Abstract

The research was conducted in 2024 in a laboratory experiment at the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy (Moscow). The use of a complex of short peptides made it possible to influence the intensity of seed germination, having a positive effect on the morphometric parameters of spring wheat seedlings: the weight of 100 pieces of roots increased when treated with KE dipeptide by 48...245% (by 1.7…4.9 g) compared with the control; when treated with AEDG tetrapeptide by 6…47% (by 3.6..7.3 g). At the same time, a significant increase in root length was noted by 17% (by 1.3 cm) when treated with KE dipeptide at a concentration of 1*10-9 g/l; by 16% (by 1.2 cm) when treated with AEDG tetrapeptide at a concentration of 1*10-12 g/l. The height of the sprout increased with a decrease in the concentration of dipeptide KE by 16..26% (by 1.5..2.4 cm); with the use of tetrapeptide AEDG by 33…35% (by 3.3..2.4 cm). The weight of the sprouts (100 pieces) of the grain increased by 27% (by 1.4..1.6 g) compared with the control (dipeptide KE).
