Seed priming can significantly enhance the tolerance of soybean against different environmental stresses by improving seed water uptake and modulating stress-response mechanisms. In particular, with sodium carboxymethylcellulose (SCMC) gum Arabic (GA) support seeds to withstand extreme conditions better, promoting more consistent germination robust seedling establishment, which is crucial for achieving stable agricultural yields. The present study investigated effects using a combination SCMC GA (10% CG) on germination, growth, biochemical responses six varieties under drought flooding stress conditions. results revealed significant differences among applied treatments vigor, physiological traits. Under stress, 10% CG improved percentage, rate, shoot length, root biomass compared unprimed seeds. Notable reductions in malondialdehyde (MDA) content enhanced antioxidant enzyme activities, including superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), suggest that mitigates oxidative damage through defense Moreover, growth parameters but advantages were less significant. addition, treatment reduced electrolyte conductivity (EC) across all seeds, indicating membrane stability. Overall, was effective conditions, demonstrating potential strategy enhancing varieties.
