| Abstract: | The effects of medium types,pH value and temperature on microsclerotium formation were investigated by using Verticillium dahliae strain XJ2008 as experiment material.The optimum condition was established and used to test the microsclerotium formation of 15 V.dahliae strains collected from Xinjiang,Jiangsu,Henan,Shaanxi and Shandong.Results showed that the medium for microsclerotium formation in large scale was basal agar medium modified(BMM),with pH ranging from 9.5 to 11.5 and temperature of 20℃.Under this condition,15 strains could produce abundant microsclerotia after inoculation for 12 days.The quantity and size of microsclerotia among the 15 strains have significant difference,and they bear no relationship with the pathogenicity of the strains. |
