| 摘 要： | 光照强度和苗龄对水稻品种抗褐飞虱不同生物型的影响的研究结果表明，光照强度和苗龄对水稻品种抗褐飞虱不同生物型及不同生物型危害后稻株死亡速率的影响明显。但是，光照强度和苗龄对不同品种对褐飞虱不同生物型的抗性表现及植株死亡速率的影响程度并不完全一样。水稻品种对褐飞虱生物型Ⅱ和孟加拉型的抗性以及稻株死亡速率、品种和光照强度、品种和苗龄、光照强度和苗龄及品种、光照强度、苗龄3者间均存在明显的互作效应。

| Abstract: | Light intensity and seedling stage were found to have significant influences on the resistance of rice plants of different varieties to different biotypes of brown planthopper (BPH, Nilaparvata lugens) and on the speed of plant death after the damage by the pest. However, inter-varietal differences were observed in both respects. Interactions between variety and light intensity, between variety and seedling stage, between light intensity and seedling stage and among variety, light intensity and seedling stage were significant. |
