| 摘 要： | 对影响水稻对褐飞虱生物型Ⅱ抗性水平的主要抗原次生化合物，即HPLC谱图中的4个谱峰（峰1、峰2、峰8、峰12）对应的次生化合物的含量变化及其对抗性的影响进行了研究。结果表明，某些品种不同苗龄稻株对褐飞虱生物型Ⅱ的抗性差异，极可能就是这4个相关抗原次生化合物在不同生育期的含量变化所致；与水稻植株其他部位相比，这4种抗原次生物质在叶鞘中的含量最低。这也许是褐飞虱喜欢聚集在叶鞘部位取食的化学因素之一。

| Abstract: | Content variations of the four components affecting rice resistance to the brown planthopper(BPH) biotype Ⅱ in rice plants and their influences on rice resistance to BPH were investigated.The resistance diversity of rice to BPH biotype Ⅱ at different plant ages was chiefly attributed to the content variability.And the contents in the leaf sheath were the lowest as compared with those in other parts.It might be one of the reasons why BPH has a preference of feeding on leaf sheath aggregately from chemical point of view. |
