| 摘 要： | 研究了不同光照强度条件对水蕨孢子萌发以及配子体性别分化的影响。结果表明:2 000~4 000 lx的光照强度条件有利于水蕨孢子萌发,4 000 lx光照条件下孢子萌发最快。光照强度约为4 000 lx时最有利于使水蕨发育为两性配子体。光照强度约为1 000 lx时最有利于使水蕨发育为雄性配子体。为水蕨的人工栽培和分子生物学研究提供理论依据。

| Abstract: | The effects of different light intensities on spore germination and the growth of gametophyte of Ceratopteris thalictroides(L.) Brongn.were studied.The results showed that the intensity of 2 000~4 000 lx is suitable for spore germination,the optimum point is at 4 000 lx.When the intensity is around 4 000 lx,the spores easily grow into hermaphrodites gametophyte.When the intensity is around 1 000 lx,the spores mostly grow into males gametophyte.It gives evidence for the cultivation of C.thalictroides and the... |
