Undoubtedly, salinity is the major environmental stress affecting the crops growth, development and yield. Grapevine is a dominant horticulture crop and mildly sensitive to the salinity. Salinity triggers variations at the cellular and molecular levels and hence induces some specific genes expression. The responses of two grapevine cultivars (Fakhri and Sultanin) were evaluated for its tolerance to the salinity stress in vitro. The results for the explants exposed to the salinity revealed that the viability, fresh weight of the regenerated explant and the proliferation rate were declined compared to the control ones. The activity of SOD enzyme and MDA content were increased with salinity. However, protein content declined. There was no significant difference in CAT and APX activities with the salinity treatment. With salinity adding up, the DREB/CBFs genes expression pattern was significantly increased in both cultivars. ‘Fakhri’ was more responsive in growth parameters and the activity of antioxidant enzymes and higher expression rate of DREB/CBFs under salinity compared to the variety ‘Sultanin’.
