THE STATE OF KEY ENZYMES IN ANTIOXIDANT SYSTEM OF PROTECTION IN PEACH LEAVES WITHIN IMMUNOINDUCERS IMPACT

As a result of studying the immune-inducing action of albite, immunocytophyte and ecogel, there was established their stimulating effect on the activity of key enzymes in the antioxidant system in peach leaves. The nature of the response of catalase and total peroxidase to the effect of these preparations was independent on the weather conditions. The degree of inducing effect was determined by the properties of the studied immunoinducers. The maximum stable growth of enzymatic activity was observed after peach treatment with albite and ecogel in its pure form and together with the fungicides. The growth of enzymatic processes intensity on the effect of immunoinducers is an adequate indicator of their stimulating effect.
