【摘要】 从形态抗蚜性、生化抗蚜性和诱导抗蚜性等 3个方面总结了棉花对棉蚜抗性机制的研究进展。其中 ,形态抗性来源于叶片茸毛等一些主要物理性状 ,生化抗性则与单宁类、萜烯类化合物等次生物质以及氨基酸、可溶性糖等营养物质有关 ,而诱导抗性主要通过为害胁迫和外源刺激 2种途径诱导产生。文章还对棉花部分形态抗蚜性状遗传机制的研究做了概述。这些研究为深入利用棉化的抗蚜性从而达到控制棉蚜的发生提供了依据更多还原

【Abstract】 Mechanisms of the morphological,biochemical and induced resistance of cotton to Aphis gossypii is summarized.Morphological resistance gets from hairiness of cotton leaves and some other physical characteristics.Biochemical resistance is related to secondary substances such as tannin and terpenoids and nutrients such as amino acid and soluble sugar.Induced resistance is obtained by feeding stress or other external stimulation. The genetic mechanisms of some morphological characteristics are also introduced.更多还原
