应用聚丙烯酰胺垂直平板电冰对起源于我国的12个葡萄野生种过氧化物酶同工酶进行测定,结果表明:葡萄属内每个种在酶带数目、酶活性强弱方面都显示种的特异性,这种特异性有相对的稳定性.遗传距离系数分析表明,凡起源相近、亲缘关系较近的种类,其距离系数 D 明显较小.这为利用同工酶进行分类和进化提供了启示.
The polyacrylamide vertical plate ice was applied to determine the peroxidase isoenzyme of 12 grapevine species originated from China. The results showed that each species in the genus Vitis showed the number of bands and the activity of enzymes , And the specificity is relative stability.The analysis of genetic distance coefficient shows that the distance coefficient D is obviously smaller for those species with similar origin and close genetic relationship.This provides the basis for the classification and evolution using isozyme Inspiration.
