Abstract

The effects of enzymatic preparations—pectomacerin, hemicellulase, and Trichoderma viride 13/10 cellulase—on plant immunological status were studied using two pathosystems, carrot root–white rot agent (Sclerotinia libertiana) and carrot root–black rot agent (Rhizopus nigricans) as examples. It was demonstrated that these preparations reduced the plant damage by infections, namely, decreased the permeability of cell membranes in the infected tissue and stimulated its defense responses, which were expressed as a stable elevation in the content of phenolic compounds and formation of tissue protective barriers.
