Abstract
The pectic enzymes produced by Fusarium oxysporum f. lycopersici appear to be causally related to the virulence of the pathogen. The effects of various cultural conditions on the synthesis of pectin methylesterase by two strains of the pathogen were investigated. The virulent strain grew better and produced more pectic enzymes than the avirulent one, and this difference became even more pronounced in media with high pectin content and when the temperature of incubation was raised from 15° to 28 °C. The correlation between the virulence of the pathogen and the production of the pectic enzymes is discussed.
