用聚丙烯酰胺凝胶电泳法对鹅观草、大麦及其属间杂种的幼根、剑叶和幼穗进行了酯酶同工酶分析,结果表明:不同器官的酯酶同工酶谱表型有明显差异。鹅观草和大麦同—器官酶谱差异较大,表现在酶带数目、分布区域、酶带迁移和酶的活性上。佐证了鹅观草与大麦的亲缘关系较远。杂种F_1酶谱主要表现为互补两亲本酶谱的模式,并且有偏向母本遗传的倾向。 Esterase isozymes were analyzed by polyacrylamide gel electrophoresis on the young root, the flag leaf and the young panicle of the hybrid between G. gossypii, barley and their genera. The results showed that: There are obvious differences. Eupatorium and barley with - organ zymogram differences, manifested in the number of enzyme bands, distribution area, the enzyme band migration and enzyme activity. Proved Goose grass and barley more distantly related. Hybrid F_1 zymogram mainly showed the pattern of complementary amphipathic zymogram, and tended to bias the female parent.
