谷精草属六个种的同工酶聚类分析

Bidigical science and technoligy cluster analysis of six Eriocau species based on isozyme

本文对谷精草属6个种的POD、EST、MDH和AMY同工酶分别进行了电泳分离,采用STATISTICA/W4.5软件对酶谱的不同相似性系数进行聚类分析,进而绘出树系图。同工酶酶谱及其聚类分析的结果与现有的形态学分类系统基本相符,首先将E.sexangulare Linn.、E.alperstre与E.buergerianum分为一支,将E.kunmingense Z.X.Zhang、E.nepalense Prescottex Bongard与E.cinereum R.Brown并为一支,且它们是平行进化的关系。在第一支中,E.alperstre与E.buergerianum亲缘关系更近。

Four isozyme (POD, EST, MDH, AMY)of Eriocaulon Linn. have been studied in this article. And we analyse the result of electrophoresis by using STATISTICA/W 4.5. After that, we obtain a tree diagram of these 6 species. The result of cluster analysis about isozyme,comparing with morphology study, supports the view that E. sexangulare Linn.,E. alperstre and E. buergerianum should be put into one group,while E. kunmingense Z. X. Zhang, E. nepalense Prescott ex Bongard and E. cinereum R. Brown for another. What s...
