Effect of plants treatment by salicylic acid on the water potential, ethylene emission, intensity of lipid peroxidation oxidation and enzymatic antioxidative activity in the leaves with contrasting drought-resistance of winter wheat cultivars was investigated. It is ascertain, that the treatment of plants by salicylic acid contributes to a decrease of water loss and intensity of lipid peroxidation, to an increase of ethylene synthesis and peroxidase, catalase, superoxide dismutase activity in the winter wheat leaves under drought conditions.

Key words: Triticum aestivum L., water potential, drought, ethylene, peroxidase, catalase, superoxide dismutase, lipid peroxidation, salicylic acid.
