Summary

The experiment on mung bean (Vigna radiata) in 2023 commenced at the laboratory of the University of Kerbala, Kerbala, Iraq. It aimed to determine the role of trehalose and glutathione in reducing cadmium (Cd) toxicity. The mung bean cuttings served as an experimental material to evaluate the best method of applying trehalose and glutathione in reducing Cd toxicity. Root response, antioxidant defense, and peroxidation were the indicators used. With pre- and post-treatment of trehalose and glutathione and in combination with Cd, significant differences occurred for these treatments. By treating with Cd, trehalose and glutathione were able to remove Cd toxicity and showed an increase in rooting response. By using trehalose and glutathione together in mung bean, and using Cd during the first 24 hours, their effect was inhibitory. However, when treated together with the toxic Cd, the trehalose and glutathione removed the Cd toxicity in mung bean, improved the rooting response, and raised the levels of GSH, ASA, and CAT, and SOD activity. In addition, they decreased the level of MDA and the lipoxygenase activity compared with the control treatment. The study concluded that the combination of trehalose and glutathione showed a promising protection for mung bean plants from Cd toxicity.

Mung bean (Vigna radiata L.), rooting response, antioxidant, glutathione, trehalose, cadmium toxicity.

The combined effects of trehalose and glutathione before and after Cd application during the first 24 hours resulted in inhibitory action in mung bean (Vigna radiata L.). However, when applied in combination with the toxic Cd, the Cd toxicity vanished, with the rooting system enhanced along with the levels of GSH, ASA, CAT, and SOD.
