RESUMO -As cultivares de bananeira mais plantadas no Brasil são suscetíveis às principais doenças da cultura, estando em curso a busca por variedades resistentes que possam substituí-las com boa aceitação dos produtores e consumidores. O objetivo deste trabalho foi avaliar as características físicas, químicas e sensoriais de frutos da bananeira 'Prata-Anã' e seu híbrido 'BRS Platina', armazenados a 15 °C e a 25 °C, ao longo do amadurecimento. O delineamento experimental foi o inteiramente casualizado, no esquema fatorial 2 (genótipos) x 2 (temperaturas) x 4 (estádios de maturação). Os frutos foram avaliados sensorialmente e quanto à coloração da casca, diâmetro, comprimento, resistência ao despencamento, firmeza, massa com e sem casca, espessura da casca, relação polpa/casca, sólidos solúveis, pH, acidez titulável, açúcares totais, açúcares redutores e amido. A 'BRS Platina' apresenta frutos com maior diâmetro, comprimento e massa, acidez semelhante e menor doçura em comparação à 'Prata-Anã'. O armazenamento a 15 ºC confere maior firmeza e resistência ao despencamento aos frutos de 'Prata-Anã' e 'BRS Platina', em comparação com o armazenamento a 25 ºC. Os frutos de 'BRS Platina' apresentam índice de aceitação satisfatório, porém inferior ao obtido para os de 'Prata-Anã'. Termos para indexação: Musa spp., conservação, despencamento, genótipos tipo Prata, PA42-44. POST HARVEST TRAITS OF BANANAS 'PRATA-ANÃ' AND 'BRS PLATINA'UNDRE COLD STORAGEABSTRACT -Banana cultivars grown in Brazil are susceptible to major banana diseases, it has been underway to search for resistant varieties that can replace them with good acceptance by producers and consumers. This study aimed to evaluate the physical and chemical characteristics of banana fruits of 'Prata Anã' cultivar and its hybrids 'BRS Platina', stored at 15 °C and 25 °C. The experimental design was entirely at random in factorial scheme 2 (genotypes) x 2 (temperature) x 4 (ripening stage). The fruits were evaluated as for sensory analysis, and skin color, diameter, length, finger drop resistance, firmness, weight with and without skin, skin thickness, pulp/peel ratio, soluble solids, pH, acidity, total sugars and starch. The 'BRS Platina' genotype shows better characteristics with fruit size, it is similar as for acidity and lesser sweetness compared to 'Prata Anã' cultivar. Storage at 15 °C increases firmness and resistance to dropping of 'Prata Anã' and 'BRS Platina' fruits in comparation to storage at 25 °C. The 'BRS Platina' fruits had satisfactory level of acceptance, however lower than 'Prata Anã'.
-Repeatability analysis has been used to study traits in several crops, assisting in the definition of the minimum number needed to evaluate genotypes more efficiently and with less time and resource consumption. So far, however, no repeatability studies on cactus pear have been found in the literature. The objective of this study was to determine the coefficient of repeatability for cactus pear fruits traits and the minimum number of evaluations (fruit) that can provide acceptable accuracy for the prediction of the true value. The experiment was conducted at the Federal Institute of Bahia/Campus Guanambi, with 150 fruits collected from three municipalities in the state of Bahia. The coefficients of repeatability were estimated by the methods of analysis of variance, principal components based on the covariance (PCCV) and correlation (PCC) matrices, and structural analysis based on the correlation matrix (SA). The analysis of variance showed that, except for fruit diameter, the effect of the production site (municipality) was significant for all traits evaluated. The PCCV method was proven the most suitable for studying the repeatability of quality traits of cactus pear fruits. Seven fruits were required to determine, with 90% confidence, the traits length, diameter, fruit firmness, skin thickness, number of seeds, fruit mass, bark mass, pulp mass, pH, titratable acidity, soluble solids, SS/AT ratio, and pulp yield.
