Description
Summary:ABSTRACT Several criteria have been used to determine fruit maturity, which are based on the appearance and chemical composition of the produce at harvest time. The objective of this study was to evaluate the physical, chemical and physiological changes that occur during the development of mango cv. ‘Ubá’, aiming to determine the stages of fruit development until complete maturation. The experiment was carried out in an approximately 30-year-old orchard in Visconde do Rio Branco, MG (21º00'37"S, 42º50'26"W and 352 m altitude). Weekly, 25 fruits of 15 hoses were collected from the anthesis to the complete maturation in the plant. Samplings took place from August 2007 to January 2008. The characteristics evaluated were length, smaller and larger diameter; CO2 production; color parameters L*, a*, and b* of skin and pulp; fresh and dry mass (fruit, skin, pulp, and seed); solute leakage; pulp firmness; soluble solids (SS); titratable acidity (TA); SS/TA ratio; Vitamin C; carotenoids, starch, and soluble sugars. The development of mango fruit cv. ‘Ubá’ took 23 weeks. The developmental pattern fit a simple sigmoidal model. Fruits attached to the plant reached the respiratory climacteric stage between 20 and 21 weeks after anthesis. RESUMO Vários critérios têm sido utilizados na determinação da maturidade de frutos, baseados na aparência e na composição química do produto na época da colheita. Objetivou-se avaliar as mudanças físicas, químicas e fisiológicas ocorridas durante o desenvolvimento da manga ‘Ubá’, visando estabelecer as fases de desenvolvimento do fruto para o completo amadurecimento. O experimento foi desenvolvido em pomar com cerca de 30 anos de idade em Visconde do Rio Branco, MG (21º00’37”S, 42º50’26”O e altitude de 352 m). Semanalmente, desde a antese até o completo amadurecimento na planta, foram coletados 25 frutos de 15 mangueiras. As amostragens ocorreram de agosto de 2007 a janeiro de 2008. As características avaliadas foram: comprimento, menor e maior diâmetro; produção de CO2; parâmetros de cor L*, a* e b* da casca e da polpa; massa fresca e seca (fruto, casca, polpa e semente); extravasamento de solutos; consistência da polpa; sólidos solúveis (SS); acidez titulável (AT); ratio (razão SS/AT); vitamina C; carotenoides, amido e açúcares solúveis. O desenvolvimento da manga ‘Ubá’ estendeu-se por 23 semanas. O padrão de desenvolvimento ajustou-se a um modelo sigmoidal simples. O climatérico respiratório dos frutos ligados à planta foi atingido
