Abstract

To explore the fruit development characteristics of Actinidia chinensis ‘Hort16A’, fruit shape indexes during 2-154 d after anthesis, contents of soluble sugar and titratable acid in fruit during 30-154 d after anthesis, and contents of organic acid components in fruit during 44-147 d after anthesis were analyzed. The results show that fruit of ‘Hort16A’ grows rapidly during 30-44 and 58-72 d after anthesis. Content of soluble solid in fruit during 100-140 d after anthesis is slightly higher than that during 2-93 d after anthesis, and increases rapidly during 147-154 d after anthesis. Fruit firmness decreases rapidly during 147-154 d after anthesis. In general, during 30-154 d after anthesis, content of soluble sugar in fruit increases gradually, while content of titratable acid decreases firstly, then increases, and decreases again. In the fruit, tartaric acid is not detected, content of quininic acid is the highest, contents of malic acid and citric acid are higher, and contents of succinic acid and fumaric acid are very low. Total content of organic acids increases firstly and then decreases, and reaches the highest value at 140 d after anthesis. It is suggested that in order to improve fruit quality of ‘Hort16A’, its cultivation and management plans will be set up based on fruit development characteristics.
