Salt stress interrupts physiological and biochemical behaviors of plants by lowering the osmotic potential. The seed priming is an important technique which enhance the growth and yield by reducing the salt stress. The recent study was conducted to improve the salt tolerance in wheat plants. The seeds of wheat were primed with two concentrations (100ppm & 200ppm) of ZnSO4 and CuSO4 and then seed were grown under NaCl stress in both experiments i.e.; Invitro and Pot experiment. The results showed that seed priming with both ZnSO4 and CuSO4 increased the growth of wheat plants more than control under salt stress. The antioxidant enzymes (CAT. POD, SOD) are increased under salt stress. The seed priming with ZnSO4 improved the growth and antioxidant enzymes activities more than CuSO4 under all levels of salt stress.
