| 摘要: |
| 用聚丙烯酰胺凝胶电泳技术对淫羊藿属植物10个种(含7个大花种和3个小花种)32个幼叶样品的谷草转氨酶同工酶进行了研究。结果发现,谷草转氨酶同工酶酶带共15条。不同物种的酶带数为2～15条,不同植株的谱带数为2～10条。种间存在明显差异,可以作为物种鉴定的辅助依据。 |

| Abstract: |
| The glutamate oxaloacetate transaminase isozyme in 32 young leaf samples of 10 species of Epimedium(including 7 species of the big-flower group and 3 species of the small-flower group)were studied by means of polyacrylamide gel eletrophoresis(PAGE). The results showed that 15 bands of glutamate oxaloacetate transaminase isozyme were discovered in all accessions,likewise,2-15 bands in different species and 2-10 in different plant individuals,showing that zymographs among species were obviously different. Therefore,this could be an auxiliary evidence for the species identification. |
