In this paper were investigated features of accumulation and changes in the content of anthocyanins, flavonoids and carotenoids in different organs Alhagi pseudalhagi (Bieb.), grown in conditions of chronic γ-radiation. An attempt was made to clarify the role of these nonenzymic antioxidants in conditions of radiation stress. On the basis of a slight increase in pigment content was concluded that the protective responses in the plant are involved nonenzymic antioxidants less effective.
