4种蕨类植物孢子形态的扫描电镜观察

OBSERVATIONS ON 4 SPORES MORPHOLOGY OFTHE PTERIDOPHYTA BY SEM.

本文利用扫描电镜对中国产水蕨（Ｃｅｒａｔｏｐｔｅｒｉｓｔｈａｌｉｃｔｒｏｄｅｓ），粗梗水蕨（Ｃｅｒａｔｏｐｔｅｒｉｓｐｔｅｒｉｄｏｉｄｅｓ），光叶藤蕨（Ｓｔｅｎｏｃｈｌａｅｎａｐａｌｕｓｔｒｉｓ），亚洲光叶藤蕨（Ｓｔｅｎｏｃｈｌａｅｎａａｓｉａｔｉｃａ）的孢子做了扫描电镜的观察．对每个种的孢子形态特征进行描述，为蕨类孢子形态学的研究提供资料．

In this paper, the spores of Stenochlaena asiatica Ching et Chiu, Stenochlaena palustris (Burm) Bedd, Ceratopteris thalictroides (L.) Brongn and Ceratopteris pteridoides (Hook.) Hieron from China were studied by SEM. The morphological characteristics of each species were described and summarized. It may supply materials for the spore morphology.
