“…is the main product in the international fruit market in the world and the second fruit most produced in Brazil (Reetz, Kist, Santos, Carvalho, & Drum, ). Although Brazil is the fifth largest banana producer country in the world, several factors limit its production, mainly phytosanitary problems caused by nematodes, insects, fungi and bacteria (IBGE, ; Lichtemberg & Lichtemberg, ).…”

Problems caused by nematodes and Fusarium wilt (Panama disease) on banana plantations are responsible for yield losses and are limiting to its cultivation. In the state of Goias, there is little information about the nematode occurence on this crop, and its relation with the incidence of Fusarium oxysporum f.sp. cubense (Foc). This research had the purpose to identify the occurrence of plant‐parasitic nematodes on banana plantations and to verify its correlation with the Fusarium wilt and with the soil attributes (pH, texture, nutrients). Twelve banana orchards in the state of Goias were sampled in the municipalities of Anapolis, Caiaponia, Goiatuba, Itaguaru, Itumbiara (two areas), Jatai, Morrinhos, Ouro Verde, Palestina, Taquaral and Uruana. All sampled areas, except Morrinhos, revealed contamination with Foc, and all areas had different genera of nematodes either in the soil or in the roots samples. Meloidogyne sp., Helicotylenchus sp. and Rotylenchus sp. were the main genera of plant‐parasitic nematodes found in the samples, with Meloidogyne sp. and Rotylenchus sp. being the most dominant and abundant genera. The presence of Pratylenchus sp. increases the population levels of F. oxysporum. Helicotylenchus sp. is highly correlated with high concentrations of Mn. High population density of Meloidogyne sp. was found in irrigated areas with low concentrations of P, Ca, Mg and soil pH.

“…The low postharvest management technology used is one of the restrictive factors for export. In general, the national product does not meet the European and North American market requirements, especially regarding organoleptic and visual aspects LICHTEMBERG, 2011).…”

-The objective of this work was to evaluate the tolerance of fruits of different banana cultivars to low temperature storages. Fruits of the cultivars Nanicão (AAA), Prata (AAB), Vitória (AAAB), Maçã (AAB) and Caipira (AAA) were used. Clusters of three fruits were kept in cold storage for 7, 14 and 21 days, with average temperature of 10.53±0.37°C and relative humidity of 85%. Subsequently, the clusters were transferred to temperatures of 22±0.39°C and evaluated for 16 days. The fruits of all cultivars remained green after 21 days of storage at 10.53±0.37°C. Fruits of the cultivar Nanicão did not completely ripened after transferred to the 22°C storage, when stored for 7 days at low temperature. These fruits were firmer, with green peel and low soluble solids and titratable acidity. The fruits of all cultivars complete the ripening when transferred to room temperature after 21 days of cold storage. Chilling injuries increased with cold storage time in all cultivars. The cultivars Nanicão, Caipira and Maçã had more symptoms of chilling injury, while Prata and Vitória were more tolerant to the cold storage (10.53°C) for up to 21 days, showing normal ripening after transferred to the 22±0.39°C storage.Keywords: Musa spp. Chilling injury.

TOLERÂNCIA AO FRIO DE FRUTOS DE DIFERENTES CULTIVARES DE BANANEIRASRESUMO -O objetivo deste trabalho foi avaliar a tolerância dos frutos de diferentes cultivares de bananeira a baixa temperatura de armazenamento. Foram utilizados frutos das bananas Nanicão (AAA), Prata (AAB), Vitória (AAAB), Maçã (AAB) e Caipira (AAA). Utilizaram-se buquês com três frutos, mantidos em câmara fria por 7, 14 e 21 dias, com temperatura média de 10,53±0,37°C e umidade relativa do ar de 85%. Posteriormente, os buquês foram transferidos para a temperatura de 22±0,39°C e avaliados por 16 dias. Os frutos dos cultivares estudados peraneceram verdes após 21 dias de armazenamento a 10,53±0,37°C. Frutos do Nanicão não completaram o amadurecimento após serem transferidos para a temperatura de 22°C, quando armazenados por 7 dias à baixa temperatura, apresentando frutos mais firmes, com casca verde, baixos teores de sólidos solúveis e acidez titulável. Após 21 dias de armazenamento refrigerado, os frutos de todos os cultivares completaram o amadurecimento, depois de transferidos para temperatura ambiente. Os danos por frio aumentaram com o avanço do tempo de armazenamento refrigerado, para todos os cultivares. Nanicão, Caipira e Maçã apresentaram sintomas mais evidentes de dano por frio. As bananas Prata e Vitória mostraram-se mais tolerantes ao armazenamento refrigerado na temperatura de 10,53°C por até 21 dias, exibindo amadurecimento normal após a transferência para a temperatura de 22°C.Palavras-chave: Musa spp. Injúria por frio.

“…Além dos problemas inerentes à produção e ao elevado consumo interno, o maior fator restritivo à exportação é a baixa tecnologia de manejo pós-colheita dos frutos (Lichtemberg & Lichtemberg, 2011). Assim, estratégias para a melhoria da conservação pós-colheita da banana devem ser obtidas.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de doses de ácido giberélico (GA 3 ) sobre a extensão da vida pós-colheita em banana 'Maçã' e a aplicabilidade de uso de redes neurais artificiais. Utilizou-se o delineamento inteiramente casualizado, em arranjo de parcelas subdivididas, com cinco doses de GA 3 , nas parcelas, e tempos de avaliação, nas subparcelas, e quatro repetições, com um buquê de três frutos por unidade amostral. Os frutos, colhidos com a casca totalmente verde, foram imersos por 10 min, à temperatura ambiente, nos seguintes tratamentos: 0 (controle), 25, 50, 75 e 100 mg L -1 de GA 3 . Os buquês foram armazenados em câmara de refrigeração (20±1ºC, com 91% de umidade relativa do ar). As redes neurais artificiais são eficientes, proporcionando estimativas do coeficiente de determinação maiores às obtidas por modelos de regressão linear múltipla. Após 19 dias de armazenamento, a dose de 100 mg L -1 de GA 3 é mais favorável à conservação pós-colheita de banana 'Maçã', em todas as características avaliadas ao longo do armazenamento.Termos para indexação: Musa, inteligência computacional, qualidade do fruto, regulador de crescimento. Gibberellic acid on postharvest quality of banana 'Maçã' evaluated by artificial neural networksAbstract -The objective of this work was to evaluate the effect of gibberellic acid doses on the extent of banana 'Maçã' postharvest life and the applicability of the use of artificial neural networks. A completely randomized design was carried out in a split-plot arrangement, with five doses of GA 3 in the plots and evaluation times in the subplots, with four replicates, with a three-fruit bunch by sample unit. Fruit were harvested with totally green peel and were immersed for 10 min, at room temperature, in the following treatments: 0 (control), 25, 50, 75, and 100 mg L -1 GA 3 . The bunches were stored in a cold chamber (20±1°C, with 91% air relative humidity). Artificial neural networks are effective, providing estimates of the coefficient of determination higher than those obtained by multiple linear regression models. After 19 days of storage, the dose of 100 mg L -1 GA 3 is more favorable to banana 'Maçã' postharvest conservation, in all the evaluated traits during storage.
