摘要
报道在光学显微镜下,观察到的东方荚果蕨配子体发育的过程。培养5d左右孢子萌发;丝状体单列细胞;片状体发育方式为槲蕨型(Drynaria type);成熟雄配子体近心形,成熟雌配子体呈阔圆心形;毛状体由1—3个细胞组成;精子器发育方式为水龙骨科型(Polypodiaeeae type);配子体中部及基部细胞内存在哑铃型叶绿体;在近原丝体细胞中,可观察到极不规则的叶绿体;假根单细胞,丝状。
Gametophytic development of Matteuccia orientalis ( Hook. ) Trey. was studied by the micro- scope. The spores germinate about 5 days after cultured. The germ filaments develop are uniseriate. The prothallial development is of Drynaria type. Mature male prochallu are approximately cordate and mature female prochallu are broad-round cordate. Hairs consist of 1 - 3 cells. Antheridia development is of the Polypodiaceae type. Dumbbell-like chloroplasts locate in middle and basal cells of prochallu. Extraordina- rily irregular chloroplasts are observed near germ filament of prochallu. Rhizoids develop are unicellular and filiform. Content of this paper provides basal data for systemic biology and cytobiology.
