摘要: 通过调整叶果比、环剥和应用CPPU 等处理, 研究了源库关系的变化对‘秦美’猕猴桃果实特
性的影响。结果表明, 源库关系的变化对果实大小的影响大于对品质和其他特性的影响; 结果蔓上叶果比2~ 4!1 可以满足果实正常生长发育的需要; 果实库力是影响果实大小的主要因素。对果实细胞数目与果实大小、硬度与Ca 含量之间的关系进行了讨论。

关键词: 猕猴桃, 环剥, 叶果比, CPPU

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
