摘要
棉花可以通过乙酰—丙二酸途径、乙酰—甲羟戊酸途径和莽草酸途径合成一系列具有抗虫活性的次生物质,从而对害虫有不同程度的抗性。本文评述了棉花次生代谢物质的种类、抗虫活性、合成途径和影响因素,提出了充分利用次生代谢物质防御棉花害虫侵害的策略。
During the long process of evolution, plants have adapted to their environments through the biosynthesis of secondary metabolites （SM） using the acetate-malonate pathway, mevalonic acids pathway, or shikimic acid pathway, leading to resistance to different pests. As a major cash crop, cotton can produce many secondary metabolites with insecticidal activity, and show self-de- fense mechanisms under biotic stress conditions. These characteristics of cotton ensure reduced pest incidence and maintenance of ecological balance. This paper discusses the types of SMs, their synthesis, and insect resistance of cotton secondary metabolites in relation to their defense function. We propose possible pest-control strategies using secondary metabolites in cotton.
