摘要: 利用光学显微镜详细观察蹄盖蕨科(Athyriaceae)2属4种植物,即蹄盖蕨属的尖头蹄盖蕨(Athyrium vidalii)、长柄蹄盖蕨(A.longius)和喜马拉雅蹄盖蕨(A.fimbriatum)以及亮毛蕨属的亮毛蕨(Acystopteris japonica)配子体发育过程,记录配子体各发育阶段的特征。4种植物的孢子都为单裂缝,两侧对称,孢子萌发类型为向心型,配子体发育类型为铁线蕨型,性器官都为薄囊蕨型,成熟原叶体为对称的心脏形,无毛状体;种间差异包括孢子纹饰、孢子萌发时间、配子体形成时间、丝状体长度、片状体和原叶体的形态以及性器官大小。

Abstract: Light microscopy was used to observe the spore germination and gametophytic development of four species i.e. Athyrium vidalii, A.longius, A.fimbriatum and Acystopteris japonica belonging to two genera in Athyriaceae. The characteristics of each gametophytic developmental stage were recorded. Spores of four species are monolete, bilaterally symmetrical, the germination is Centripetal-type and the gametophyte development is Adiantum-type, sex organs are of the type of leptosporangiate, adult gametophytes are cordate, no hairs; differences among species include spore ornamentation, germination time, formation time of the prothallus, filament length, plate shape, prothallus shape and sex organ size.

Key words: Athyriaceae, gametophyte, development, Athyrium vidalii, A.longius, A.fimbriatum, Acystopteris japonica
