北京蹄盖蕨属孢子形态的研究

STUDLES ON THE SPORE MORPHOLOGY OF ATHYRLUM ROTH.IN BEIJING

本文利用扫描电子显微镜辅以光学显微镜的方法，详细观察并描述了北京蹄盖蕨科蹄盖蕨属５种即东北蹄盖蕨（Ａｔｈｙｒｉｕｍｂｒｅｖｉｆｒｏｎｓ），河北蹄盖蕨（Ａ．ｈｅｂｅｉｅｎｓｅ），中华蹄盖蕨（Ａ．ｓｉｎｅｎｓｅ），多齿蹄盖蕨（Ａ．ｍｕｌｔｉｄｅｎｔａｔｕｍ），华北蹄盖蕨（Ａ．ｐａｃｈｙｐｈｌｅｂｉｕｍ）孢子的形态结构，讨论了各种间的差异，为蹄盖蕨科系统分类提供孢粉学方面的依据。

The spores of 5 species of Athyrium Roth.observed under LM and SEM,the morphological characteristic of species are described in detail.The spore morphology of 5 species is different form each other,especially,in the characters of ornamentation it can be taken as a evidence of classification among them.
