| 摘 要： | 采用聚丙烯酰胺凝胶电泳的方法, 获得了金华北山苔藓植物19 个种之间酯酶(EST)、超氧化物歧化酶(SOD)的同工酶酶谱。将19 个种苔藓植物的酶谱进行量化后, 采用主成分分析(PCA)方法, 比较了19 个种种间关系的差异特点。研究表明, 苔藓植物具有很高的遗传多样性, 以同工酶酶谱资料为基础, 应用主成分分析方法能够比较直观和有效地反映出苔藓植物分类群间的系统关系。

| Abstract: | By polyacyacrylamide get electrphoresis, two isozymes: Esterase(EST)and Superode dismutase(SOD)of 15 species of Musci and 4 species of Hepaticae were studied. Zymogramatic differences of two isozymes in 19 species were numerically revealed by Principal Component Analysis (PCA). The results showed as follow:1)Bryophytes are of high genetic diversity; 2)Based on isozyme data, PCA could be applied to reveal the systematic relationships among different bryophyte species in genetic level. |
