In plants which are exposed to salinity , There is a specific relationship between composition of cellular inorganic ion contents and proline and soluble sugars accumulation Two wheat cultivar seedlings were treated with 0,50,100, 175 mM sodium chloride in Hogland nutrient solution and accumulation of the compounds were studied. proline and solbule sugars accumulated and growth reduced significantly at 175 mM. The study of 10 wheat cultivars at this treatment showed that the relative growth rate had a positive and significant correlation (<0.01)with root and shoot potassium content and had negative and significant correlation (<0.01) with root and shoot sodium, leaf proline , shoot soluble sugars and shoot monovalent cations contents. The results indicated that there is not the positive and significant correlation between proline and soluble sugars accumulation and wheat relative salt tolerance.
