摘  要:
雌雄同株榕树的花序果内雌花子房分层明显,特别是在雄花期。大叶榕花序内子房主要分3层,雌花期时雌花主要集中在中层。雄花期时,种子主要集中在外层,虫瘿主要分布在中层。花梗和子房长度的差异是造成大叶榕雄花期子房分层的主要因素,子房分层使榕果内的不同小蜂和种子形成了空间上的生态位,表明子房的分层是调节种子和小蜂产出的主要因素。

摘  要:
In monoecious figs,ovaries of female florets are obviously stratificated,especially in the male phase.According to the length of pedicel and ovary,the galls of Ficus virens var.sublanceolata could be classified into three layers.The florets were mainly in the intermediate layer in female-phase.In the male-phase,the seeds were mainly in the outer layer,while the galls were mainly in the inner layer.The spatial layout in figs engendered different ecological niche of seeds and fig wasps,which also played a great role in the reproductive ecology of Ficus and the output of fig wasps.
