| 摘 要： | 通过多年、多点的试验，研究了ＣＰＰＵ对猕猴桃果实生长发育的影响和ＣＰＰＵ促进猕猴桃果实增大的最适使用时期。结果表明：从花后５ｄ到６０ｄ，所有处理都明显地增大了果实，增长的幅度随处理时间的推迟而减弱。猕猴桃果实的增长基本上呈Ｓ曲线：在花后３周内，果实增长缓慢；此后的一个月内，果实增长加快；再往后，增长的速度下降，保持相对同等的速度继续增长，直至采收。与对照比较，处理果实的快速增长更加明显，ＣＰＰＵ对促进猕猴桃果实增大的作用能持续很长的时期。最有效的使用时期是在花后１０—３０ｄ，正值果实的快速生长时期。

| Abstract: | Studies on the influence of CPPU on the fruit growth and the timing of it’s application were carried outfrom 1992 through 1993. The fruit growth expressed as a typical S curve, Initially the fruIt grew extremelyslowly within 3 weeks after bloom, and then grew very fast over a period abOut 3 5weeks.Further,thegrowth rate sharply decreased keeping a steady increase in growth rate till harvest.The fruit size promotingeffect of CPPU was evident in the whole period of fruit growth.The most effective period for CPPU applica-tion was in the duration 10 30 davs after bloom. |
