【摘要】 采用聚丙酰胺凝胶电泳法分析了产地为阿尔山和根河的兴安落叶松L1和L2、华北落叶松L3和长白落叶松L4种子中的4种酶的同工酶。结果表明:4个样品的POD、EST、SOD和AMY同工酶均为多态;同工酶带数目多少为EST>POD>SOD>AMY;同工酶带数目排列是L2>L4>L1>L3。在进化程度上,华北落叶松较为原始,长白落叶松居中,产于根河的兴安落叶松为较进化类型。聚类分析表明长白落叶松与华北落叶松亲缘关系较近,与兴安落叶松较远;华北落叶松与兴安落叶松和长白落叶松亲缘关系均较近。更多还原

【Abstract】 Four isoenzymes among the seeds of Larix gmelini(Rupr.) from Aershan(L1) and Genhe(L2), L. principis-rupprechtii Mayr.(L3)and L. olgensis Henry(L4)were analysed by means of polyacrylamide gel electrophoresis. The results showed that the isoenzymes of POD, EST, SOD and AMY in four samples wer all polymorphic. The mumber of the isoenzymes bands showed following tendency:L2>L4>L1>L3 . To extent of evolution, L. principis-rupprechtii is more original, L. olgensis is medial and L. gmelini from Genhe belonged to the type of evolution. The result of cluster analysis showed that L. olgensis had a closer relationship with L. principis-rupprechtii, and had a further relationship with L. gmelini. L. principis-rupprechtii had relatively close relationship with L. gmelini and L. olgensis.更多还原
