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。
Light microscopy was used to observe the spore germination and gametophytic development of four species i.e. Athyrium vidalii, A. longius, A. fimbriatum and Acystopte~ 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.
