同形鳞毛蕨成精子囊素系统的初步研究

研究了同形鳞毛蕨成精子囊素对该种和水蕨孢子萌发和配子体发育的影响，结果表明：同形鳞毛蕨配子体能产生成精子囊素，该成精子囊素能抑制同种孢子的萌发，抑制作用随配子体成熟度的增加而增强；同形鳞毛蕨成精子囊素还可促进同种孢子发育为雄配子体；光照条件下，同形鳞毛蕨成精子囊素对水蕨孢子萌发和配子体发育影响不大，黑暗条件下，同形鳞毛蕨成精子囊素能显著的促使水蕨孢子提早萌发，但都不影响其孢子最终萌发率和配子体的性别分化，表明同形鳞毛蕨和水蕨的成精子囊素不属于同一系统。

Primary Study on Antheridiogen System of Dryopteris uniformis

This paper mainly studies the antheridiogen system of Dryopteris uniformis, which affecting the spore germination and gametophyte development of D.uniformis and Ceratopteris thalictroides. The result shows that: the gametophytes of D.uniformis can form antheridiogen, which could restrain the spore germination percentage of its own species. The restraining action of antheridiogen to the spore germination becomes stronger as the gametophyte grows more mature. Antheridiogen of D.uniformis can promote male gametophyte formation of itself. In the light, the antheridiogen of D.uniformis have no obvious influence on spore germination and gametophyte promotes C.thalictroides. However, in the dark situation, the antheridiogen of D.uniformis promotes spores to germinate much earlier. However, it does not make any influence on its ultimate germination percentage and sex differentiation. The present study indicated that the antheridioen system of D.uniformis differs from that of C.thalictroides.
