Changes of defensive enzyme activities in different Agaricus bisporus varieties after inoculation with Mycogone perniciosa
Varietal resistance of Agaricus bisporus against Mycogone perniciosa was investigated.Four kinds of defensive enzymes,phenylalanine ammonia-lyase,peroxidase,catalase and polyphenol oxidase might induce A.bisporus to produce resistance against the pathogen.After inoculation the activity of four enzymes changed significantly.Among the strains of A.bisporus studied,W192 contained the highest amount of the four enzymes,then As2796 and As258 followed.
