摘　　要：对黑藻（Hydrilla verticillata）个体发育中的胚胎发育（从合子到种子胚）和种苗发育（从种子到种苗）进行了研究。发现沉水植物黑藻与挺水植物泽泻（Alisma orientale）在胚柄只有1—2个细胞、种子胚苗端发达根端未分化、萌发后根端始分化、分生区之上产生根环与下胚轴毛、初生根短命等特点上基本相同，并对这些特点进行了讨论。The embryogeny from zygote to seed embryo and the seedling development from seed to seedling of Hydrilla verticillata were studied in this paper. They were discovered that the 1 - 2 celled suspensor, the developed shoot end and undifferentiated root end of embryo, the root end differentiated after seed germinating, the root collar and hypocotylar hair arised from the top of the meristematic zone of the primary root in seedling of Hydrilla verticiliata are same as Alisma orientale, and these characters were discussed finally.
