| 摘 要： | 在人工条件下对我国产单叶双盖蕨（Diplazium subsinuatum (Wall. ex Hook. et Grev.) Tagawa）配子体发育进行了观察。结果表明：单叶双盖蕨的孢子为两面体型，两侧对称，极面观为椭圆形，赤道面观为圆肾形，周壁具粗刺状或棒状突起；孢子萌发为书带蕨型；原叶体发育为铁线蕨型，成熟原叶体为心脏形。该研究试图为蕨类植物的系统分类积累资料。

| Abstract: | The gametophyte development of Diplazium subsinuatum(Wall. ex Hook. et Grev.) Tagawa from China was observed under artificial culture in this paper. The results show that the spore of Diplazium subsinuatum is bilaterally symmetric, elliptic in polar view, circinal-reniform in equatorial view, the echinate or baculate is formed by the perispore. The pattern of the spore germination is of Vittaria-type. The prothallial development is of Adiantum-type. The developed prothallial is cordiform. This study provides some information for system classification of pteridophytes. |
