摘　　要：桤木属为非豆科固氮树种,能改良土壤,适应性强,具有重要的生态价值。本文概述了桤木属植物在系统发育、染色体、同工酶与RFLP、RAPD、AFLP、SSR分子标记水平上的、包括亚属分类、倍性问题、不同桤木种的群体遗传多样性、遗传结构以及系统地理学等方面的研究进展,并探讨了现有研究中的存在问题,以期为桤木属植物进一步的遗传改良提供参考。As nitrogen fixation trees of non-Leguminosae,Alnus was becoming an ecologically valuable genus of plants for its ability in soil improvement and adaptation.In this paper,the research progress was reviewed and discussed on phylogeny and genetic variation on the level of chromosome,isozymes,RFLP,RAPD,AFLP and SSR in Alnus,including subgenus taxon,cytology,population genetic diversity and structure,phylogeography,and so on,with the expectation to provide references to genetic improvement of Alnus in future.
