Description of the subject: Soil salinity is a severe obstacle to seed germination and early seedling growth; any boost treatment that improves salt resistance during these critical developmental stages will be of major interest. Objective This study precise the influence of salicylic acid (SA) on seed germination in presence of MgCl2 (SS). Methods : A hydroponic experiment was conducted to analyze germination percentage , germination kinetics, length and fresh weight of seedling (hypocotyls and coleoptiles) in two varieties of tomato seedlings Saint-Pierre and Semillas de Alta Seleccion grown under six treatments, including control, 50mM and 100mM of (MgCl2), and (50mM MgCl2 + 0.25mM SA), (50Mm MgCl2 +0.50Mm SA) , (100mM MgCl2 + 0.25SA) ,(100mM MgCl2 +0.50mM SA). Results: The results proved that the application of salicylic acid (SA) increased germination under salt stress conditions, and the physiological processes for salt tolerance were studied in this research. The effect of SA on salt tolerance during germination revealed that the SA application (SA + MgCl2) significantly increased the reduced rates of germination and growth (in terms of hypocotyls and coleoptiles lengths) caused by salt stress. The application of SA to both high and low saline soils improved growth. SA increased the germination percentage of seeds and increased seedling length in both cultivars. Increasing the dose of SA had just a slight effect on most parameters; in contrast, the irrigation with 0.25mM of SA in the presence of MgCl2 significantly improved germination and fresh weight of seedlings in connection to more efficient management of oxidative stress in both cultivars. Conclusion: The study found that using SA to regulate physiological mechanisms in tomatoes could help to minimize the negative impact of salt stress. To conclude, SA can be used as a booster agent for improvement of salinity resistance at the germination stage.
