紫花苜蓿、扁蓿豆POD同工酶的测定

Studies on Peroxidase Isozyhes in Medicago Sativa Cultivars and Medicago Ruthenica Cultivars.

利用聚丙稀酰胺垂直平板凝胶电泳技术，对十一份紫花苜蓿材料及十一份扁蓿豆材料进行了ＰＯＤ同工酶分析。结果表明，不同来源地的紫花苜蓿、扁蓿豆种内ＰＯＤ同工酶谱带数及其活性都有差异，相对迁移率趋于一致，而来源于山东西北部的五份苜蓿材料和来源于内蒙东部的二份扁蓿豆材料，其ＰＯＤ同工酶谱带分别相同，显示了ＰＯＤ同工酶的特异性与它们生活的特殊生境相适应。

The peroxidase(POD)isozymes in eleven Medicago sativa types and eleven Medicago ruthenica types were analysed and compared using polylamide gel electrophoresis tech-nique,It showed differences in the number of POD isozyme bands and the activity of POD isozyme in different types of M. sativa and M. ruthenica. Relativa mobility tends towards the same whereas POD isozymes in five types of M. sativa came from north-west region of Shandong Provice and two types of M. ruthenica camefrom east region of Inner Mongolia are siniliar.It showed POD isozyme specificity was in accordance with the specific habitat.
