近年来报导感抗品种对稻飞虱抗性与稻鞘内有机酸和氨基酸含量有关。国际水稻所和湖南农学院前后已报导稻飞虱取食量与稻株内谷氨酸、天冬酸和门冬酰胺等成显著相关。一九八○年我们对在福州种植条件下的主要感抗品种(包括田间稗草)进行稻飞虱抑食和氨基酸、有机酸相关性测定。兹将结果整理如下。
In recent years, it has been reported that the resistance of resistant varieties to planthoppers is related to the content of organic acids and amino acids in rice sheath. International Rice Research Institute and Hunan Agricultural College reported that the feeding amount of planthoppers was significantly correlated with glutamic acid, aspartic acid and asparagine in rice plants. In 1980, we measured the inhibition of planthoppers and amino acids and organic acids on the main susceptible cultivars (including barnyardgrass) under the planting conditions in Fuzhou. I will organize the results below.
