Harvesting at suitable maturation stages is determinant in maintaining post-harvest quality of umbu fruit. In this sense, the aim of this work was to determine the influence of the maturation stage on the physical-chemical quality of umbu fruits from the brazilian northeast. The experiment was conducted at the Food Technology Laboratory of the Agrarian Sciences Center of the Federal University of Roraima, Boa Vista, Roraima, Brazil. The experimental design was a completely randomized design with ten replicates and one fruit per experimental unit. The treatments consisted of three maturation stages of the fruits: green, once and ripe. The physical characteristics evaluated were: fruit length, fruit diameter, seed mass, bark mass, pulp mass, total mass and pulp yield. The determination of the chemical quality was evaluated: pH, soluble solids content, titratable acidity and soluble solids ...

Objetivou-se com esse trabalho avaliar as características agronômicas de doze cultivares de melancia produzidas nas condições edafoclimáticas do cerrado de Roraima. O experimento foi desenvolvido no Campo Experimental Água Boa da Embrapa Roraima. O delineamento experimental foi em blocos ao acaso com quatro repetições e seis plantas por parcela. Os tratamentos consistiram das cultivares: Combat, Conquista, Verena, Congo, Magnum, Electra, Santa Amélia, Explore, Emperor, Crimson Select Plus, Charleston Gray Super e Omaru Yamato. Avaliaram-se as características produtivas, de sementes e de qualidade dos frutos. Concluiu-se que as condições edafoclimáticas do cerrado de Roraima favorecem as características produtivas e qualitativas dos frutos das cultivares de melancia analisadas. A maior produtividade foi encontrada no cultivar Crimson Select Plus, com média de 67848,25 kg ha...
