Role of growth regulators with anti-stress properties in overwintering and productivity of winter wheat

Abstract

The paper states that study of the production process of winter wheat plants, including overwintering of plants. It showed that the plants treatment with biological products Albit and Moddus in the phase of 3-5 leaves had a positive effect on the studied parameters. The treatment with Albit increased the number of shoots and plant height, while Moddus increased the mass of plants and roots, the number of secondary roots and leaves, and the content of sugars and monosaccharides. The treatment with Moddus helped to preserve some overwintered plants by 6%, and Albit by 5% in comparison to untreated ones. The loss of sugars was insignificant, up to 5% for untreated plants, up to 4.6% when treated with Albit, and up to 3.8% when treated with Moddus. The sugar content in the tillering nodes was 16.2%, when treated with Albit was more by 10%. The sugar content in the tillering nodes was 16.2%, when treated with Moddus was by 21%, i.e., with an even more significant volume. The fully ripe grain had a high content of sugars and starch. The treatment with Albit promoted an increase in starch up to 16%, and with Moddus, an increase in sugars by 26%. The mass of a thousand grains and grain yield increased when treated with Albit and Moddus. The mass of 1000 seeds was equal to 2.5 g, the yield when treated with Albit by 16%, and it increased with Moddus by 20%.
