许多研究表明,水稻对褐飞虱的抗性与稻株体内的游离氨基酸、可溶性糖、d—氨基丁酸、组胺以及草酸等成份的含量有密切关系。其中,前两种成份是褐飞虱生长发育所必需的营养物质,故在抗虫品种中的含量低于感虫品种;而后几种成份对褐飞虱或起毒性作用、抑或产生拒食性,因此,在抗虫品种中的含量又总是高于感虫品种。但是,对于参与到植物细胞的氧化过程和保卫 Many studies have shown that the resistance of rice to BPPH is closely related to the contents of free amino acids, soluble sugar, d-aminobutyric acid, histamine and oxalic acid in rice plants. Among them, the first two components are the necessary nutrients for the growth and development of N. lugens, so the content in insect-resistant varieties is lower than that in susceptible varieties; and then the several components play a toxic or antifeeding effect on N. lugens, therefore, Insect species in the content is always higher than susceptible varieties. However, it is involved in the oxidation and defense of plant cells
