摘要:

从花发育研究的方法、花发育与被子植物花部结构的多样性、花发育与被子植物的系统发育以及
花发育的分子遗传学等四个方面对近年来被子植物系统学中花发育研究的主要进展作一综述,例举了
 一些重要结果。同时,对该领域今后研究的方向和应注意的一些问题作了简要评论。作者认为植物的
形态结构可以看作是一个时空过程,在系统学研究中对花部性状的分析和认识应该树立动态的观点。
今后应该从动态的角度开展被子植物花的发生和发育以及性状在不同类群间的比较等方面的广泛研
究,并加强对在被子植物花的起源和演化中起重要作用的花部同源异型现象的发育过程的观察。

Abstract:

 With the advent of new methods and techniques, floral development has been ex-
 tensively studied in many groups of angiosperms recently. These studies have resulted in
notable progress and greatly increased our knowledge about the diversity of floral structure and
 developmental patterns as well as phylogenetic relationship of angiosperms. This field is be-
 coming an active and exciting one in systematics of flowering plants. The present paper re-
 viewed this progress from four aspects: (1) the methods of studies on floral development;
 (2) floral development and the diversity of floral structure; (3) floral development and phy-
 logeny of angiosperms; (4) molecular genetics of floral development. In addition, several fu-
 ture directions and some problems needing attention in this field are discussed: (1) extensive
 studies on floral developmental studies of extensive species of angiosperms and comparison of
 floral structures among them; (2) research of floral development of homeotic flowers as well
 as their systematic and evolutionary value; (3) floral structure should be studied from the
 viewpoint of dynamics, because the structure of plants can be seen as a spatio-temporal pro-
 cess, and the use of structural categories in systematics may distort the natural dynamics.
