  • Descrição: Lead is known as the second toxic heavy metal which negatively affects plant growth. Hence, there is a need to develop eco-friendly techniques to overcome the negative impacts of Pb on plants. Plant hormones play an essential role in amelioration of heavy metal toxicity. In the current study, the effects of exogenous application of methyl jasmonate (0, 10, 30 and 50 µM) on growth, antioxidant enzymes and Pb uptake of two contrasting cultivars of cluster bean (RGC 1055 and RGC 1066) were evaluated under various lead-treatments (0, 600, 800 mg/kg). In RGC 1066, the Pb uptake in roots, shoot, leaves, and pods decreased by 49.28%, 43.73%, 32.78% and 29.06%, respectively by the exogenous application of MeJA (10µM) under Pb stress (800 mg/kg). The current findings concluded that MeJA enhanced the detrimental effect of lead by increasing growth, activity of antioxidant enzymes and reducing Pb accumulation in both cultivars. Hence, application of MeJA can be considered as an efficient method in minimizing toxic effects of lead by reducing lead uptake in cluster bean cultivars growing in contaminated soil.
