Salinity-Induced Alterations in Cations Uptake And Their Mitigation By Exogenous Treatments In Wheat Seedlings

Salinity poses a danger to the production of wheat (Triticum aestivum L.), by impacting plant growth and productivity. Deficits in vital minerals like potassium (K⁺) and calcium (Ca²⁺) result from the buildup of sodium (Na⁺) and chloride (Cl⁻) ions in salty soils, which impairs nutrient absorption. To mitigate salinity-induced decrease in mineral content in wheat seedlings, this study examines the ameliorative effects of growth regulators, specifically gibberellins (GA) and cytokinins, in combination with potassium (K⁺) and calcium (Ca²⁺) supplementation. It was discovered that cytokinins and gibberellins improved mineral uptake under salt stress by promoting stress tolerance, nutrient translocation, and root development. Furthermore, the application of exogenous potassium and calcium led to the restoration of ionic balance, a decrease in Na⁺ toxicity, and an overall increase in seedling vigor. Seed priming with plant growth regulators and minerals helped to improve the level of nutrients in wheat seedlings under saline conditions
