Efficiency of growth regulators with anti-stress properties in agricultural technology of winter wheat in the Middle Volga region

Abstract

The use of growth regulators with anti-stress properties Albit and Moddus was studied during winter wheat cultivation in the conditions of the Middle Volga region. During the study period, the effectiveness of biological products was high; in the autumn period, treatment with biological products allowed winter wheat plants to overwinter with less losses, to reduce the duration from germination to autumn tillering, to increase the number of shoots, the weight of plants and roots, the number of leaves and sugar content. The biostimulator Moddus has shown the effectiveness of action at the heading stage on such parameters as the content of sugars, starch and fibre in the leaves; at the stage of grain full ripeness – sugar, starch and fibre content in grain, yielding ability and realization of the yield potential. The antistressant Albit showed great efficiency by influencing such indicators as the duration of growing season, the weight of 1000 grains, the value of the activities of α-amylase, β-amylase and α + β-amylase.
