摘要:
对大豆胞囊线虫3号小种的抗病品种Hartwig和小粒黑豆，感病品种辽豆15和中黄28分别接种线虫，检测大豆根系中大豆胰蛋白酶抑制剂的表达量对大豆抗胞囊线虫的抗性。经过胰蛋白酶抑制剂活性测定结果表明，接种大豆胞囊线虫的抗感品种的大豆胰蛋白酶抑制剂（STI）表达量明显高于未接种的品种，各个品种的STI表达量也不同。说明大豆胰蛋白酶抑制剂参与抗病过程。但是各个品种的变化趋势并不相同，表明抵御线虫的抗病作用机制存在品种间差异。
Abstract:
The resistance of soybean trypsin inhibitor(STI) to the race 3 of soybean cyst nematode(Heterodera glycines Ichinohe，SCN)were studied by inoculating SCN to resistant varieties，Hartwig，Xiaoliheidou and susceptible cultivars，Liaodou 15，Zhonghuang 28.Results showed that the activity of STI with inoculation was higher than that without inoculation and the STI activity were also different among varieties.The dynamic trends of STI were varied with varieties.Results suggest that STI had attended the resistance of soybean to SCN and the resistant mechanism maybe different among soybeans.
