INFLUENCE OF PREPARATIONS OBTAINED FROM CARBOXYMETHYLATED PLANT RAW MATERIALS ON GROWTH PROCESSES, YIELD AND BIOCHEMICAL PARAMETERS OF WHEAT GRAIN

Abstract

Studies of the effect of biological products obtained from carboxymethylated products of processing plant raw materials on the growth and development of spring wheat (pre-sowing treatment of seeds with an aqueous solution of 150 g per 1 ton of seeds per 10 L of water) showed that the studied drugs influenced the growth processes of the culture. The activation of the growth and development of wheat in the first phases was traced, from the germination of grain (the appearance of embryonic roots), to the formation of a more powerful tillering of the culture. The studied preparations contributed to an increase in wheat yield in a small-plot experiment by 30–43%, in a field experiment – by 15%, in production conditions – by 21–32%. An increase in wheat yield under the influence of growth regulators does not always accompany an increase in the protein and gluten content in the grain. The direction of the change in the protein concentration in grain towards a decrease (for example, according to the non-fallow precursor, in the presence of the limiting nitrogen factor in the soil) can be defined as the "growth dilution effect" due to an increase in the yield per unit area, as well as productive tillering decisive influence on the degree of uniform ripening and grain quality.
