| 摘 要： | 用1/2MS培养基培养假鞭叶铁线蕨(Adiantum mdesianum Chatak)孢子,光学显微镜下观察孢子萌发及配子体发育过程.结果表明:成熟的孢子棕红色,不透明,四面体型,辐射对称,三裂缝.接种6 d左右孢子萌发,萌发类型为紫萁型(Osmunda-type),原叶体发育为铁线蕨型(Adiantum-type).接种25 d左右片状体形成.接种50 d左右发育为成熟原叶体,呈心脏形,裸露无毛状体.接种60 d左右性器官出现,雌雄同株.精子器长圆球形,由3细胞构成;成熟颈卵器颈部由4列细胞组成,3～5层细胞高.

| Abstract: | The spores of Adiantum malesianum Chatak were cultured in 1/2MS medium.The spore germination and gametophyte development were observed by light microscope.The results showed that the mature spores were brown-red,opaque,tetrahedral type,actinomorphous,trilete.The spores germinated about six days after sowing.The spore germination belonged to the Osmunda-type,while the gametophyte development was of the Adiantum-type.The prothallial plates formed about 25 days after sowing.The mature cordate prothallus develo... |
