Effect of pretreatment of spring wheat seeds by lectin and lectin-bacterial composition on the physiological indexes of plant development and productivity

The effect of exogenous lectin and its composition with nitrogen-fixing bacteria Azotobacter chroococcum T79 on the contents of chlorophyll and carbohydrates in the leaves of plants, formation of vegetative mass, grain productivity of wheat and nitrogenase activity of the rhizospheric microorganisms have been investigated. It was shown, that pretreatment of seeds by lectin and lectin-bacterial composition promoted the increase of chlorophyll and carbohydrates in the leaves, nitrogenase activity of the rhizospheric complex of microorganisms as well as accumulation of plants biomass and grain productivity of spring wheat.
