摘　　要：对大豆疫霉菌胁迫下抗感不同野生大豆根、茎、叶中过氧化物酶(peroxidase,POD)活性的变化进行了初步研究。结果表明:抗病野生大豆接种后叶中POD活性在病程的大部分阶段高于感病野生大豆,同时高于未接种植株;而根和茎中的POD酶活性在病程的大部分阶段有所增加,但变化幅度不大。Phytophthora root and stem rot caused by Ph^ophthora sojae is a world wide destructive soybean disease,it may at- tack plants at any growth stage, causing root and stem rot. The principle of POD activity changes in roots, stems and leaves of soybean varieties with different resistance to Phytophthora sojae and the effect of POD on resistance to this disease were re- searched. The results showed that the POD activities of leaves in resistant soybean varieties increased compared with the sus- ceptible soybean varieties at most of the pathogenicity stages, and it was also higher than that of control. The reaction of POD in roots and stems increased at most of the pathogenicity stages, however, the change extent was relatively low.
