Botrytis cinerea young culture filtrate and both ethanol precipitate and following it polygalacturonase were found to be good elicitors of peroxidase, beta-1,3-glucanase and chitinase in bean leaves. These elicitors superimposed individually on the primary leaves caused an increase in activity of examined enzymes both in the leaves treated directly and in those which developed after an inoculation with B. cinerea. Polygalacturonase and crude mixture of filtrate components elicitated these enzymes similarly. Polygalacturonase caused an increase of activity in 3 more firmly bound to column of five peroxidase fractions separated on ConA-Sepharose. Chromatography on DEAE-Sepharose showed that polygalacturonase induced anionic peroxidase selectivity
