| 摘要: |
| 本文对我国16属,27种菊苣族植物的果实进行了解剖学研究,主要结果为:(1)属间果壁结构差异很大,属内种间果壁结构比较一致;(2)据果壁结构,将16属归为四亚族,即菊苣亚族、还羊参亚族、毛莲菜亚族和鸦葱亚族,(3)叉枝鸦葱可能是鸦葱亚族向还羊参亚族进化的中间类型;(4)果实横切面形状、果棱形状、数目或缺如,果壁结构等特征可作为该族植物分类上的依据。 |

| Abstract: |
| The present paper studies the anatomy of fruit in 16 genera and 27 species belonging to the tribe Cichorieae.The main results are as follows.(1) The structure of fruit wall is significantly different in various genera of lliis tribe- The structure of fruit wall is rather uniform in various species of genera; (2) According lo the fruit wall structure, If genera can be classified into 4 subtribcs. i ,e. Cichorinae, Crepidinae, Picrinae and Scorzonerinae;(3)Scorzonera muriculata is likely lo be the medial type cvoluting from Scorzonerinac to Crepidinae;( 4 )The shape of fruit transverse section,the shape and (he quantity of jugum, the structure of mcsocarp can he served as the most imporianl characters for Cichoricae taxonomy. |
