摘要: 研究了泽泻个体发育早期的器官发育顺序。认为可以划分为两个阶段:原胚-成熟种子胚阶段,以苗端发育先于根端和胚芽节生根原基并快于胚根原基为特点;种子萌发-种苗形成阶段,以胚根生长快于胚芽节生根为特点。并指出前者与水生植物芡和睡莲一致,后者与陆生植物条叶龙胆一致。

关键词: 泽泻, 个体发育, 器官发育顺序

Abstract: The Organic development sequence of Alisma orientale in early stage of ontogeny was studied. Two stages were divided:proembryo-mature seed embryo stage is characterized by the development of shoot apex being earlier than root apex, and plumular nodal root primodium, and being faster than radicle primodium; seed germination-seeding formation stage is characterized by the radicle growth being faster than plumular nodal root. And it was pointed out that the aquatic plants Euryale ferox and0 Nymphaea caerulea are of same characters as the former and the land plant Gentiana manshurica is of same characters as the latter.

Key words: Alisma orientale, Ontogeny, Organic development sequence
