Application methods of biostimulants affect the production and postharvest conservation of yellow melon

Worldwide, Brazil holds the fifth position in melon fruits exportation, further expanding its products to provide for the growing demand. This expansion is the result of the development and application of new technologies, including the management of the use of biostimulants. However, for melon crops, the information in the literature on the use of biostimulants remains limited to the effects of different doses on fruit quality at the time of harvest. Therefore, this study aimed to evaluate the influence of different methods of pre-harvest application of two biostimulants on the production and postharvest conservation of fruits of yellow melon cv. Iracema. The treatments consisted of a combination of three factors: two plant biostimulants (Crop Set® and Spray Dunger®), two application methods of the products (fertigation and spraying), and five times of postharvest storage (0, 14, 21, 28 and 35 days). An additional control treatment corresponded to plants without biostimulant application. The fruits were evaluated for production and physicochemical attributes: average mass, yield, flesh firmness, titratable acidity, soluble solids content, SSC/TA ratio, pH, total soluble sugars, and weight loss. Fertigation is the recommended application method of biostimulants for yellow melon due to its effect on the increase of average mass, yield, flesh firmness, soluble solids content, and total soluble sugars of the fruits in relation to the spraying method.

Real Power Loss Reduction by Melon Fly Optimization and Spontaneous Process Algorithm's

Abstract In this work Melon Fly Optimization (MFO) Algorithm and Spontaneous Process Algorithm (SPA) is designed to reduce the Real power loss, voltage stability enhancement and reducing the Voltage deviation. In this work real power loss measured and how much loss has been reduced is also identified by suitable comparison with standard algorithms. In this society from common consumer to industry needs better quality of power continuously and constantly without much variation. One way to improve the quality of the power is to reduce the power loss. Also reduction of power loss will improve the economic conditions of the nation indirectly and it improves the productivity of the nation with any hurdles. Around the world all nations sequentially identifying the method to reduce the power loss in the transmission and subsequently it improve the quality of power. MFO algorithm has been formed based on the innate events of Melon fly. Due their very excellent eyesight and mutual supportive behaviour Melon fly will find the food without difficulty. By smell and vision the Melon fly will move to the best location form the current location. In the preliminary level Melon flies will search the food in multiple directions and they may be far away from the food source, it like scattering in the plane. Then Spontaneous Process Algorithm (SPA) is designed to solve the optimal reactive power problem Formulation of the projected algorithm is done by imitating the process done during nuclear fission and fusion. Every item of a nucleus attribute symbolizes each solution variable. Sequence of operators directs the nucleus and in order to avoid the local optimum it will imitate the dissimilar condition of reaction. In the exploration space nucleus symbolizes the variables and potential solution. Levy flight has been intermingled in the procedure to enhance the diversification and intensification in the search. Evaluation of validity of the Melon Fly Optimization (MFO) Algorithm and Spontaneous Process Algorithm (SPA) is done in IEEE 30-bus system by considering voltage stability (L-index) and also devoid of L-index criterion. Minimization of voltage deviation, voltage stability enhancement and power loss minimization has been achieved.

Melon cultivation irrigated with saline waters promote chemical alterations in an acrisol / Cultivo de melão irrigado com águas salinas promove alterações químicas em argissolo

The objective of the present study was to evaluate the salinization process and the changes in the chemical properties of an Acrisol cultivated with melon irrigated with water of different saline concentrations. The experiment was carried out in the field conditions using the experimental design of randomized blocks, arranged in split-plot. The plots were composed of salinity levels of irrigation water, expressed in terms of water electrical conductivity (ECw): 0.54; 1.48; 2.02 dS m-1; and the sub-plots for melon cultivars: Sancho and Medellín (Toad Skin), Mandacaru (Yellow), Nectar (Galia) and Sedna (Cantaloupe). Soil samples were collected at the beginning and end of the crop cycle to evaluate the changes in the physical-chemical properties of the soil. The electrical conductivity of saturation extract in the soil profile varied for each cultivar, observing high salinity values in soils with cultivars with lower water demand (Sedna and Nectar). The salinity of the soil was lower than the electrical conductivity of the irrigation water in the treatments with high values of ECw. The soil pH values showed little reaction in relation to the initial values. The exchangeable sodium percentage values were approximate twice the sodium adsorption ratio of the saturation stratum.(AU)

O objetivo do presente estudo foi avaliar o processo de salinização e as alterações dos atributos químicos de um Argissolo cultivado com melão irrigado com água de diferentes concentrações salinas. O experimento foi desenvolvido em campo aberto utilizando o delineamento de blocos casualizados em parcelas subdividas. As parcelas constituíram de níveis de salinidade da água de irrigação, expressa em condutividade elétrica da água (CEa): 0,54; 1,48; 2,02; 3,03 e 3,90 dS m-1 e, as sub-parcelas de cultivares de melão: Sancho e Medellín (Pele de Sapo), Mandacaru (Amarelo), Néctar (Gália) e Sedna (Cantaloupe). Amostras de solos foram coletadas no início e no final do ciclo da cultura para avaliação do processo de salinização e das alterações dos atributos físico-químicos do solo. Os resultados mostraram que a ECse no perfil do solo variou para cada cultivar, sendo as maiores salinidades observadas nos solos cultivados com as cultivares que utilizam uma menor demanda hídrica (Sedna e Néctar). A salinidade do solo foi sempre inferior ao da condutividade elétrica da água de irrigação nos tratamentos com maiores CEa. Os valores de pH do solo apresentaram pequena reação em relação aos valores iniciais. Os valores de porcentagem de sódio trocável foram cerca de duas vezes superiores ao da razão de adsorção de sódio do estrato de saturação. (AU)

Efficiency of nitrogen and potassium application on phytotechnical parameters and yield of melon / Eficiência da aplicação de nitrogênio e potássio sobre caracteres fitotécnicos e rendimento do meloeiro

Phytotechnical parameters, yield and fertilizer use efficiency are relevant to the rational management of fertigation, especially in cultivation of high technological level. Thus, the objective was to evaluate the influence and efficiency of nitrogen (N) and potassium (K) application on the phytotechnical parameters, yield and nutritional efficiency of yellow melon in a fertigation system. The experiment was conducted in the city of Bom Jesus-PI, Brazil, from January to April 2016, in a strip-block design with four replicates, and the treatments consisted of five N levels (0, 45, 90, 135 and 180 kg ha-1 in the form of urea) and five K levels (0, 60, 120, 180 and 240 kg ha-1 in the form of potassium chloride), applied through fertigation. Collar diameter, main branch length, leaf chlorophyll content, number of leaves, leaf area index, biomass accumulation, fruit yield, and N and K use efficiencies were evaluated. Applications of 180 kg ha-1 of N and 240 kg ha-1 of K, respectively, led to the highest growth of the melon, while maximum production was obtained with the use of 112.50 and 165 kg ha-1 of N and K, respectively. The efficiency of N and K use decreased with increasing levels.

As características fitotécnicas, de rendimento e de eficiência de uso dos fertilizantes são relevantes para o manejo racional da fertirrigação, especialmente em cultivo de elevado nível tecnológico. Níveis crescentes de N e K promoverão maior crescimento e produtividade do meloeiro. Neste sentido, objetivou-se avaliar a influência e a eficiência da aplicação de nitrogênio e potássio sobre as características fitotécnicas, de rendimento e de eficiência do meloeiro amarelo em sistema de fertirrigação. O experimento foi conduzido na cidade de Bom Jesus ­ PI, Brasil durante o período de janeiro a abril de 2016. O delineamento experimental adotado foi de blocos em faixas com quatro repetições, e os tratamentos constituídos por cinco níveis de nitrogênio (0, 45, 90, 135 e 180 kg ha-1 na forma de ureia) e cinco níveis de potássio (0, 60, 120, 180 e 240 kg ha-1na forma de cloreto de potássio) aplicados via fertirrigação. Avaliou-se os caracteres fitotécnicos, rendimento de frutos e as eficiências de uso do nitrogênio e do potássio. As aplicações de 180 kg ha-1 de N e 240 kg ha-1 de K promoveram maior crescimento do meloeiro, enquanto que a máxima produção foi obtida com o uso de 112,50 e 165 kg ha-1 de nitrogênio e potássio, respectivamente. As eficiências de uso do nitrogênio e do potássio diminuíram com o aumento dos níveis aplicadas.

Physiology and yield of piel de sapo melon (Cucumis melo L. ) under water deficit in semi-arid region, Brazil / Fisiologia e rendimento do meloeiro pele-de-sapo (Cucumis melo L. ) cultivado sob diferentes regimes hídricos em região semi-árida, Brasil

Melon (Cucumis melo L.) is a crop of great socioeconomic importance in regions with semiarid climate, as found in Northeast Brazil. In this region water deficit is a usual condition as well as the main reduction factor of plant productivity. Due to this phenomenon, irrigation techniques are used to make available the amount of water needed for plant production. Therefore, this study evaluated the physiology and fruit production changes of 'Juazeiro' Piel de sapo melon plants under different water replacement rates. 'Juazeiro' melon was grown under four reference evapotranspiration replacement rates (40, 60, 80 and 100% of ETo) distributed randomly in blocks with 5 replicates. The plants were cultivated in the field, in an experimental area located in the Brazilian Northeast region, under hot and dry semiarid climatic conditions, and during the growing cycle the 'Juazeiro' hybrid melon plants were evaluated for leaf area, biomass accumulation, gas exchange, photochemical efficiency of photosystem PSII and production of fruits per plant. Application of water replacement rates of 100% ETo leads to highest growth, net photosynthesis, and fruit yield of 'Juazeiro' melon. Water replacement at 80% ETo can be used for 'Juazeiro" melon under semiarid climatic conditions, but with small losses in fruit yield. Water replacement below 80% ETo leads to drastic reductions in growth, gas exchanges, quantum efficiency of photosystem II and fruit yield, which impairs melon production in semi-arid climate environments. KEYWORDS: Fruits yield. Gas exchange. Photochemical efficiency. INTRODUCTION Melon (Cucumis melo L.) is an important socioeconomic fruit cultivated in the world. Melon fruit production was 29.6 million tons and this production is distributed among China, Turkey, Iran, Egypt, India, United States, and Brazil. These countries account for 70% of the world production (FAO, 2017). In Brazil, cultivated area exceeded 22.000 ha with more than 521.6 thousand tons in 2015. 94.7% of this production was obtained in the semi-arid region of Northeast, mainly in the states of Ceará and Rio Grande do Norte, the largest producers in the country (IBGE, 2014). However, especially due to irregular rainfall, melon fruit production has been dropping in the last few years in this region. According to Pereira Filho et al. (2015), melon plants growth, development, and fruit production are greatly affected by climate conditions, mainly by water stress. Water stress is one of the most complex physiological phenomena because it is a multidimensional component which can considerably limit agricultural crops growth and development (DOGAN et al., 2008; LISAR et al., 2012; SILVA et al., 2015), generally in arid and semi-arid regions, such as in Northeast Brazil. Moreover, plant adaptability to water deficit conditions is related to a range of events occurring at several levels (LISAR et al., 2012), observed as a physiological, biochemical, and molecular adaptations, among others. At plant physiological level, soil water deficit has a significant effect on gas exchange, because it is a result of the limitation of stomatal conductance, and it is considered the primary cause of photosynthetic inhibition due to CO2 influx limitation, as well as water efflux from transpiration Received: 08/04/19 Accepted: 20/12/19

O meloeiro (Cucumis melo L.) é uma cultura de grande importância social e econômica mundial, principalmente em regiões de clima semiárido como o Nordeste brasileiro, onde déficit hídrico é condição comum e considerado o principal fator de redução da produtividade das plantas. Tal fenômeno força a utilização da irrigação como forma de disponibilizar a quantidade de água necessária à produção. Assim, objetivou-se com este trabalho avaliar as variações fisiológicas e produtivas de meloeiro pele-de-sapo submetidos a diferentes taxas de reposição hídrica. O híbrido 'Juazeiro' de melão pele-de-sapo foi cultivado sob quatro taxas de reposição da evapotranspiração de referência (40, 60, 80 e 100% da ETo), distribuídas em blocos ao acaso com 5 repetições. As plantas foram cultivadas em campo, em área experimental situada no Nordeste brasileiro, em condições clima semiárido quente e seco, e durante o ciclo de cultivo as plantas de meloeiro híbrido 'Juazeiro' foram avaliadas quanto a área foliar, o acúmulo de biomassa, as trocas gasosas, eficiência fotoquímica do fotossitesma PSII e produção de frutos por planta. A aplicação de taxas de reposição hídrica a 100% da ETo proporciona o maior crescimento, fotossíntese liquida e produção do meloeiro 'Juazeiro'. A reposição hídrica a 80% da ETo pode ser usada para o cultivo do meloeiro 'Juazeiro' em condições de clima semiárido, admitindo-se pequenas perdas no rendimento. A reposição hídrica com lâminas inferiores a 80% da ETo promove reduções drásticas no crescimento, trocas gasosas, eficiência quântica do fotossistema II e produção, que inviabilizam a produção do meloeiro em ambientes de clima semiáridos.

Association between fruit and vegetable allergies and pollen-food allergy syndrome in Japanese children: a multicenter cross-sectional case series

BACKGROUND: Recently, the prevalence of food allergies during childhood is increasing, with fruits being common allergens. However, data on allergens that cause fruit and vegetable allergies and pollen-food allergy syndrome (PFAS) in childhood are relatively few. This study aimed to examine the allergens in fruit and vegetable allergies in pediatric patients and to determine the association between fruit and vegetable allergies and PFAS.OBJECTIVE: This study aimed to examine the current status of fruit and vegetable allergies in Japanese children.METHODS: This was a multicenter case series observational study. The participants included children aged <15 years who developed allergic symptoms after eating fruits and vegetables and subsequently received treatment in the Pediatric Department of 6 hospitals in the Osaka Prefecture in Japan during the study period from August 2016 to July 2017. Participants' information was obtained using a questionnaire, and data were obtained by performing several types of allergy tests using blood samples.RESULTS: A total of 97 children (median age, 9 years; 56 males) were included in the study. Apple was the most common allergen, followed by peach, kiwi, cantaloupe, and watermelon. A total of 74 participants (76%) exhibited allergic symptoms due to PFAS; moreover, pathogenesis-related protein-10 (PR-10) was the most common allergen superfamily. On the contrary, in the group where neither PR-10 nor profilin was sensitized, kiwi and banana were the most common allergens, and the age of onset was lower than that in the PFAS group. Specific antibody titer was significantly associated with Birch for Bet v1 and latex for Bet v2 (r = 0.99 and r = 0.89).CONCLUSION: When we examine patients with fruit and vegetable allergies, we should first consider PFAS even in childhood specifically for children greater than 4 years old.

Influência da torrefação no rendimento de óleo de sementes de melão obtido por extração assistida por ultrassom / Influence of roasting on the yield of melon seeds obtained by ultrasound-assisted extraction

Os resíduos do processamento de frutas, como o melão, têm se tornado um problema para as agroindústrias, pois são gerados em grandes quantidades e podem provocar danos ao meio ambiente quando descartados inadequadamente. Diante disto, o objetivo deste trabalho foi estudar a influência da torrefação no rendimento de óleo das sementes de melão obtido por extração assistida por ultrassom. Para tanto, as sementes foram caracterizadas físico-quimicamente, e o rendimento de óleo foi estudado em relação à temperatura e o tempo de torrefação, utilizando um fatorial 22 com blocos casualizados. Os resultados mostraram que a temperatura e o tempo de torrefação influenciaram no rendimento do óleo de sementes de melão, sendo que os maiores rendimentos de óleo foram obtidos nas condições de 89 ºC por 53 minutos e de 131 ºC por 17 minutos.

Does the high density of trichomes influence the parasitism of Liriomyza sativae by Opius scabriventris on melon cultivars? / A alta densidade de tricomas influencia no parasitismo de Liriomyza sativae por Opius scabriventris em cultivares de meloeiro?

Opius scabriventris (Hymenoptera: Braconidae) is considered an important parasitoid of the leafminer Liriomyza sativae (Diptera: Agromyzidae) in the main melon (Cucumis melo L.) producing areas in Brazil. However, there is no information on the influence of trichomes on melon plant leaves on the parasitoids' actions. Therefore, the aim of this investigation was to relate the influence of columnar trichome density on melon cultivars in the parasitism of L. sativae larvae by O. scabriventris. The study was conducted in laboratory conditions, in which melon cultivars were infested and the leafminer larvae were subjected to the parasitism. The results demonstrated that trichome density can influence the parasitism of L. sativae larvae by O. scabriventris. Among the studied materials, Piel de Sapo cultivar showed the highest density of trichomes in the leaves (534 trichomes/cm2) and the lowest parasitism (20%).(AU)

Opius scabriventris (Hymenoptera: Braconidae) é considerado um importante parasitoide da mosca-minadora Liriomyza sativae (Diptera: Agromyzidae) nas principais áreas de produção de melão (Cucumis melo L.) do Brasil, no entanto, não há informações se a densidade de tricomas das folhas do meloeiro pode influenciar a ação desses parasitoides. Portanto, o objetivo deste trabalho foi relatar a influência da densidade de tricomas colunares de cultivares de meloeiro no parasitismo de L. sativae por O. scabriventris. O trabalho foi realizado em condições de laboratório, em que os cultivares foram infestados e as larvas da mosca-minadora submetidas ao parasitismo. Os resultados demonstraram que a densidade dos tricomas pode influenciar no parasitismo de larvas de L. sativae por O. scabriventris. Entre os materiais estudados, o cultivar pele-de-sapo apresentou a maior densidade de tricomas nas folhas (534 tricomas/cm2) e o menor parasitismo (20%).(AU)

Screening of melon genotypes for resistance to vegetable leafminer and your phenotypic correlations with colorimetry

ABSTRACT Melon is one of the most important vegetable crops in the world. With short cycle in a system of phased planting, phytosanitary control is compromised, and a great volume of agricultural chemicals is used to control vegetable leafminer. Genetic control is an ideal alternative to avoid the damage caused by this insect. Thus, the aim of this study was to evaluate Cucumis accessions in regard to resistance to leafminer and correlate the variables analyzed. Fifty-four accessions and four commercial hybrids of melon were tested. The study was divided into two experiments: with and with no choice. The following characteristics were evaluated: with choice, in field - subjective score based on the infestation and the number of mines per leaf; and with no choice, in cage - number of mines per leaf, chlorophyll content, and leaf colorimetry. The results showed variability among the accessions and some genotypes showed favorable results for resistance in both experiments. There was correlation between the two variables in the experiment in the field. The accessions CNPH 11-282, CNPH 06-1047, and CNPH 11-1077 are the most recommended for future breeding programs with aim on introgression of resistance to vegetable leafminer in melon.

Antipyretic effects of hydro-methanol extract ofMelia azedarach Linn, seeds and Cucumis melo Linn, seeds in experimental rabbits

To investigate the antipyretic activity of hydro-methanol extract of Melia azedarach Linn. [HMEMA] seeds and Cucumis melo Linn. [HMECM] seeds in experimental animals. Baker's yeast was used to induce fever in rabbits which were divided into six groups. The animal groups were thereafter administered distilled water [control], paracetamol [reference standard, 150mg/kg], HMEMA [250mg/kg], HMEMA [500mg/kg], HMECM [250mg/kg] and HMECM [500mg/kg] respectively. HMEMA and HMECM were also phytochemically screened for tannins, alkaloids, phenols, flavonoids, saponins and cardiac glycosides. Results indicate that hydro-methanol extract of M. azedarach Linn. Seeds [250mg/kg and 500mg/kg] significantly [p<0.001, p<0.05 respectively] reduced the elevated body temperature in dose dependant manner. Insignificant to no antipyretic effect was produced by hydro-methanol extract of Cucumis melo L. seeds. Phytochemical analysis of the HMEMA showed the presence of flavonoids, saponins, tannins, phenols, alkaloids and cardiac glycosides While HMECM was positive for flavonoids, phenols and saponins. The result shows that there exists a potential benefit in utilizing Melia azedarach L. seeds in treating fever. This property can be attributed to the presence of phytochemical constituents present in the hydro-methanol extract ofMelia azedarach L. seeds and the exact mechanism need to be evaluated

Avaliação hemogasométrica, bioquímica e hematológica de ovinos suplementados com melão / Effects of sudden intake of melon on blood gas, biochemical and hematological parameters of sheep

O presente trabalho avaliou os efeitos da administração de duas diferentes quantidades de melão sobre variáveis hemogasométricas, bioquímicas e hematológicas de ovinos não adaptados. Foram utilizados 12 ovinos canulados, pesando 25kg de peso vivo, que nunca receberam ração concentrada. Os animais receberam dieta à base de feno (2,3% do peso vivo) e água à vontade. Os ovinos foram distribuídos aleatoriamente em dois grupos e receberam 25% ou 75% da matéria seca (MS) da dieta de melão triturado (G25% e G75%, respectivamente) diretamente no rúmen. Foram realizadas coletas de sangue e determinação do pH ruminal nos seguintes tempos: zero, 3, 6, 12, 18 e 24 horas após oferecimento do melão. Foi realizada análise hemogasométrica, do volume globular, determinação da concentração plasmática de lactato-L, glicose e osmolaridade sérica. No G25%, o pH sanguíneo variou entre 7,40 e 7,31, enquanto o G75% apresentou pH entre 7,38 e 7,26. Maiores concentrações de glicose plasmática foram detectadas no G75% no T3, T6 e T12 (P<0,05). Os ovinos que receberam 25% de melão mantiveram parâmetros sanguíneos dentro da normalidade, ao passo que, no G75%, os ovinos apresentaram discreta acidose metabólica sistêmica e hiperglicemia. A suplementação com 25% de melão pode ser uma alternativa segura na alimentação de ovinos.

This study evaluated the effects of two different amounts of melon on blood gas, biochemical and hematological variables of sheep not adapted. We used 12 cannulated sheep weighing 25 kg which never received concentrate. The animals received hay-based diet (2.3% of body weight) and water ad libitum. The sheep were randomly divided into two groups and received 25% or 75% of the dry matter (DM) of the diet of crushed melon (G25% and G75%, respectively) directly into the rumen. Blood collection and determination of ruminal pH were made at the following times: zero, three, six, 12, 18 and 24 hours after administration of the fruit. In whole blood was performed blood gas analysis and packed cell volume; in the plasma it was determined the concentrations of L-Lactate and glucose and in the serum the osmolarity. At G25% the blood pH ranged between 7.40 and 7.31, while G75% showed pH between 7.38 and 7.26. Higher concentrations of plasma glucose were detected in G75% after 3, 6 and 12 hours (P <0.05). Sheep receiving 25% of melon showed blood parameters within the normal range, while in the G75%, sheep had a mild systemic metabolic acidosis and hyperglycemia.

Antecedentes: El encogimiento y los cambios morfométricos de las frutas durante el secado son fenómenosdifíciles de evaluar puesto que los alimentos no son tejidos homogéneos y sus propiedades físicasse ven afectadas por su contenido de humedad. Objetivos: El objetivo de este artículo fue describir loscambios morfométricos en la superficie de esferas de melón durante el secado por fluidización, empleandoel análisis de imágenes y la teoría fractal. Métodos: Las imágenes de esferas de melón fueron obtenidascon una videocámara durante el secado por fluidización. Las variables de estudio fueron: velocidad, enniveles de 2, 3 y 4m/s, y temperatura del aire de secado a 70° y 80°C. El encogimiento de las esferas demelón fue definido como A/Ao, donde Ao y A fueron las dimensiones original y final de las esferas duranteel secado, respectivamente. Seis zonas de medición fueron seleccionadas en la superficie de las esferaspara evaluar el contenido de humedad (CHZ). Los cambios morfométricos de la superficie de las esferasdeshidratadas fueron evaluados mediante la dimensión fractal de la textura (DFSDBC) de las imágenesobtenidas durante el secado por fluidización. Resultados: Se observó un decremento irregular del encogimiento(A/Ao) de las esferas vs. Tiempo de secado. Las condiciones de secado que registraron mayorirregularidad en la contracción de la esfera fueron 70°C y 2 m/s, condiciones en las cuales se produjerondistribuciones del contenido de humedad (CHZ) en la superficie de la esfera.

Shrinkage and morphometric changes of fruit during drying are phenomena difficult to evaluate since foodstuff are not homogeneous material and their physical properties are strongly influenced by its moisture content.Objectives:The aim of this paper was to describe, by means of image analysis and fractal theory the morphometric changes in the surface of melon spheres during spout fluidizedbed drying. Methods: Images of melon spheres during spout fluidized bed drying were obtained with a videocamcorder. The studied variables were the dry airflow, at levels of 2, 3, and 4 m/s; and dry air temperature at 70 and 80ºC. The shrinkage was defined as ratio of areas (A/Ao) of melon spheres, where Ao and A were initial and final dimensions of the spheres during drying, respectively. Six measurement zones were selected on the surface of the spheres to evaluate moisture content (MCZ). Surface morphometricchanges of dehydrated spheres were evaluated by means of fractal dimension of the texture (FDSDBC) of the obtained images during fluidized bed drying.Results: It was observed an irregular decreasing of spheres shrinkage (A/Ao) vs. drying time. The highest irregularity in the contraction of the sphere was obtained at drying conditions of 70ºC, and 2 m/s. At these conditions, a distribution of moisture content zones (MCZ) in the surface of melon spheres were observed. Distribution of MCZ generated the onset of zones with different moisture contents, along the drying on the surface of the spheres, which produced a non-homogeneous dehydration of the melon spheres. FDSDBC values were between 2.22 and2.30. It was observed that morphology changes of surface were progressive because of the dehydration.Conclusions: Morphometric changes on surface of melon spheres were influenced by a distribution of MCZ on the surface, found during spout fluidized bed drying. FD SDBC values of the surface of melon spheres were increased, indicating a rougher surface during.

Potencialidades fitoquímicas do melão (Cucumis melo L. ) na região Noroeste do Rio Grande do Sul - Brasil / Phytochemical potentialities of melon (Cucumis melo L. ) in the northwest region of Rio Grande do Sul - Brazil

O melão (Cucumis melo L.) é uma fruta muito apreciada por suas qualidades e sua produção vem crescendo e ganhando espaço no mercado nacional e internacional. Em regiões como o Noroeste do Rio Grande do Sul, destaca-se como uma nova alternativa de renda para vários agricultores. Neste contexto, o presente trabalho teve como objetivo analisar o potencial fitoquímico de alguns cultivares de melão da região Noroeste do Rio Grande do Sul. A análise fitoquímica utilizando como farmacógeno as folhas, foi realizada para a verificação da presença de metabólitos secundários, tais como: saponinas, cumarinas, cardiotônicos, cianogenéticos, alcalóides, taninos, antraquinonas, flavonoides, e óleos voláteis. Também foi avaliado o teor de suco a partir dos frutos. Dentre os cinco cultivares analisados, Gaúcho, Imperial, Hy Mark, Magelan, e Cantaloupe, o cultivar Gaucho apresentou a maior variedade em metabólitos secundários. Na avaliação do teor de suco a cultivar Magelan se destacou em comparação às demais cultivares testadas.

The melon (Cucumis melo L.) is a fruit highly appreciated for its qualities and its production has been growing and gaining space in the national and in the international market. In regions like the northwest of Rio Grande do Sul - Brazil, it stands out as a new income alternative for farmers. In this context, this study aimed to analyze the phytochemical potential of some melon cultivars in the northwest region of Rio Grande do Sul. The phytochemical analysis, using the leaves as pharmacogen, was performed to verify the presence of secondary metabolites such as saponins, coumarins, cardiac glycosides, cyanogenetic glicosides, alkaloids, tannins, anthraquinones, flavonoids and volatile oils. The juice content from the fruits was also evaluated. Among the five analyzed cultivars, Gaucho, Imperial, Hy Mark, Magelan and Cantaloupe, cultivar Gaucho had the greatest variety of secondary metabolites. In the assessment of the juice content, cultivar Magelan was superior compared to the remaining tested cultivars.

Transformation of Didymella bryoniae mediated by Agrobacterium tumefaciens / 生物工程学报

Gummy stem blight, a plant disease caused by Didymella bryoniae, is one of the major diseases in melon. The disease can seriously reduce melon yield and quality. However, little information is available on the genetics and functional genomics of the fungal pathogen. In this study, we developed an Agrobacterium-mediated transformation system for D. bryoniae by using a universal pathogenic isolate DB11 and the Agrobacterium tumefaciens strain C58C1 carrying plasmid pBIG2RHPH2 harboring the hygromycin B phosphotransferase gene (hph). Total 45 transformants could be obtained per 1 x 10(5) spores when 1 x 10(6) spores per milliliter of D. bryoniae spore suspension were cocultivated with Agrobacterium cells at OD600 = 0.15 for 48 h in the presence of induction medium (pH 5.2) containing acetosyringone at 200 microg/mL and selection medium contained 100 microg/mL of hygromycin B and 200 microg/mL of cefotaxime sodium, ampicillin and tetracycline, respectively. The transformants were stable when grown on PDA medium without hygromycin B for five times and were verified by PCR amplification with the hph primers and by Southern blot analysis with the hph probe. The transformation system will be useful for further studies of functional genes in D. bryoniae.

Detecção de Listeria spp. e Salmonella spp. em superfícies de melão (Cucumis melo), melancia (Citrullus vulgaris) e mamão (Carica papaya), pelo método imunoenzimático TECRA VIA e procedimentos de cultura / Detection of Listeria spp. and Salmonella spp. in melon (Cucumis melo), watermelon (Citrullus vulgaris) and papaya (Carica papaya), by immunoenzyme TECRA VIA method and procedures for culture

Neste trabalho, foram avaliadas a incidência de Salmonella spp. e Listeria spp. em superfície de frutas, melões (Cucumis melo), melancias (Citrullus vulgaris) e mamões (Carica papaya), coletadas em feira livre e na central de abastecimento (CEASA) em Campinas-São Paulo, Brasil. De um total de 120 frutas 42 amostras foram analisadas simultaneamente pelo método imunoenzimático TECRA-VIA e BAM modificado para presença de Salmonella e por um método canadense Health Protection Branch e TECRA-VIA para detecção de Listeria. As 78 amostras restantes foram analisadas somente pelos métodos de cultura. Salmonella spp. não foi encontrada em nenhuma das 42 amostras analisadas por ambas metodologias sendo que o método TECRA VIA apresentou um falso positivo. Contudo Listeria spp. foi detectada em 1 (2.38 por cento ) das amostras analisadas e apresentou 2 resultados falsos positivos quando utilizado o método TECRA – VIA. Salmonella spp. também não foi constatada nas 78 amostras analisadas apenas pelo método BAM modificado. Contudo, Listeria spp. foi detectada em 9 (7.50 por cento) das amostras analisadas, sendo que L. innocua e L. grayii foram isoladas e L. welshimeri de melão quando utilizado o método canadense Health Protection Branch. As amostras coletadas em feira livre mostraram uma freqüência maior de Listeria quando comparadas com as obtidas no CEASA.

Qualidade microbiológica do melão minimamente processado, armazenado sob atmosfera modificada / Microbiological quality of minimally processed melon stored under modified atmosphere

Este trabalho teve como objetivo avaliar o efeito da atmosfera modificada na qualidade microbiológica do melão minimamente processado. O experimento foi conduzido com melão Orange Flesh, produzidos no Rio Grande do Norte e obtidos no GEA-GESP-SP. Os cubos de melões foram sanitificados com 100 mg L de hipoclorito de sódio por 1 minuto, lavados, drenados e embalados com diferentes concentrações de O2 e CO2 em sacos plásticos de polietileno (Nylon Poli), com características de alta barreira ao oxigênio e ao vapor d´água. Os produtos foram avaliados a cada dois dias durante dez dias quanto a sua qualidade microbiológica. A modificação da atmosfera inibiu o crescimento de bactérias psicrotróficas, fungos filamntosos e leveduras e inibiu o desenvolvimento de coliformes a 35ºC e 45ºC.

Occurrence of Fruit Rot of Melon Caused by Sclerotium rolfsii in Korea

In 2007 to 2008, a fruit rot of Melon (Cucumis melo L.) caused by Sclerotium rolfsii occurred sporadically in a farmer's vinyl house in Jinju City. The symptoms started with watersoaking lesion and progressed into the rotting of the surface of fruit. White mycelial mats appeared on the lesion at the surface of the fruit and a number of sclerotia formed on the fruit near the soil line. The sclerotia were globoid in shape, 1~3 mm in size, and white to brown in color. The hyphal width was measured 3 to 8 microm. The optimum temperature for mycelial growth and sclerotia formation was 30 on PDA. Typical clamp connections were observed in hyphae of grown for 4 days on PDA. On the basis of symptoms, mycological characteristics and pathogenicity to the host plant, this fungus was identified as Sclerotium rolfsii Saccardo. This is the first report of the fruit rot of Melon caused by S. rolfsii in Korea.
