Abstract:
Taking eleven imported wine grapes as materials，the salt tolerance of different grapes was tested，four varieties with relatively stronger salt tolerance were screened according to salt injury index，shoot high as well as root numbers under different salt concentration.The proline and malondialdehyde (MDA) contents as well as superoxide dismutase (SOD) and peroxidase dismutase (POD) activities of three grapes with different salt tolerance were examined.The results showed that the MDA content of three varieties all increased，but that of ‘Dechaunac’ with weak salt tolerance increased more significantly.SOD and POD activity of ‘Vidal Blanc’ and‘Villard Blanc’ with high salt tolerance keep increasing under different salt concentration，that of ‘Dechaunac’ increased under 0.20% NaCl whereas decreased under 0.40%NaCl，this result indicated that ‘Villard Blanc’and‘Vidal Blanc’keeping high antioxidant enzyme activity was an important way for wine grape to resist oxidation induced by salt stress.The proline content of three varieties increased at different level under salt stress，but there was not positive correlation between proline content and salt tolerance.
