Abstract
The author(s) studied the influence of various growth regulators on the yield and grain quality of the spring wheat variety “Zemlyachka” under the conditions of the forest-steppe of the Volga region. The studies have shown that pre-sowing treatment of seeds with growth regulators has a positive effect on the yield of the experimental crop, providing an increase of 0.17–0.40 t/ha. The use of growth regulators in the technology of cultivation of spring wheat has a positive effect on the formation of grain quality indicators, which determine the technological and baking properties of products, such as the content of protein and starch, the quantity and quality of gluten, and the volumetric weight of grain.
Highlights
The regulation of plant growth and development with the help of physiologically active substances allows one to influence the individual stages of ontogenesis in order to mobilize the genetic potential of the plant organism and, to increase the productive capacity and quality of crops.In recent years, much attention has been paid to the development and application of growth regulators of a new generation with a wide range of physiological activity that are safe for humans and the environment

The use of plant growth regulators has a positive effect on obtaining stable high yields [5,6,7]
Summary
The regulation of plant growth and development with the help of physiologically active substances allows one to influence the individual stages of ontogenesis in order to mobilize the genetic potential of the plant organism and, to increase the productive capacity and quality of crops.In recent years, much attention has been paid to the development and application of growth regulators of a new generation with a wide range of physiological activity that are safe for humans and the environment. The regulation of plant growth and development with the help of physiologically active substances allows one to influence the individual stages of ontogenesis in order to mobilize the genetic potential of the plant organism and, to increase the productive capacity and quality of crops. The study of the influence of growth regulators of the new generation on the yield and quality of grain of spring wheat taking account of the specific soil and climatic conditions is important [1,2,3,4]. In connection with the previously mentioned, the purpose of our research was to study the effect of growth regulators on the productive capacity of spring wheat of the variety “Zemlyachka” under the conditions of the forest-steppe of the Volga region. Heavy metals (Hg, Pb, Cu, Zn, Cd, Ni) in the grain were determined by plasma and electrothermal variants of atomic absorption spectroscopy with preliminary preparation of samples by the method of “dry” mineralization in the agrochemical laboratory of Ulyanovsk (State Standard 8.505.-84; MI -858.-85)
