The results of the study of the effect of chitosan solutions with a concentration of 0.005 to 0.2% on the morphophysiological and biometric parameters of plant seedlings are presented: wheat Triticum aestivum L. cv. Saratovskaya 29, sorghum sorghum cv. Volzhskoe, cucumbers Cucomerario cv. Golubchik, beans G, Phaséolus of the Franco-wagon variety, Písum peas of the Alpha variety.
The stimulating effect of chitosan on the seedlings of the main agricultural crops has been established. The concentration dependence of the positive effect of treatment and watering of plants with chitosan solutions on biometric and morphophysiological parameters was revealed. An increase in germination and acceleration of the growth of cereal plants under laboratory conditions is achieved when treated with chitosan at concentrations: 0.01% for sorghum of the Volzhskoe variety, and 0.02% for wheat of the Saratovskaya-29 variety. For beans, a positive effect was achieved when treated with chitosan at concentrations: 0.005; 0.01; 0.02; 0.03; 0.05; 0.09; 0.2; 0.5% for vital indicators, germination and increase in the mass of beans of the Franco-wagon variety. The positive effect of chitosan on the vital characteristics of cucumber variety Golubchik was achieved at concentrations, %: 0.01; 0.05; 0.09 and 0.02 and 0.2% for the germination of Alfa peas.
