摘要
通过对菱属4个种类的载培观察,研究菱属的传粉生物学.结果表明:(1)不同种类的及同一种类但产地不同的菱属植物,其开花时间存在差异;2)气候条件对菱属的开花时间有较大影响;(3)菱属的传粉模式是以自花授粉为主,异花授粉起辅助作用,同时也可能存在着一定程度的无融合生殖.
AbstractFour species of Trapa were cultivated for the study of the pollination biology in the same experimental area. The results show,1. There is difference in the flowering time from different species or the same species with from different localities.2. The flowering time of Trapa is affected by weather.3. The pollination type of Trapa is that the self-pollination occupies a dominant position and the cross-pollination is supplementary; besides, there is a certain degree apomixis.
