Dynamic Changes of Fruit Physiological Quality and Sugar Components during Fruit Growth and Development of Actinidia eriantha

‘Ganlv 1’ is a new cultivar of Actinidia eriantha selected from the wild natural population, which has advantages moderate taste, high yield, easy peeling and ascorbic acid (AsA) content. In this study, was used to explore changes in fruit quality, soluble sugar components, sucrose metabolism-related enzymes activities enzyme genes’ expression during fruit’s development. The results showed that, except for AsA, quality index growth development basically exhibited same trend. shape different stages fruit, tended be stable with dynamic dry matter content indicated that best time harvest about 160 days after full bloom. main components were fructose, glucose sucrose, sugars soft-ripening stage. trend accumulation, genes 130–145 bloom (DAFB) might critical period metabolism. are great significance clarifying developmental characteristics A. fruits, lay foundation further studying mechanism metabolism eriantha.
