摘　　要：利用聚丙烯酰胺凝胶电泳技术，对内蒙古不同生境条件下生长的扁蓿豆的种子酯酶同工酶多样性进行了研究。结果表明，内蒙古地区扁蓿豆的种子酯酶同工酶酶谱具多样性；同一种或种下分类单位，由于材料来源不同，所表现的基本酶谱型与地理分布有关，基本上与草地区划中的地段相吻合。因此，在进行材料收集时应以地段为单位进行，而在地形单元和植被组合变化较大的地段需要配合地片进行。n the paper the esterase isozyme diversity of the different materials of Medicago ruthenica from different habitats in Inner Mongolia was studied using polyacrylamide gel electrophoresis. The results showed that: 1. The esterase isozyme polymorphism of M. ruthenica is high in Inner Mogolia region. 2. The zymographs of the same species or taxa which come from different areas were related to the geographic distribution of M. ruthenica, and it corresponded with the sectors in the grassland division. Therefore the collection of materials should in accordance with the sectors, but in the sector where has more divergent habitats, the work should be done according to the subsectors.
