In this work, the influence of proline and ascorbic acid on physiological parameters in seeds subjected to different levels of salt stress was studied in tomato. The salinity stress declined seed germination and seed vigour parameters. Different treatments (hydration, different concentrations of proline 5mM, 10mM and ascorbic acid 1mM, 4mM) were given to seeds at 25mM, 50mM and 75mM NaCl concentrations. Seed germination was declined with the increasing level of salt stress. All the seed treatments increased the physiological parameters (percent germination, seedling length, seedling biomass, speed of germination, vigour index I and II) of seedlings as compared to control at different salinity levels. The results showed that proline 10mM and ascorbic acid 4mM were more effective than proline 5mM and ascorbic acid 1mM respectively.
