Abstract

Stress protectors (adaptogens) are among the most important factors that regulate growth processes at all stages of plant development. This article presents results of field studies of the effect of new synthetic plant growth regulators of stress protectors (adaptogens) on the elements of productivity and yield of spring oats of the Skakun variety. The obtained results during the research showed that all the studied derivatives of peredazinones are adaptogens and they contribute to an increased productivity and increased yield of spring oats. We studied the effect of pre-sowing treatment of seeds with new synthetic plant growth regulators of stress protectors on the quality indicators of cereal production of Skakun oats (protein, starch and amylolytic enzymes content in the cereal). Pre-sowing treatment of oat seeds increases the amount of protein in the cereal up to 15%, starch – up to 25%, amylase – up to 20%. We proved the ability of stress protectors to minimize the negative impact of heavy metals (lead, zinc) on agrophytocenoses, which will make it possible to obtain environmentally friendly cereal products when cultivating oats in anthropogenically polluted areas of the Saratov Oblast.

Highlights

  • Oats is a significant food and feed crop in the Russian Federation

  • After treating oat seeds with combinations of synthetic plant growth regulators (SPGR) + Pb+2 and SPGR + Zn+2, the negative effects of the lead cations (Pb+2) and zinc (Zn+2) were neutralized in all of the studied concentrations, which contributes to an increase in seed germination by 5.0-14.3%

  • We studied the effect of pre-sowing treatment of oat seeds with solutions of SPGR, lead cations (Pb+2), zinc (Zn+2) and their combinations (SPGR + Pb+2 and SPGR + Zn+2) on the number of grains in a panicle, grain weight with panicles, weight of 1000 grains, the number of spikelets in a panicle, the height of plants

Summary

Introduction

Oats is a significant food and feed crop in the Russian Federation. Oat productivity is significantly reduced due to environmental pollution. The issue of obtaining a high stable grain crop that meets the environmental safety criteria arises at the present. At the present stage of the agricultural technologies’ development, application of synthetic plant growth regulators is an environmentally safe and cost-effective way to increase crop yields. Usage of synthetic plant growth regulators for pre-sowing treatment of seeds even in small doses leads to significant changes in morphological and physiological processes in plants.
