Background: Salinity is a significant abiotic stress which affects eggplant (Solanum melongena) growth and development, decreasing photosynthesis and reducing yield. To address this problem, we performed a salt induction response (SIR) study in eggplant. Methods: In this experiment, we optimized the salt induction cycle of 60, 80, 100 and 125 mM NaCl concentrations at 120-min time intervals. Eggplant seeds were exposed to three treatments. In particular, induced, non-induced, and control. The induction responses were tested with a supply of sub-lethal dose (100 mM NaCl) of saline water irrigation. Results: Salt induction improved the eggplant seedling vigour, germination, adjusts the physiology, antioxidant machinery and increase the fruit yield under salinity. Conclusion: Salt induction acclimatizes the eggplant seedlings to salinity stress and enhances the salinity tolerance at the whole-plant level.
