摘要: 在光学显微镜下观察了水鳖蕨(Sinephropteris delavayi(Franch. ) Mickel)配子体发育的详细过程。水鳖蕨孢子培养6 d左右萌发;原丝体单列细胞,或发育出2~3个分支;片状体生长点不明显,成熟配子体近心形。本文还讨论了其生长点、毛状体及性器的发育特点,结果支持Mickel将水鳖蕨独立成属的观点。

关键词: 水鳖蕨, 配子体

Abstract: Gametophytic development of Sinephropteris delavayi(Franch.) Mickel in Brittonia was first studied by the microscope. The spores germinate at about 6 days after cultured. The germ filiaments developments are uniseriate and can forked into 2~3 branches. The meristem of prothallial is unconspicuous. Mature prothallu are approximately cordate. We also discussed the characteristic of meristem, hair and sexual organs so that can show the reasonable view of Mickel who divided into an unique genus S.delavayi.

Key words: Inephropteris delavayi(Franch.) Mickel, gametophyte
