The work is devoted to the issues of assessing the degree of stimulating effect of silver nanoparticles (AgNPs) on cress seeds and seedlings. As part of the study, a solution of silver nanoparticles obtained in a polyvinyl alcohol matrix was used for stimulation, ascorbic acid was used as a reducing agent, which makes it possible to classify the synthesized solutions as "green nanotechnologies". The use of silver nanoparticles in agriculture can improve the immunity of plants. This effect is due to bactericidal, bacteriostatic, fungicidal and antiviral properties of silver nanoparticles. In addition, silver nanoparticles are exogenous elicitors; therefore, they have a growth-stimulating effect. The results of the study show that the applied solutions of silver nanoparticles increase the energy of germination and seed germination, increase the biomass of dry matter, and the concentration of vitamin C in the ground part of cress. The greatest degree of accumulation of silver in the case of cress is observed in the roots. In this case, the excess of the permissible concentration of silver is not observed.
