Correlation between Hydrolytic Enzymes Activity, Geographical Origin and Pathogenicity of Some Isolates of Fusarium oxysporum f. sp. albedinis - Pharmacy & Pharmacology Research

The 20 isolates of Fusarium oxysporum f. sp. albedinis (Foa) produce amylase and cellulase enzymes, with the development of lysis zones around the inoculum (clear region) on the selective medium, indicates starch hydrolysis and cellulose degradation, with a variation in the ability of the isolates to produce these two enzymes, and this after measuring the diameters of the lysis zone. After
Principal Component Analysis (PCA), we found that there is a strong positive correlation between mortality rate and amylolytic activity CP 1 (74.80%) on the one hand and a weak correlation with cellulase CP 2 (22.3%), on the other hand. While, there is no correlation between the pathogenicity of the isolates and the geographical origin of the isolate or cultivar from which this isolate was isolated P=0.3042.
