摘要
一般学者均认为银杏是雌雄异株植物，虽然也有些文献记载“稀为同株”，但缺乏有力的证据。５０年代有人曾对被认为是雌雄同株的银杏进行过调查和报道，但对是否自然形成的真正雌雄同株难于定论。１９９５年，作者在山东滕州市采集花粉时发现，在１株２０ａ生银杏的大枝上，雌雄花同步。经过２ａ的调查研究。
Ginkgo is generally considered as dioecious although hermaphrodite trees were ever recorded which,but,could not be confirmed with facts.In the 1950s,hermaphrodite ginkgo trees were investigated and reported,but no conclusion ahout whether or not there were true natural hermaphrodite was created.However,we found a branch on a 20 year old ginkgo tree possessing both male and female flowers.Two years of investigation confirmed this ginkgo tree is hermaphrodite.
