摘　　要：异檐花有两种花,生活早期形成众多无融合生殖的雌花,后期产生少量开放两性花。对异檐花植物营养体特征、两种花的形态结构、开放花的传粉和受精、无融合结实现象、果实发育及种子传播进行了观察,并探讨了无融合生殖的生物学意义。Triodanis perfoliata subsp.biflora have two types of flowers:numerous female flowers produced by apogamogony are formed in the early stage of life,and a small number of open bisexual flowers are produced in the later stage.The characteristics of the plant s nutritional body,the morphological structure of the two types of flowers,pollination and fertilization of open flowers,apogamogony,fruit development,and seed dispersal of the subspepcies were observed,and the biological significance of apogamogony is discussed.
