摘要
半个多世纪以来，对棉花黄萎病抗病机制的研究取得了很大进展。棉花黄萎病抗病机制是很复杂的，既有棉株体固有的抗性，又存在病菌侵染诱发的抗性。棉株遭受黄萎病菌侵染后，以其内部形成一些胶状体、侵填体等物理障碍或产生一些植保素等生化障碍或两者同时发生的反应形式来表现抗性。
The study on mechanism of Verticillium wilt resistance in cotton has been made a great advance. The mechanism of Verticillium wilt resistance in cotton is very complex which include both the instinctive resistance in cotton plants and the induced resistance by Verticillium dahliae infecting. After cotton plants are infected by V. dahiiea, the formation of gums and tyloses and the eventual sealing-off of the infected vessels are occured in plants or phytoalexin are producted. Physical restriction wilt or chemical host response or both make contributions to expression of Verticillium tilt resistance in cotton.
