Pre-sowing seed treatment contributes to increasing the productivity of crops. One of the effective physical methods of pre-sowing treatment is the treatment of seeds with ultraviolet radiation, which, depending on the selected range of parameters, can have both a stimulating effect and a bactericidal effect.The article presents the results of a study of the effect of the dose of exposure and the wavelength of ultraviolet radiation of the UV-B and UV-C ranges on the length of sprouts, germination energy and germination of seeds of winter wheat "Zernogradka-9". Regression equations reflecting the relationship between the parameters characterizing the sowing qualities of seeds and the wavelength and dose of exposure to ultraviolet radiation were obtained.Ultraviolet radiation from region B at a wavelength of 313 nm has been found to have a stimulating effect on seeds in the dose range of 24–120 W∙s/m2. Sprout length, germination energy and germination were higher than in the control. Radiation from the UV-C region during seed germination is a deterrent.
