The article presents the results of laboratory studies to assess the effect of a colloidal solution of silver nanoparticles on the sowing quality of wheat seeds of the Novosibirskaya 15 strain recommended for cultivation in the Krasnoyarsk Territory and an assessment of its influence on its seed productivity. It was found that the use of a colloidal solution of silver nanoparticles in the processing of seed material of the Novosibirskaya 15 soft spring wheat strain significantly increases the rate of seed growth, raising it from 63% in the control to 87% in the variant with a 50% solution of silver nanoparticles. It was found that the colloidal solution of silver nanoparticles did not affect on the indicators of seed germination and their germination energy.
