运用聚丙烯酰胺凝胶电泳，测试了采自四川南川县金佛山不同生境的多辐溲疏５个居群５０株个体的过氧化物酶同工酶，对酶谱带位置进行了二态编码，然后采用Ｒｏｇｅｒｓ－Ｔａｎｉｍｏｔｏ，Ｓｏｋａｌ－Ｍｉｃｈ－ｅｎｅｒ，Ｓｏｋａｌ－Ｓｎｅａｔｈ，Ｊａｃｃａｒｄ等结合系数用组平均法（ＵＰＧＭＡ）对各谱带位置进行了聚类分析．结果表明，相同生境同一居群内的个体间表现出较大的遗传同质性，而来源于不同生境的不同居群个体间却呈现出较大的遗传趋异性；同时，５个居群不但具有许多共同谱带，而且整体相聚的结合系数大多超过０．５，这表明５个居群在很早以前可能是属于同一大居群，在长期进化过程中，由于微生境的地理与气候因子选择，使得多辐溲疏现仅在金佛山海拔６００～１２００ｍ的约ｋｍ２范围内呈岛状分布；又由于其特殊的繁殖方式——居群内个体虽能杂交，但因该种仅能正常开花传粉，大部分种子败育，使得居群内个体遗传变异性不能通过有性生殖方式固定下来，仅能通过营养繁殖方式繁殖后代，而正是营养繁殖导致了居群内较大遗传同质性以及居群间的遗传趋异性．在整个进化过程中生境只不过是对那些遗传变异起到了选择固定作用
Polyacrylamide gel electrophoresis was used to test the peroxidase isozyme of 50 individuals from 5 populations in different habitats of Jinfo Mountain in Nanchuan County, Sichuan Province. Then cluster analysis was performed by group average method (UPGMA) with Rogers-Tanimoto, Sokal-Mich-ener, Sokal-Sneath, Jaccard and other binding coefficients. The results showed that individuals in the same habitat in the same habitat showed greater genetic homogeneity, while individuals in different habitats derived from different habitats showed greater genetic divergence. At the same time, the five populations not only Which have many common bands and mostly converge more than 0.5, indicating that the five populations may belong to the same large population long ago. In the long-term evolutionary process, due to the geographical and climatic factors Selection, so that more convergence is only in Jinfushan 600 ~ 1200m above sea level km2 range was island-like distribution; and because of its special breeding methods - although the population can hybridize individuals, but only normal Flowering and pollination, most of the seeds abortion, making the individual genetic variability within the population can not be fixed by sexual reproduction, only by means of vegetative propagation of offspring, and it is nutrition breeding led to larger genetic homogeneity Sex and genetic divergence among populations. Habitat is just a matter of choice and fixedness for those genetic variations throughout the evolutionary process
