摘　　要：纯化的HMC毒素对C细胞质玉米幼根生长的抑制,根电解质的渗漏,叶片和植株的伤害,超氧物歧化酶和过氧化物酶活性及原生质层透性的影响,与基因型相同的T、N细胞质相比,差异显著,进一步确定了HMC毒素对C细胞质的专化作用。There are significant differences between Tor Nand C cytoplasm in theresponses to purified HMC—toxin including seedling root growth inhibition,electrolyte leakage of root,harm to leaves and plant,influences to theactivities of superoxide dismutase and peroxidase and permeability of proto-plast laycr to noneletrolytes etc.All the results suggest that HMC—toxinis a host—specific pathotoxin to C—cytoplasm.
