Physiologo-biochemical and optical determinants of leaves in wheat plants at different technology of herbicides application

The authors studied the influence of herbicides and mixtures of herbicides and biostimulators on the physiological and biochemical indices in plants of wheat and weeds. The possibility of combined application of the antistress preparation and herbicides during treatment of seed-growing and commodity wheat sown area for the purpose of the increase of crop capacity and ecologization of herbicides application was discussed. It was shown, that the use of herbicides together with natural regulators of plant's growth permit to increase the synthesis intension, the activity of chlorophyll-protein complexes lectins, functional activity of nucleic acids and optical properties of leaves, that promote to the plant's adaptation to stresses and the rising of crop capacity.
