Effect of solutions based on modified bentonite, for the first stages of development of spring wheat

In modern crop production, the development of methods for pre-sowing seed treatment is of particular relevance. One promising area is the use of modified bentonites as growth promoters and protective agents. This study was conducted on spring wheat seeds that were treated for 5 minutes in 0.5% aqueous suspensions of the activated natural mineral bentonite modified with various amino acids and humates. Untreated seeds served as controls. Analysis of the obtained data showed a significant effect of modified bentonite on the indicators of germination energy and seed germination. Values of germination energy of treated seeds exceeded control ones by 10-21.9%. Morphometric studies revealed a significant increase in the length of seedlings treated with Na-clay with glycine and lysine, and their stimulating effect on the growth of the main root. The best results on the development of the root system were demonstrated by samples treated with Na-clay with asparagine (4.3-4.6 roots). The highest concentration of antioxidants was observed in the pure Na-clay system (208.3 mg/100 g).
