Abstract
The study is aimed at determining the impact of presowing seed treatment with polyfunctional preparations on the resistance of winter wheat to adverse environmental factors. The work was carried out in 2019–2022 in a zone of unstable moisture in the Stavropol krai. In the experiment the following were studied: winter wheat varieties (factor A), Stavka, Victoria 11; seed treatment with polyfunctional preparations (factor B), without treatment (control), Alfastim (0.05 L/t), Ikar Fosto Seeds (0.5 L/t), Sprintalga (0.5 L/t), Biodux (0.003 L/t). Presowing treatment of winter wheat seeds, on average over the years of research, ensured the formation of a yield of 0.32–0.43 t/ha higher than in the control. The maximum increase in grain yield in the experiment was 0.40 t/ha (Stavka) and 0.43 t/ha (Victoria 11). The proportion of shoots that survived after freezing in the freezer for the Stavka variety was 84.0% on average for the experiment, for the Victoria 11 variety it was 80.8%. The use of polyfunctional preparations Alfastim and Ikar Fosto Seeds reduced the percentage of dead shoots to 13.1 and 8.7%, respectively. Seed treatment with Sprintalga and Biodux worsened frost resistance, there were more dead shoots than in the control, by 10.1 and 8%. In the low-growing Victoria 11 variety, the highest frost resistance was observed when using Alfastim, the number of dead shoots decreased by 13.8% compared to the control (more than two times). Thanks to the presowing treatment of seeds, the resistance of winter wheat to soil salinity increased. For the Stavka variety, when using Ikar Fosto Seeds, the maximum increase in root biomass by 33.3% in 0.5% NaCl saline solution was observed, relative to the control. Treatment of seeds of Victoria 11 variety with Alfastim increased the total length of seedlings in a 0.5% saline solution by 5.6%, in 1.0% by 6.4%. The use of polyfunctional preparations contributed to an increase in the drought resistance of winter wheat during the initial stages of development. When seeds of both varieties were germinated in a 3% sucrose solution, Alfastim increased the intensity of growth of primary roots of the Stavka variety, in comparison with the control, by 22.2%, Victoria 11 by 9.1%, and Biodux by 56.0% and 9.1%, respectively.
