The presence of metals in the leaves can hamper plant metabolism and growth even at very low concentrations. However, treatments without the application of citric acid and fertilizer resulted in a higher TF value (13.9). In this review, the effective role of glycine betaine (GB) in alleviation of HM stress is summarized. The unfavorable effects of the above mentioned stresses are increased mainly by climate change because of unseasonal weather conditions (Fedoroff et al. The doses of 0, 5, 10, 20, and 40 ppm were used. However, when TMs reach the protoplast, activation of antioxidant machinery may significantly strengthen the status of plants naturally growing in TM-polluted environment.
