中文摘要: |
以棉花黄萎病菌Verticillium dahliae XJ2008菌株为试材,研究了培养基类型、pH值、温度等因素对棉花黄萎病菌微菌核形成的影响,确立了微菌核形成的最佳培养条件,并对采自新疆、江苏、河南、陕西、山东等地的15个棉花黄萎病菌菌株进行了测试。结果表明,适合于棉花黄萎病菌微菌核大量产生的培养基为基础改良培养基(BMM)、pH值为9.5-11.5、温度为20℃。在该条件下,15个大丽轮枝孢菌株在接种后第12天即可产生大量的微菌核,不同菌株产生微菌核的数量及大小间存在着显著差异,但均与病菌的致病性 |
英文摘要: |
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. |
