采用聚丙烯酰胺凝胶电泳法，检测了引自德国的８个白三叶品种及在中国西部收集的７个白三叶地方品种的酯酶和过氧化物酶同功酶。结果表明，在过氧化物酶同功酶位点，德国白三叶品种与中国西部白三叶地方品种之间遗传差异甚小，表现出相当高的同源性；在酯酶同功酶位点，德国白三叶各品种之间、中国西部白三叶７个地方品种之间以及德国白三叶与中国西部白三叶地方品种之间，都表现出较大的差异，且德国白三叶在酯酶同功酶位点有其独特的遗传基础。 Polyacrylamide gel electrophoresis was used to detect esterase and peroxidase isoenzyme in eight white clover cultivars from Germany and seven white clover locust cultivars collected in western China. The results showed that at the isoenzyme site of peroxidase, there was little genetic difference between white clover and white clover in western China, showing a high homology. In esterase isozymes Point, between the white clover varieties in Germany, white clover in western China 7 local varieties and between white clover and white clover in western China showed significant differences, and the German white three The esterase isozyme site has its own unique genetic basis.
