Abstract
The effect of growth regulators on physiological processes in cucumber seedlings at the initial stages of ontogenesis was studied. Seeds were analyzed by treatment with 2,6-dimethyl-(4-dimethylaminophenyl)-4n-selenopyran, diacetophenonyl selenide, sodium selenite, selenium nanoparticles, and water; a control experiment was also carried out with a water-alcohol solution. It was found that diacetophenonyl selenide had the greatest stimulating effect on stress resistance of seeds, the accumulation of seedling biomass was 8.7–17.7% more than in the control. The results showed that the increase in root dry matter accumulation was significantly higher than the other samples measured. Under conditions of salt stress, the treatment of wheat seeds with selenium nanoparticles reduced the inhibition of the growth characteristics of seedlings compared to the control variant. The tendency to increase the stimulation of the root biomass with selenium in comparison with other variants remained. In the experiment of treating cucumber seeds with a selenium nanocomposition, it was found that salinization had a more negative effect on the germination of seeds grown under conditions of chloride salinity, 1.6–1.9 times less than in the control experiment (distilled water). At the same time, inhibition of the growth of root biomass was noted by 20%. The roots are constantly in contact with saline soil, so high salt concentrations inhibit the growth of roots more than above-ground organs. Such an environmental factor as salinity reduces the ability of plants to absorb water.
