ABSTRACT
The paper presents the influence of culture medium pH on the peroxidase and catalase activities in Monilinia laxa (Aderh.&Ruhl.) Honey parasite on plum. The fungus was cultivated “in vitro” on Leonian medium, different concentrations of hydrogen ions being achieved by means of appropriate buffers. The peroxidase and catalase activity was determined from mycelium and culture liquid culture at 7 days and 14 days after inoculation. Experiment consisted of three consecutive measurements and showed that oxidoreductase activity was inffluenced by the culture medium pH and culture age.
