摘要
本文从膜质过氧化反应及保护酶体系的变化、过氧化物酶、苹果酶脱氢酶同工酶的表达特性，分析了抗性不同的大豆品种对灰斑病１、７、８号小种的生理生化反应。研究结果表明：在灰斑病１、７、８号小种侵染下，感病品种膜质过氧化水平加重，保护酶体系失去活力，而抗病品种，虽然丙二醛（ＭＤＡ）含量有所增加，但膜质的保护酶系统活性都很强，植株受害较轻。而过氧化物酶、苹果酸脱氢酶同工酶的变化反应了品种对灰斑病的抗性，这两个同工酶的协同反应，标志着品种抗灰斑病的特性。
Abstract Physiological and biochemical reactions of different Soybean cultivars inoculated with FLS No. 1. 7. 8. were studied by means of study on change of memberanous peroxidatic reaction,Protective enzyme System, peroxidase and malic dehydrogenase isozyme. The results showed: the membranous peroxidatic reaction of susceptible cultivars was more serious after inoculated with FLS, and the activity of protective enzyme system became lost, The MDA content of resistant cultivars had some increase, but the activity of protective enzyme system was very active and disease infection on plants was not serious. The variation of reactivon of the isozymes reflected the degree resistance of the cultivars to FLS. The coordinate reaction of the demonstrated the nature of resistance of Soybean cultivars to FLS.
