Salt stress is a major constraint to crop productivity, negatively affecting plant physiology and fruit quality. This study hypothesized that seed priming with polyethylene glycol (PEG6000) might enhance antioxidant activity by mitigating oxidative in Solanum lycopersicum ‘Micro-Tom’ under salt stress. Seeds primed –1.2 MPa PEG6000 were grown Rockwool treated 0, 50, 100, 150, 200 mM NaCl. Primed plants showed 32% increase leaf potassium (K+) 28% decrease sodium (Na+) accumulation compared non-primed 150 Glucose, fructose, sucrose contents increased 25%, 22%, 19%, respectively, fruits, while citric acid decreased 15%. Malondialdehyde (MDA) electrolyte leakage reduced 35% 29%, moderate salinity. Antioxidant enzyme activities—SOD, POD, CAT, APX enhanced 30–45% 100 NaCl, controls. Abscisic (ABA) levels 40% roots Activities of polyamine-related enzymes (DAO, PAO, ADC) also rose significantly. Priming improved protein content 20% relative water 18%. These results suggest enhances tolerance boosting defense, regulating osmotic balance, improving ion homeostasis, offering viable strategy for sustaining tomato productivity
