Effects on Trypsin Inhibitor in Roots of Resistant Soybeans after Heterodera glycines Invasion

The relationship of Soybean Trypsin Inhibitor (STI) and soybean resistance to Soybean cyst nematode (Heterodera glycines Ichinohe, SCN) were studied by two soybean resistant varieties and two susceptible soybean cultivars. The assay results showed that the activity of STI with inoculation was changed extensively in the soybean roots comparing with the no inoculation. A conclusion that STI had attended the resistance of soybean to SCN was drawn; but the trend curve of four varieties were not consistent, it would open out that there was some difference among four varieties, which were defended against the invading of SCN, that meant the different resistant mechanism in different soybeans.
