Abstract: “This study was designed to examin the effect of exogenous application of β-carotene and algal extract to mitigate the deleterious effect of salt stress in wheat plants. Generally, salt stress induced changes in the contents of compatible osmolytes and some antioxidants compounds in the different plant parts of T. aestivum. The results indicated that applying of β-carotene or algal extract can used to ameliorate the deleterious effect of salt stress and could be enhance the level of free amino acids, proline, glycine betaine, choline, glutathione, ascorbic acid, phenolic contents and total antioxidants activity in both shoot and grains.”
