The radioprotective properties of potassium humate were studied under model conditions. The growth dynamics of wheat seedlings treated with 0.01%, 0.001% and 0.001% solutions of potassium humate both before and after γ-irradiation at a dose of 200 Gy was studied. A positive effect of potassium humate solutions on the activity of catalase, the amount of malondialdehyde, chlorophyll pigments and carotenoids, fluorescent characteristics (the maximum quantum yield of PSII (photosystem II) in seedlings obtained from gamma-irradiated wheat seeds was revealed.

Key words: wheat seedling, γ-irradiation, lipid peroxidation, potassium humate, malondialdehyde, seed germination
