life of these products were five and seven days, respectivelly for watermelon and melon, with appearance development as the limiting factor. The fresh weight loss, color, firmness, sensorial and microbiological qualities, pH and content of ascorbic acid, total titratable acidity, soluble solids, soluble and reducing sugars, showed variations with little significance.

Resumo: O fósforo é um dos nutrientes mais importantes para a cultura do meloeiro, que influencia significativamente a economia da região Nordeste. Assim, o objetivo deste trabalho foi avaliar o efeito da aplicação de doses de P na produção e qualidade de frutos de melão amarelo, cultivar Goldex F1. O experimento foi desenvolvido no Colégio Agrícola de Teresina/UFPI, entre maio e agosto de 2008. O delineamento experimental foi montado em 4 blocos casualizados em parcelas (tratamentos principais), com doses de P (0, 120, 240, 360 e 480 kg ha-1 de P2O5); as parcelas foram subdivididas no tempo (tratamentos secundários) aos 20, 27, 34, 41 e 48 dias após o transplante (DAT). Nas condições de cultivo do meloeiro em Teresina, a aplicação de doses de P2O5: 1 - A produção de frutos comerciais, massa e número de frutos comerciais por planta, diâmetro, comprimento e espessura da polpa de frutos comerciais aumentaram até a dose de 278 kg/ha P2O5; 2 - Doses acima de 278 kg/ha P2O5 prejudicaram o desenvolvimento inicial das plantas e a produção de frutos comerciais por planta; 3 - As doses de fósforo não influenciaram no teor de sólidos solúveis e acidez titulável dos frutos comerciais
Abstract: Phosphorus is a important nutrient for the melon, and this culture has significant importance for the economy in the Northeast of Brazil. Thus, the purpose of this study was to evaluate the effect of P levels on production and fruit quality of yellow melon variety Goldex F1. The experiment was conducted at the Agricultural College Teresina / UFPI between May and August 2008. The experiment was arranged in randomized blocks with five main treatments (P doses (0, 120, 240, 360 and 480 kg P2O5 ha-1) were subdivided in time (secondary treatment) at 20 , 27, 34, 41 and 48 days after transplanting (DAT). The results showed, under the conditions of this experiment, that: 1 - The productivity of comertial fruits, weight and number of comertial fruits per plant, as well as lengh and diameter of fruits and thickness of pulp increased with doses until 278 kg/ha P2O5; 2 - Doses above 278 kg/ha P2O5 tended to decrease initial planta development and production of fruit production; 3 - The phoshporus doses used do not affected significantly soluble solids and acidity of comercial fruits

Foram realizados 4 experimentos: 1 e 2 - frutos de melão Cantaloupe e Pele de Sapo provenientes de Baraúna/RN e Juazeiro/BA, respectivamente; 3 e 4 - frutos de melão Cantaloupe e Gália provenientes da região de Cartagena (Espanha). Após a colheita, os frutos dos experimentos 1 e 2 foram transportados ao Laboratório de Frutas e Hortaliças da Faculdade de Ciências Agronômicas - UNESP - Botucatu/SP, e os dos experimentos 3 e 4 transportados para o Laboratório de Postrecolección e Refrigeración da Universidad Politécnica de Cartagena/Espanha. Após o processamento manual (corte em seções trapezoidais) os melões MP (minimamente processados) dos experimentos 1 e 2 foram acondicionados em embalagens de poliestireno expandido recobertas com filme de polietileno e irradiados nas doses: 0,0kGy; 0,1kGy; 0,2kGy; 0,3kGy; 0,4kGy e 0,5kGy. Os melões MP dos experimentos 3 e 4, após o processamento, foram imersos durante 1 minuto a 5ºC em: água (testemunha); vanilina (1000 mg L-1 e 2000 mg L-1); ácido cinâmico (148,16 mg L-1 e 296,32 mg L-1) e outros dois tratamentos consistiram em aplicação de vapor de ácido cinâmico (148,16 mg L-1 e 296,32 mg L-1) nos melões MP dentro da embalagem (bandejas de polipropileno termo seladas com filme de polipropileno). O armazenamento refrigerado foi realizado durante 10 dias 5±1ºC e 85-90% UR (experimentos 1 e 2) e à 5±1ºC e 85-95% UR (experimentos 3 e 4). As alterações na qualidade foram detectadas por meio das análises: perda de massa fresca, conservação pós-colheita, firmeza, pH, acidez titulável, sólidos solúveis, teores de açúcares redutores e redutores totais, ácido ascórbico, vitamina C, taxa respiratória, produção de etileno...

Abstract: The aim of this research was to evaluated the effects of the gamma radiation and the natural antimicrobials in the conservation of fresh-cut melon storaged under refrigeration. Four experiments were accomplished: 1 and 2 - the varieties used were 'Cantaloupe' and 'Pele de Sapo' from Baraúna/RN and Juazeiro/BA, respectively; 3 and 4 - the varieties used were 'Cantaloupe' and 'Gália' from Cartagena (Spain). After harvesting, fruits from experiment 1 and 2 were sent to the Laboratory of Fruits and Vegetables at the University of Sao Paulo State (UNESP - Botucatu/SP). Fruits from experiment 3 and 4 were sent to the Postharvest and Refrigeration Group at the Technical University of Cartagena/Spain. After the manual processing (cut in trapezoidal sections) the fresh-cut melons of the experiment 1 and 2 were conditioned in polystyrene trays involved by polyethylene film and irradiated with doses: 0,0kGy; 0,1kGy; 0,2kGy; 0,3kGy; 0,4kGy and 0,5kGy. After processing, fresh-cut melons from experiment 3 and 4 were immersed for 1 min at 5ºC in water (control); vanillin (1000 mg L-1 and 2000 mg L-1); cinnamic acid (148,16 mg L- 1 and 296,32 mg L-1). Two additional treatments consisted on the application of cinnamic acid vapor (148,16 mg L-1 e 296,32 mg L-1) on fresh-cut melons within the packages (polypropylene trays heat-sealed with polypropylene). The storage was realized during 10 days in a cold camera to 5±1ºC and 85-90% HR (experiment 1 and 2) and to 5±1ºC and 85- 95% HR (experiment 3 and 4). The quality alterations were detected through the analyses: loss of fresh mass, postharvest conservation, firmness, pH, acidity titratable, soluble solids, reducing and total reducing sugar content, ascorbic acid, vitamin C, respiration rate, ethylene production, gas composition (CO2 and O2), enzymes activity (peroxidase, polygalacturonase and pectinmethylesterase), antioxidant...

Resumo: Melhores condições de higiene, diminuição na incidência de doenças do solo e alternativa para a falta de espaço são as principais vantagens que o produtor encontra na utilização de recipientes para o cultivo de hortaliças em estufas. Esse trabalho teve como objetivo avaliar diferentes tipos de recipientes com substrato de fibra de coco para o cultivo de melão rendilhado, com uso da fertirrigação sob ambiente protegido. O ensaio foi conduzido de março a junho de 2006 na área experimental da Fazenda de Ensino, Pesquisa e Extensão da Faculdade de Engenharia - UNESP, Campus de Ilha Solteira - SP. Os tratamentos constaram de quatro recipientes (Calha com capilaridade, Calha com gotejamento, Vaso pequeno e Vaso grande) e dois híbridos de melão rendilhado (Laurent e Maxim). O delineamento experimental adotado foi o de blocos ao acaso com 4 repetições. Cada parcela foi constituída por 12 plantas, sendo 6 plantas de cada híbrido, com espaçamento de 1,3m entre fileiras e 0,5m entre plantas. Após as avaliações, os dados foram submetidos à análise de variância e teste de tukey, ao nível de 5% de probabilidade, com auxílio do programa computacional Sanest. Avaliou-se condutividade elétrica (CE), número de folhas, altura das plantas, número médio de frutos por planta, número de frutos totais, massa média de frutos, produtividade total, produção de frutos graúdos, médios e miúdos, diagnose foliar (macro e micro nutrientes) e teor de sólidos solúveis totais (SST). Os recipientes vaso grande, vaso pequeno e calha com gotejamento proporcionaram valores semelhantes e superiores para número de frutos por planta, número de frutos totais, produção de frutos graúdos e massa média, porém o vaso grande apresentou maior produtividade total, enquanto a calha com capilaridade proporcionou os menores valores para quase todas as avaliações mostrando-se inferior aos ...(Resumo completo,
Abstract: Better hygiene conditions, less incidence of soil diseases and alternative to lack of space are the main advantages the producer finds in greenhouses production of green vegetables. The aim of this trial was to evaluate different kinds of trays with coconut fiber substratum to produce net melons with fertirrigation usage under protected environment. The experimet was conducted from March and June of 2006, at the Experimental Station of UNESP, Campus of Ilha Solteira, São Paulo State, Brazil. The treatments consisted of 4 trays (Capillarity gutter, drip gutter, larger sized vase and smaller sized vase) and two net-melon hybrids (Laurent and Maxim). It was adopted the randomize blocks design with four replications. There were 6 plants of each hybrid, in the spacing of 1.2m between rows and 0.5m between plants. The data had been submitted to "Sanest" statistics program and the "Tukey" test, with 5% probability. It was evaluated the electrical conductivity (CE), leave numbers, plants height, average fruit numbers by plants, fruit numbers by area, average mass of fruits, productivity, leaf diagnosis (macro and micronutrients) and solid soluble content rate (SST). Similar or superior values for larger sized fruits production and average mass was shown with larger sized vase, smaller sized vase and drip gutter, however, superior value for productivity presented larger sized vase, meanwhile inferior values was shown with capillarity gutter for the same evaluations. The tow hybrids the Maxim hybrid was pointed as superior through average mass of fruits and larger sized fruits production, while the Laurent, presented greater plants height and solid soluble content, although, of both hybrids are considered as excellent quality.

Resumo: 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. Concluiu-se que a melhor opção de substrato é a combinação de 50% de areia e 50% de casca de amendoim, e como segunda opção a combinação de areia, bagaço de cana-de-açúcar e casca de amendoim em partes iguais...

Abstract: 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...
