Biological Characteristics of |Beauveria bassiana Strains of Different Geographic Sources
|
Abstract:
Fifteen wild strains of Beauveria bassiana were collected and isolated from 10 regions of Jilin province.Their spore germination rate,colony diameter,sporulation and extracellular protease production level were compared.The results indicated that high spore germination rate strains were the conidia type,fast growing strains of colony type were the hyphae type,and strains′characteristics between the conidia type and the hyphae type were the mixed type,respectively.Protease activity test showed that there was no correlation between extracellular protease production level and colony morphology.In conclusion,the strains of D4-2-1 and CHL20 were potential strains for biological control.
