摘　　要：为了进一步研究空间诱变对蒙农杂种冰草生物学效应的影响,以空间诱变冰草F1植株为材料,对诱变后冰草的过氧化物同工酶和酯酶同工酶谱带的变化情况进行研究。结果表明:10株空间诱变蒙农杂种冰草株系和对照冰草之间表现出一定的遗传性,每一株空间诱变蒙农杂种冰草都有自己的变异酶带;对照冰草有6条过氧化物同工酶酶带,诱变冰草的酶带数从3条到8条不等,大部分酶带强度趋于减弱;对照冰草有8条酯酶同工酶酶带,诱变冰草的酶带数从3条到10条不等,大部分酶带强度趋于减弱。In order to further study the effect of space mutation on biological effect of Mengnong hybrid agropy- ron,the space mutation wheatgrass F1 generation plants were used as materials, the change of POD and EST isozymes bands were studied. The results showed that there was certain genetic between 10 lines of space muta- tion Mengnong hybrid agropyron lines and control,each space mutation strain had variant enzyme bands itself; The contro had six POD isozymes bands, and they were in the ranging from three to ten of space mutation Mengnong hybrid agropyron,the strength of most bands tend to wesken; The contro had eight EST isozymes bands,and they were in the ranging from three to ten of space mutation Mengnong hybrid agropyron,~the strength of most bands tend to wesken.
