| 摘 要： | 盛花期对银杏雌株叶面喷施多效唑，B9，GA3，GA3＋6－BA。结果表明，多效唑和B9能够明显提高坐果率，有效增加来年成花数量，GA3和GA3＋6－BA对提高坐果无影响，但能增加种子重量，促进纵，横径增加，GA3还能够促进翌年成花数量，多效唑处理提高产量的原因，一是抑制树体营养生长，二是减少落花落果，增加植株翌年成花量。

| Abstract: | The female ginkgo trees were treated with paclobutrazol,B 9,GA 3,GA 3 6 BA respectively during flowering period. The results show that paclobutrazol and B 9 improved seed set and increased the flowers in next year.GA 3 and GA 3 6 BA increased seed weight, across and vertical diameter of seed but didn't improve seed set.Increased seed yield obtained from the paclobutrazol may result from reduced vegetative growth of trees and decreased flower and seed drops. |
