The paper reviewed traits and genetic rules of cotton against verticillium wilt in general , depicted the three approaches which exists in cotton defending against verticillium wilt through reinforcing physical structure , producing plant phytoalexin , interacting with microbes in detail 摘要本文概述了棉花抗黄萎病的特点与规律，指出棉花植株是通过自身组织结构的强化、植物抗毒素的合成以及微生物之间的互作三方面应对黄萎病菌的侵染。
Producing plant phytoalexins has been recognized as the primary and dominant routines in defending system in cotton , include terpenoid , proteases and hormones in which many enzymes , such as chitinase , has been proved useful against verti - cillium in several plants , but not their functional mechanism 在棉花抗病反应中以植物抗毒素的合成为主要途径，包括萜类、酶类和激素类3类化学物质，其中酶类物质如几丁质酶已经在很多植物中被证明具有抗病作用，但是其具体作用途径仍不清楚。
Phytoalexins are low molecular weight chemicals that plants produce and accumulate in response to infection especially of fungal origin . sakuranetin is a kind of flavanone phytoalexin isolated from ultraviolet - irradiated rice leaves . recent research work on flavanone phytoalexins represented by sakuranetin is reviewed . interesting novel structures , stucture - activity relationships and synthetic methods are discussed 植物抗毒素是植物受到外界病原微生物侵扰后所产生并积累的一类具有抗菌活性的小分子物质,樱花素是从水稻稻瘟病感染组织中分离鉴定的一种黄烷酮类植物抗毒素.对以樱花素为代表的水稻抗毒素及其类似物的结构与活性、黄烷酮类植物抗毒素合成方法的研究概况进行了综述
