For the first time, the effect of pre-sowing treatment of seeds with different doses of γ-rays on the development of maize was studied under salt stress. The response of the plant to such conditions was evaluated based on changes in the amount of antioxidants such as anthocyanins, carotenoids, and flavonoids. The treatment of seeds with γ-rays in the dose range of 1-5 Gy was found to stimulate the growth of plants exposed to salt stress. In this case, carotenoids play a key role in protecting the plant from salt stress. An increase in the concentration of salt leads to a significant increase in the amount of yellow pigments. In this process, along with carotenoids, anthocyanins also play a certain role.
