摘要: Content variations of the four components in the plants of rice ASD7, IR36 (resistant to brown planthopper) and TN1 (susceptible to brown planthopper), and their influence on rice resistance to brown planthopper (BPH, Nilaparvata lugens) were investigated. The resistance diversity of rice to BPH biotype II at different plant ages was chiefly attributed to the content variability of the secondary compounds. The contents in the leaf sheath were the lowest as compared with other parts of rice plant. It might explain the reason that BPH has a preference for feeding on leaf sheath aggregately from chemical point of view.
