1978年,曾试验比较了棉花黄萎病六种人工接种方法,其中,以土壤接菌结合棉苗伤根的方法较好。在此基础上,对山东省的黄萎病菌生理型做了鉴定试验。根据两个鉴别寄主——陆地棉岱字15号和海岛棉8763依的抗感反应,将测试的44个单孢菌系划分为三个不同的生理型。66.7%的菌系属于生理型I 号,分布山东各主要棉区。 In 1978, six methods of artificial inoculation of cotton Verticillium wilt were compared. Among them, the methods of soil inoculation combined with cotton seedling root injury were better. On this basis, the physiological test of Verticillium dahliae in Shandong province was done. Based on the anti-susceptibility responses of two identification hosts, Upland Cotton 15 and Upland Cotton 8, the 44 tested single-fungal strains were divided into three different physiological types. 66.7% of the strains belonged to the physiological type I, which distributed the major cotton areas in Shandong.
