The presawing treatment of wheat seeds by lectin specific to the plant and its compositions with gapten and nitrogen fixation bacteria on the change in enzyme activity of antioxidant system of plant protection (peroxydase and katalase), endogenous lectin activity and flavonoid content in wheat leaves was studied in vegetation experiments. It is shown, that different biochemical links of protection plant system are activated, i.e. lectin activity in leaves increases 1.3 to 1.5 times, peroxydase activity and katalase activity rises 1.5 times and 5.0 to 8.0 times respectively and flavonoide content in leaves of vegetating plants increases under normal conditions of plant growth at the influence of factors of lectin nature.

Key words: lectin, wheat, lectin activity, flavonoids, peroxydase, katalase, plant-bacterium composition, gapten.
