The response of common vetch seedlings to salt and available water level tolerance were compared for water holding capacity (WHC) and the dry matter of shoots, roots as well as shoot weights after 2 h incubation at 30 deg C and 1 h incubation at 105 deg C. Various levels of salinity and available water were tested. Germination was not affected by the salinity and available water. On the contrary, 1.35 dS/m salinity increased the fresh weights of the shoot (1.179 g) and root (0.580 g), weights after 2 h incubation at 30 deg C (shoot: 0.0456, root: 0.0325 g) and 1 h incubation at 105 deg C (shoot: 0.0104 g, root: 0.0073 g), WHC (0.0123 g) and dry matter (0.0236 g) of the shoot in seedlings. The highest fresh weight (root: 0.567 g, shoot: 1.113 g) and WHC (0.0112 g) were determined when the available water level equaled to the field WHC.
