渐尖毛蕨和齿牙毛蕨的配子体发育研究
Observation on the gametophyte development of Cyclosorus acuminatus and C. dentatus
摘要
Abstract
The spores of Cyclosorus acurninatus and C. dentatus were cultured in the mixed soil. Their spore germination and gametophyte development were observed by microscope. The result shows that spores of both species are dark-brown, monolete, semicircle-shaped in equatorial view and elliptical in polar view. The spores of C. acuminatus germinate faster than those of C. dentatus. Germination of both species is of the Vittaria-type. Filamental stages of both species are developed. Few hairs can occur on margin of the prothalli of both species. The mature prothalli of both species are cordate. Gametophyte developing time from prothalli to sporophytes differs between both species.This paper accumulates detailed information for gametophyte development of Cyclosorus and provides conditions for systematic classification of pteridophyte.关键词
