RESUMO A caracterização e a avaliação de novos genótipos de bananeira é uma etapa importante, tanto para os programas de melhoramento genético quanto para a indicação aos produtores. Assim, o objetivo desta pesquisa foi avaliar a produção e a qualidade de frutos, em pós-colheita, das bananeiras 'Maravilha' e 'Preciosa', no primeiro e segundo ciclo de produção, cultivadas no Submédio do Vale do São Francisco. As mudas, produzidas por cultura de tecidos, foram transplantadas para o campo com seis meses de idade, cultivadas no espaçamento de 3 x 3 m. Nos dois ciclos avaliados, para todas as características, foi adotado o delineamento experimental inteiramente casualizado, com dois tratamentos (cultivares), dez repetições e duas plantas úteis por parcela, com bordadura externa ao ensaio. Foram avaliadas as seguintes variáveis: ciclo de produção (dias entre plantio e colheita), altura de planta, perímetro do pseudocaule, número de folhas adultas, massa da matéria fresca do cacho, número de pencas e de frutos por cacho, massa da matéria fresca da segunda penca; número, comprimento e diâmetro de frutos da segunda penca, relação polpa/casca, firmeza, pH, teor de sólidos solúveis (SS), acidez titulável (AT) e relação SS/AT. O cultivar 'Maravilha' apresentou características de planta e de produção superiores às do 'Preciosa'; quanto às características físico-químicas, o 'Preciosa' apresentou frutos com maiores teores de açúcares, todavia, menores em tamanho; para as demais características, os dois cultivares apresentaram comportamentos semelhantes entre si, no primeiro e no segundo ciclo de produção.

Evaluation of the behavior of banana genotypes in different ecosystems is essential in a breeding program, making it crucial for the production system. The aim of this study was to evaluate the growth behavior of banana 'Prata Anã' (AAB) in the 1 st and 2 nd cycles of production and fruit physical-chemical attributes in the sub-middle region of the São Francisco River Valley. The seedlings were produced by tissue culture in a Biofactory in Cruz das Almas -BA and transplanted to the field after six months, in a spacing of 3 x 3 m. It was evaluated the production cycles (in days) and in each cycle, plant height, pseudostem perimeter and the number of mature leaves. The following characteristicsof production were evaluated: bunch fresh mass, number of cluster and fruits per bunch; fresh mass of the 2 nd cluster, number, length and diameter of fruits in the 2 nd cluster; pulp/skin ratio; firmness, pH, soluble solids (SS), titratable acidity (TA) and SS/TA ratio. There was significant difference for most variables: the second production cycle of banana 'Prata Anã' was shorter than the first, on the second cycle occurred trends of increased growth and better performance of the characters that express production and fruit physical quality. A avaliação do comportamento de genótipos de bananeira em diferentes ecossistemas é essencial ao programa de melhoramento genético, tornando-se de fundamental importância para o sistema produtivo. O objetivo deste trabalho foi avaliar o crescimento da bananeira 'Prata Anã' (AAB), nos 1° e 2° ciclos de produção, e os atributos físico-químicos dos frutos, no Submédio São Francisco. As mudas foram produzidas pelo processo de cultura de tecidos, na Biofábrica de Cruz das Almas, BA, e transplantadas para o campo com seis meses de idade, cultivadas no espaçamento 3 x 3 m. Foram avaliados os ciclos de produção (em dias) e, em cada ciclo, a altura das plantas, o perímetro do pseudocaule e o número de folhas adultas. Quanto à produção, foram avaliadas as seguintes características: massa da matéria fresca do cacho; número de pencas e de frutos por cacho; massa da matéria fresca da 2ª penca; número, comprimento e diâmetro de frutos da 2ª penca; relação polpa/casca; firmeza; pH; sólidos solúveis (SS); acidez titulável (AT) e a relação SS/AT. Verificou-se diferença significativa para a maioria das variáveis analisadas: o segundo ciclo de produção da bananeira 'Prata Anã' foi menor do que o primeiro, sendo que, no segundo ciclo, ocorreram tendências de maior crescimento e de melhor desempenho dos caracteres que expressam a produção e a qualidade física dos frutos.Palavras-chave: Musa sp., desempenho agronômico, características físico-químicas.

Bananas fruits are widely consumed in the world. In Brazil, the role of agriculture activities in the economy and society is huge, especially for banana farmers. The most popular variety of bananas in Brazil are Prata, Grand Naine, Williams and Nanicão; however, all of them have at least one undesirable trait such as height, yield, vegetative cycle, pests and diseases tolerances, drought or cold resistance and fruit quality. This literature review aims to evaluate agronomic performance and fruit quality of new genotypes of the Prata and Cavendish subgroups, and to make further recommendations on high quality genotypes to Brazilian banana producers. Therefore, a literature review of previously acquired data was conducted and the outcomes indicated genotypes’ adaptability to specific region that assessed vegetative and productive attributes of new cultivars, in comparison to most commercially exploited ones, which have already shown high vulnerability to pests and diseases. These outcomes will then facilitate banana producers the opportunity to select the most stable and adaptable genotypes according to environmental conditions.

The objective of this study was to evaluate the effect of cytokinin (BAP) and gibberellin (GA3) applications on the growth, physicochemical characteristics and production of ‘Tommy Atkins’ mango fruits. Mango plants were sprayed with five concentrations (0, 75, 150, 225 and 300 mg.L-1) of BAP and GA3 and BAP + GA3 (0, 75 + 75, 150 + 150, 225 + 225 and 300 + 300 mg.L-1) at 15, 30 and 45 days after anthesis (DAA), single applications of GA3 occurred at 60, 70 and 80 DAA. Fruits were evaluated weekly from 52 DAA for weight, diameter and length until harvest and characterized for soluble solids content and acidity. A higher peak of fruit growth occurred between 66 and 73 DAA. Application of 150 + 150 mg.L-1 (BAP + GA3) promoted at the end of the evaluation period higher fruit weight compared to the other treatments and the control. No significant differences were observed in fruit production, but also concentrations of 150 + 150 mg.L-1 BAP + GA3 led to more than 50% of fruits in the marketing standard type 8. Exogenous application of 150 + 150 mg.L-1 (BAP + GA3) at 15, 30 and 45 DAA increased the weight, diameter, length, acidity and the percentage of fruits type 8 of ‘Tommy Atkins’ mango, but it did not increase yield.

The constant need for innovation in the food industries to meet the demands of consumers and the growing market for gluten-free and high-protein products have driven studies of mixed flour. In this study, 'BRS Platina' banana fruits were processed to obtain Whole Green Banana Flour (WGBF) and Green Banana Pulp Flour (GBPF) as well as leaves of Ora-pro-nóbis Flour (OPNF). Mixed flours were prepared by blending banana flours (WGBF or GBPF) with increasing levels of OPNF (from 5 to 25%). Flours were analyzed for physicochemical characteristics, mineral contents, Water Absorption Index (WAI), Water Solubility Index (WSI), and color. The main component of banana flours was starch, in which GBPF has the highest content. The WGBF had a higher mineral content, and in both flours, the potassium was at a greater level. OPNF showed the highest protein and mineral contents. Independent of the type of banana flour, mixed flours were darker, and had higher WAI and considerable increases in Mg, Fe, and Zn than no mixed ones. The blend of banana flours and Ora-pro-nóbis leaf flour can be a viable combination for preparing a variety of food products, due to its nutritional and technological properties.
