“…Of the many questions about organic foods, the most important are those related to productivity and sensorial quality characteristics, with references to the reduced size of fruits and increased sugar contents, when fruits are obtained in an organic way (BORguINI;tORReS, 2006). Ribeiro et al (2012) verified that the chemical attributes of bananas are little affected by the cultivation system and that organic management allows greater chemical distinction of cultivars.…”

-the northern semiarid region of Minas gerais is an important producer of irrigated Prata-Anã banana variety, which is highly susceptible to fusarium wilt. the organic cultivation of resistant varieties may be an phytosanitary alternative, also adding value to fruits. this study aimed to characterize banana varieties produced in organic system based on chemical and physical assessments at post-harvest. Prata-Anã, BRS Platina, Fhia-18, BRS Conquista and BRS tropical varieties were characterized at the point of harvest (green) and mature (stage six of maturation), by chemical and physical assessments. At the point of harvest, BRS Conquista and BRS tropical banana varieties had more intense green skin color. 'BRS Conquista' presented lower fresh weight, shorter length and diameter than the other varieties. BRS Platinum variety had more fruit fresh mass, length and diameter. Mature Prata-Anã, BRS Platina, Fhia-18, BRS Conquista and BRS tropical banana varieties showed no difference in soluble solids, ph, titrable acidity and ratio; BRS Platina variety had more intense yellow skin color and lower pulp/skin ratio. greater dropping resistance occurred in BRS Conquista variety and BRS tropical was less resistant. Prata-Anã banana variety showed higher firmness. Banana varieties differed more by the physical characteristics (skin color, size, dropping resistance, firmness and pulp/skin ratio) in relation to chemical characteristics. Index Terms: Musa spp., varieties, postharvest. QUALIDADE DE BANANA ORGÂNICA PRODUZIDA NO SEMIÁRIDO DE MINAS GERAISRESUMO -A região norte de Minas gerais, semiárida, é importante produtora de banana 'Prata-Anã' irrigada, cultura altamente suscetível ao mal-do-panamá. O cultivo orgânico de variedades resistentes pode ser uma alternativa fitossanitária, além de agregar valor aos frutos. Objetivou-se caracterizar, em pós-colheita, variedades de banana produzidas em sistema orgânico, com base em avaliações químicas e físicas. As variedades Prata-Anã, BRS Platina, Fhia-18, BRS Conquista e BRS tropical foram caracterizadas no ponto de colheita (verdes) e maduras (estádio seis de maturação), por avaliações químicas e físicas. No ponto de colheita, bananas 'BRS Conquista' e 'BRS tropical' tiveram a cor da casca verde mais intensa. A 'BRS Conquista' apresentou menor massa fresca, menor comprimento e diâmetro do fruto em relação às demais variedades. A 'BRS Platina' produziu frutos com maior massa fresca, comprimento e diâmetro. Bananas 'Prata-Anã', 'BRS Platina', 'Fhia-18', 'BRS Conquista', e 'BRS tropical', maduras, não apresentaram diferença no teor de sólidos solúveis, pH, acidez titulável e ratio; a 'BRS Platina' obteve a casca com tonalidade amarela mais intensa e menor relação polpa/casca. Maior resistência ao despencamento ocorreu em 'BRS Conquista', e a 'BRS Tropical' foi menos resistente. A banana 'Prata-Anã' apresentou maior firmeza. As variedades diferiram mais pelas características físicas (cor da casca, tamanho, resistência ao despencamento, firmeza e relação polpa/casca) em rela...

-In the present work were evaluated the effects of propolis coatings of various botanical sources on quality traits of bananas cv. Prata (Musa sapientum L.) stored at room temperature. ´Prata´ bananas were selected and submitted to five postharvest treatments: four coatings applied by immersion in propolis extracts at a concentration of 2.5% (w/v) and a control (without coating). Propolis extracts were applied as 1) a wild type aqueous propolis extract, 2) a wild type hydroalcoholic propolis extract, 3) a rosemary green type hydroalcoholic propolis extract and 4) a red type hydroalcoholic propolis extract. The bananas were evaluated at three-day intervals along 12 days for fresh weight losses, flesh firmness, soluble solids (SS), titratable acidity (TA), the ratio SS/TA and pH. Sensory analyses were performed after three and six days of storage by 55 not trained panelists designed for acceptability. At the end of the twelve-day storage period, bananas coated either with the rosemary green hydroalcoholic extract or with the aqueous extract presented lower fresh weight losses in comparison to the bananas of the control treatment. No differences were determined in relation to flesh firmness and along the storage period TA values decreased and pH values increased in bananas of all treatments. SS contents increased towards the end of the storage period that, consequently, contributed to increases in the SS/TA ratio. The most significant increase in SS/TA ratio was determined in bananas coated with the red type hydroalcoholic extract. Taste panelists did not detect significant differences amongst coated and not coated cv. Prata bananas up to six days of storage. Index terms: Musa sp., hydroalcoholic extract, taste panel, fruit acceptability, storage. EXTRATO DE PRÓPOLIS NA CONSERVAÇÃO PÓS-COLHEITA DE BANANA 'PRATA'RESUMO -Este trabalho foi realizado com o objetivo de avaliar os efeitos do revestimento com extrato de própolis de diferentes fontes botânicas sobre as características físico-químicas de banana 'Prata' (Musa sapientum L.), armazenada à temperatura ambiente. Bananas 'Prata' foram selecionadas e submetidas à cinco tratamentos pós-colheita, sendo quatro formas de revestimento por imersão em extrato de própolis de diferentes fontes botânicas com concentração de 2,5% (m/v) ("extrato aquoso de própolis do tipo silvestre", "extrato hidroalcoólico de própolis do tipo silvestre", "extrato hidroalcoólico de própolis do tipo verde alecrim e "extrato hidroalcoólico de própolis do tipo vermelho ") e um controle (sem revestimento). As variáveis avaliadas foram perda de massa, firmeza da polpa, sólidos solúveis (SS), acidez titulável (AT), relação entre sólidos solúveis e acidez titulável (SS/AT) e potencial hidrogeniônico (pH), realizadas em intervalos de 3 dias por 12 dias de armazenamento. Realizou-se a análise sensorial das bananas aos 3 e 6 dias de armazenamento, avaliadas por 55 provadores não treinados através do teste de aceitação. Ao final de 12 dias de armazenamento, os revestimentos de extrato de própo...

“…This reduction in the content of SS in fruits from plants under organic fertilization was not expected since many studies, especially those related to plants under organic management, point to a rise in the levels of SS in fruit from plants under organic management (Damatto Junior et al, 2005, Sarmento et al, 2012, not only for passion fruit, but for other tropical fruits like bananas, where organic management was found to allow a higher mean value compared to conventional cultivation system for Silver-dwarf cultivar (Ribeiro et al, 2012). In addition, yellow passion fruits that received nitrogen fertilizer as urea (Venâncio et al, 2013), showed lower SS content than the fruits receiving OF and OMF in this study.…”

-Growing yellow passion fruit is a profitable activity, with a high demand for labor, and it is practiced especially by family-based farmers. However, the production cost is rather high and a significant part of this cost is associated with the expenses related to fertilization and phytosanitary treatments necessary for obtaining satisfactory yields and high commercial quality fruit. Therefore, the objective of this study was to evaluate the effect of using organic compound in fertilization of plants and alternative products in phytosanitary treatments (Bordeaux mixture, Neem oil and lime sulfur mixture) on the yield and quality of fruits. Yellow passion fruits were submitted to three types of fertilization (mineral, organic and organic-mineral) and two types of phytosanitary treatment ('conventional' and 'alternative'). This experiment evaluated fruit yield (kg/plant) and fruit quality by using the following evaluations: seedless pulp yield, soluble solids content (SS), titratable acidity (TA), SS/TA ratio and vitamin C content. The different types of fertilization did not interfere in fruit yield, however, plants under conventional phytosanitary treatment displayed higher yields. The SS content and TA of the fruits were influenced only by fertilization, where plants that received mineral and organic-mineral fertilization produced fruit with higher contents of SS and TA. Pulp yield, SS/TA ratio and vitamin C content were not influenced by any of the evaluated factors. Regarding cultivation of passion fruit, it is possible to substitute some mineral fertilizers for organic fertilizers with no negative effects on the fruit yield or quality. However, the substitution of pesticides for alternative products compromises fruit yield.Keywords: alternative products, mineral fertilization, organic-mineral fertilization, Passiflora edulis Sims f. flavicarpa Deg.
