摘 要 ：简要介绍了蕨类植物的生态类型和生殖方式;回顾了近年来分子标记技术在蕨类植物遗传多样性研究中的应用,主要包括种间亲缘关系和分类学的研究、遗传变异和遗传结构的研究,以及系统发育地理学方面的研究。最后,对蕨类植物遗传多样性研究中存在的一些问题进行了讨论和展望。

Abstract:Pteridophytes are the second-largest group of vascular plants,and understanding its genetic diversity could provide scientific basis for both conservation and utilization.In this paper,we briefly introduced the reproductive mode of pteridophytes and summarized the application of molecular methods in the researches of genetic diversity emphatically.It included three aspects: species relative and classification,genetic diversity and genetic structure,and molecular phylogeography.Finally,The problems in the current researches were discussed and nearfuture perspectives on the subject were put forward.
