| 摘 要： | 测定了银杏朱和雄株实生树内源激素及核酸含量在生长季节的变化。结果表明，在３月上旬芽膨大时芽尖中赤霉素含量已达高峰，随后急剧下降，到９月中下旬降到最低点。６月上旬芽尖中玉米素含量升到最高值，生长素则降到最低点，而脱落酸减少到检测水平以下。

| Abstract: | The
content of endogenous hormones and nucleic acids in the bud tip of Ginkgo biloba,both
female plant and male plant,was measured.The results showed that content of GA3 in
bud tip ofthe female was higher than the male by 26%,at the time of differentiation of
floral buds,followed then by a decrease in content which was still higher in the female
than in the male.When floral buds differentiating,the female was higher than the male
by 71% in content of ZT,while the male had a content of IAA higher than the female by
25%.In the light of nucleic acids content,the female was more than the male at the time
of differentiation of floral buds.This analysis indicated that the female differed apparently
from the male in content of endogenous hormones and nucleic acids.In addition,the
relationship between plant sex and variations in endogenous homones and nucleic acids
