The effect of temperature and age of strains of Fusarium oxysporum on its enzymatic activity.
The activities of pectin-methyl-esterase, polygalacturonase, cellulase, amylase, saccharase, and protease of strains of Fusarium oxysporum (Schlecht.) f.sp. pisi (Linford) were studied. The selected strains showed different symptoms and different degrees of pathogenicity on the host plant. The measurements were performed during the growth of strains at constant temperatures and, in another experiment, on the day at different temperatures at which the individual strains were grown. Activities were determined by the plate methods and by the spectrophotometric method. It has been found that enzyme activity of the strains with different degree of pathogenicity show considerable differences in dependence on temperature and growth dynamics.
