Biochemical changes in the mycelium of two Rhizoctonia solani isolates during autolysis

Some biochemical changes occurring in the mycelium of two isolates (one pathogenic FR and another non-pathogenic GD2) of R. solani during autolytic phase of their growth were studied, by growing the fungi for periods longer than 210 days. During autolysis a decrease of 76.4% and 78.5% in mycelial dry weight occurred in pathogenic and non-pathogenic isolates respectively, compared to that at the beginning of autolysis. The mycelium of non-pathogenic isolate was more affected during autolytic phase of growth than that of the pathogenic isolate.
