利用聚丙烯酰胺凝胶盘状电泳法,对13种牧草在萌芽期进行了过氧化物酶同工酶分析。结果发现,过氧化物酶同工酶与牧草抗寒性的关系极为密切,抗寒性在酶区带条数上得到明显反映,区带条数多的材料抗寒性强。
By using polyacrylamide gel electrophoresis, peroxidase isoenzyme analysis of 13 species of grass was conducted during germination. The results showed that the relationship between peroxidase isoenzyme and forage resistance was extremely close, the cold resistance was obviously reflected in the number of enzyme zones, and the number of zones with more bands was more resistant to cold.
