Abstract: The membrane permeability and level of metabolic energy in both cold-tolerant cultivars and cold-sensitive ones of wheat were studied. The results indicated that the osmotic ground values, the membrane permeability constants for water and the membrane permeability constants for urea and urea homologue in the subepidermal cells of leaf sheath in cold-tolerant cultivars were larger than that in cold-sensitives ones,ATPase activity in chloroplast, mitochondria and cytosol in cold-sensitive cultivars was greater than that in cold-tolerant ones, and the decline rate of ATP content in tissues of cold-sensitive cultivars was rapidder than that of cold-tolerant ones after freezing treatment.Membrane perme ability, cell sap concentration and adjustment of metabolic energy play an important role in cold-tolerance for wheat.

Key words: Wheat, Cold-tolerance, Membrane prpermeability, ATP content, ATPase activity
