| 摘要: |
| 对我国产川滇蹄盖蕨(Athyrium mackinnonii)配子体发育进行了观察.结果表明:川滇蹄盖蕨的孢子为两面体型,两侧对称,极面观为椭圆形,赤道面观为豆形,周壁具皱状纹饰;孢子萌发为向心型;原叶体发育为铁线蕨型,成熟原叶体为对称的心脏形,雄配子体为带状.该研究试图为蹄盖蕨科植物的系统分类研究积累资料. |

| Abstract: |
| The gametophyte development of Athyrium mackinnonii from China was observed under artificial culture in this paper.The results show that the spore of Athyrium mackinnonii is bilaterally symmetric,elliptic in polar view,fabaceous in equatorial view,the rugate is formed by the perispore.The pattern of spore germination is of Centripetal-type.The prothallial development is of Adiantum-type.The developed prothallial is cordiform.The male gametophyte is strip-shaped.It provides some information for system classification of Athyriaceae. |
