Thiourea and arginine synergistically preserve redox homeostasis and ionic balance for alleviating salinity stress in wheat.

ABSTRACT: Plant growth regulators are cost-effective and efficient methods for enhancing plant defenses under stress conditions. This study investigates the ability of two plant growth-regulating substances, thiourea (TU) and arginine (Arg), to mitigate salinity stress in wheat. The results show that both TU and Arg, particularly when used together, modify plant growth under salinity stress. Their application significantly increases the activities of antioxidant enzymes while decreasing the levels of reactive oxygen species (ROS), malondialdehyde (MDA), and relative electrolyte leakage (REL) in wheat seedlings. Additionally, these treatments significantly reduce the concentrations of Na⁺ and Ca²⁺ and the Na⁺/K⁺ ratio, while significantly increasing K⁺
