The salt stress decreased the parameters of plant growth such as dry weight, aerial parts and roots length, total chlorophyll, carotenoids and potassium content. But, treatment of plant with SA under salt stress increased the above–mentioned parameters. At the same time, peroxidation of membrane lipids, percentage of membrane leakage, the amount of hydrogen peroxide and sodium content of the plant were increased under salt stress. On the contrary, the presence of exogenous SA decreased the above parameters. The obtained results indicated the modulator effects of salicylic acid on physiological processes of the Artemisia aucheri Boiss. under salt stress.
