MITIGATING ALUMINUM TOXICITY IN SEEDLINGS OF GLYCYRRHIZA GLABRA L. USING SILICON
Abstract
Background: Silicon is a beneficial element for the plant, with the primary role in increasing plant resistance to heavy metals toxicity and considering the importance of phytoremediation to remove heavy metals from contaminated soils. It could be used for the exogenous application for alleviating the harmful effects of heavy metals on the plant. Aim: This study aimed to investigate the role of Silicon in balancing the destructive effects of aluminum on Glycyrrhiza glabra L. Methods: the seedlings were grown under a hydroponic system using Long Ashton nutrient solution; the 15-day-old seedlings were exposed to Silicon (0, 0.5, 1.5 mM) for 110 days and afterward stressed by interactions of aluminum chloride (AlCl3.6H2O; 0, 100, 250, and 400 M). Result and Discussion: the interactive effects of Silicon significantly ameliorated the negative consequences of aluminum toxicity. The combination of Si 1.5 mM and Al 400 μM produced the highest biomass in shoots (45.67 g). The
