ANÁLISE BIOMÉTRICA DE FRUTOS E SEMENTES DE Passiflora cristalina Vanderplank & Zappi

O objetivo do presente trabalho e caracterizar biometricamente os frutos e sementes de Passiflora cristalina Vanderplank & Zappi ocorrentes na regiao de Alta Floresta, Mato Grosso. Foram coletados em 2013 um total de 100 frutos maduros de 15 genotipos e destes foram selecionadas 300 sementes aleatoriamente. Os frutos foram analisados quanto ao comprimento, largura, espessura, peso, espessura da casca, o peso da polpa, o peso das sementes/fruto, numero de sementes/fruto e teor de solidos soluveis. As sementes foram avaliadas em relacao ao comprimento, largura, espessura e indice de volume. As caracteristicas biometricas foram analisadas mediante distribuicao de frequencia calculando-se o coeficiente de correlacao de Spearman e o nivel de significância atraves do teste T. O comprimento do fruto correlacionou-se positivamente com a largura e peso do fruto, espessura da casca e com peso das sementes, nao havendo uma correlacao com o numero de sementes por fruto. Houve uma ampla distribuicao de frequencia das caracteristicas avaliadas nos frutos, com excecao do peso das sementes. A alta variacao fenotipica encontrada para a maioria das caracteristicas avaliadas nos frutos e sementes de P. cristalina revela que a especie tem divergencia genetica a ser utilizado em programas de selecao e conservacao de recursos geneticos.Palavras-chave: divergencia genetica, maracuja, recursos geneticos. BIOMETRIC ANALYSIS OF FRUITS AND SEEDS OF Passiflora cristalina Vanderplank & Zappi ABSTRACT: The present work has presented the fruits and seeds of Passiflora cristalina Vanderplank & Zappi occurring in the region of Alta Floresta, Mato Grosso. A total of 100 mature fruits of 15 genotypes were collected in 2013 and 300 seeds were randomly selected. The fruits were inert to the length, thickness, thickness, weight, bark thickness, pulp weight, seed/fruit weight, number of seeds / fruit and soluble solids content. The seeds were evaluated for length, width, thickness and volume index. The biometric characteristics were analyzed with the calculation frequency calculated with the Spearman correlation coefficient and the level of significance throughout the T test. Fruit weight was correlated with fruit width and weight, bark thickness and weight of the fruits. Seeds without a key with the number of seeds per fruit. There is an offer of food distribution in the fruits, with the exception of the weight of the seeds. The high phenotypic variance found for a greater number of species evaluated in fruits and seeds of P.cristalina reveals that a type of genetics has been characterized in programs of selection and conservation of genetic resources.Keywords: genetic divergence, passion fruit, genetic resources.
