Abstract: The adjustment of leaf/ fruit ratio, girdling and the application of CPPU were taken to investigate the influence of sink or source change on fruit characteristics in Qinmei ( Actinidia deliciosa) . The results showed that the fruit size fluctuated more remarkably than fruit quality and other characteristics after different treatments. The leaf/ fruit ratio 2- 41 in fruiting lateral could meet the normal demand of fruit growth and development. The
competitive ability of fruit not source strength is a major factor determining the final fruit size. The relationship be btween cell number and fruit size as well as that between hardness and Ca content was discussed.

Key words: Kiwifruit, Girdling, Leaf/ fruit ratio, CPPU
