Various abiotic stresses may affect the germination, growth, and yield of direct-seeded vegetable crops. Seed priming with effective antioxidant mediators alleviate these environmental by maintaining uniformity in seed germination improving subsequent health developing seedlings. Salt-induced stress has become a limiting factor for successful cultivation Brassica rapa L., especially Southeast Asian countries. The present study was performed to elucidate efficacy using selenium (Se) mitigating salt-induced oxidative turnip crops reducing uptake Na+. In this study, we administered three different levels Se (Se-1, 75 μmol L-1; Se-2, 100 Se-3, 125 L-1) alone or combination NaCl (200 mM). Conspicuously, salinity Se-2 modulated expression genes, including catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), ascorbate (APX). upregulated stress-responsive genes alleviated salt scavenging higher reactive oxygen species (ROS) level. ameliorative potential (Se-2 = enhanced final percentage, photosynthetic content, seedling biomass production up 48%, 56%, 51%, respectively, under stress. advantageous effects were attributed alleviation through reduction malondialdehyde (MDA), proline, H2O2.
