赖草属七个种同工酶研究

用聚丙酰胺凝胶电泳法对赖草属７个种的幼根、幼叶进行了酯酶、过氧化物酶同工酶分析，结果表明：无论从相同器官进行不同的同工酶分析，还是从不同器官进行相同的同工酶分析，这７个种的酶谱在各带区存在相似酶带，但更多的是相异酶带。从酯酶、过氧化物酶这两种酶分析结果来看，酯酶比过氧化物酶分离效果好些；从幼根和幼叶这两个器官的酶谱来看，幼根比幼叶酶带多些，分离效果也好些。同时也表明这７个种的酶谱变化与染色体倍性变化无关

THE STUDY ON ISOZYMES OF SEVEN SPECIES IN LEYMUS

The esterase and peroxidase isozymes for seven species of Leymus in young roots and young leaves were studied by means of polyarcylamide electrophoresis. The results showed that these 7 species shared less isozymes, but more were difference. From molecular level, this study supported these 7 species are valid. As far as same organ is concerned, the esterase isozyme is better than peroxidese in Leymus. As same isozyme was used, zymogram patterns of young roots are better than those of young leaves, the variation of zymogram patterns has not related to variation of chomosome number.
