摘要
对蝉拟青霉进行UV诱变处理,比较诱变前菌株3L和诱变后M1、M2、M3及M4各个菌株对白粉虱的致病性和菌生理特性的变化情况,并进行相关性分析。结果表明,菌株的几丁质酶活性、孢子萌发率及生长势与致病性有密切的相关性;而产孢量、蛋白质酶活性则与致病性的关系不大。
After Paecilomyces cicadae was mutated by ultraviolet comparative studies on the relativity of physiological characters and pathogenicity about the original strain (3L) and mutant strains(M1,M2,M3,M4) were made.The results show that there is a close relation between pathogenicity of fungus to insect and activity of chitinase, germination rate and velocity of growth.But the number of productive spore and proteinase is less related with pathogenicity.
