摘要: 利用扫描电子显微镜对我国产蹄盖蕨属44 种植物的孢子进行了观察。结果表明, 该属孢子形态为单裂缝, 两侧对称, 极面观为椭圆形, 赤道面观为豆形。外壁表面光滑, 由周壁形成表面纹饰。根据周壁的结构和表面纹饰, 可分为两种类型:一是周壁外层发达, 形成粗大的脊状纹饰, 有11 种属此类型;二是周壁外层很薄或不完全发育, 由周壁内层或中层形成表面纹饰, 有33种属此类型纹饰。本文还就本属的孢子形态特征以及与本属的属下分类关系、本属与邻近属的关系等进行了讨论。

Abstract: Spore morphology of 44 species of the genus Athyrium from China was examined by SEM. The spore morphology of the genus is monolete, bilaterosymmetric, polar view ellipsoidal, equatorial view phaseoliform, exospore plain. The surface ornamentation of the spore was formed by perispore. Based on surface ornamentation and other features, the spores of the genus Athyrium are divided into two types. In type I, the outer layer of perispore is complete, surface ornamentation of spore is formed by outer layer of perispore, which is usually rugate folds on the spore surface. 11 species among them have this pattern. In type II, the outer layer of perispore is thin or incomplete, the surface ornamentation of spore is formed by inner layer or middle of perispore. 33 species among them have this pattern. The relationship of the spore morphology and taxonomy in Athyrium was discussed in this paper.
