| 摘 要： | 该文是广西蕨类植物孢子形态研究的第一部分。首次利用光学显微镜和扫描电子显微镜对广西产水龙骨科6属9种植物的孢子形态进行了观察研究。对每个种的孢子形态特征及表面纹饰进行了描述。水龙骨科6属9种植物孢子都为单裂缝类型孢子，孢子外壁表面具有皱状、细孔状、蠕虫状、瘤状、光滑、索状条纹和颗粒状纹饰7种纹饰类型。讨论了各属、种问的差异，为水龙骨科系统分类及孢粉学研究提供资料。

| Abstract: | This paper is the first report of an investigation on the spore morphology of Guangxi ferns. The spore morphology of 9 species, belonging to 6 genera of Polypodiaceae distributing in Guangxi of China was studied and compared under LM and SEM. The spore morphological characters of each species were described. The main results were as fol lows ; the spore morphology of 9 species were all monolete. Under SEM, the exine of spores showed rugate, punctate, vermiculate, tuberculate, psilate, funicle and granum ornamentations. The differences among the spores of these genera and species were discussed. It seems to contribute to the materials for systematics and palynology of Polypodiaceae. |
