The changes of main metabolites in three cultivars of Triticumaestivum L. under the effects of lead and osmotic stresses were investigated. The results indicated that, the amount of soluble sugars in different plant organs were increased under low Ψs and in the presence of Pb element. Also, the decreased Ψs and Pb concentration led to an increase in the free amino acids of roots. The content of soluble proteins was variable among the cultivars. Apparently, the soluble proteins were increased in response to low Ψs and Pb, except in roots of cv.Giza168which were increased under high Pb concentrations. Statically, the Ψs had the predominant role on the soluble sugars, free amino acids and total soluble proteins in all investigated plants. The significant correlations among the main metabolites were positive under the effect of lead, Ψs and their interaction with few exceptions.
