新疆冷蕨属孢子形态研究

Study on the Spore Morphology of CystopterisBernh.in Xinjiang

对新疆冷蕨属３种孢子形态进行了研究，结果表明，冷蕨孢子周壁纹饰大致分为刺状、疣状和脊状隆起，可作为分种依据。并结合其它特征讨论了分布规律和孢子形态的演化趋势。

Thesporesof3 speciesofCystopterisBernh in Xinjiang havebeen studied un- der LM and SEM.The results show that the perine sculptures of spore m orphology of Cystopteriscan be divided into 3 types thorny,cristate and verracate.They can be used for groundsofdividing species.Combining othercharaetres,the law ofdestribution and theevolu- tionary ofsporesin thissection arediscussed.
