Abstract:
Using two salinity-resistance grape variants:‘Summer black’(weak salt resistance) and ‘Rizamat’(strong salt resistance) as the materials,the soluble protein content,the proline content,MDA content,the relative electric conductivity and the level of three enzymes’activity(CAT,POD,SOD) after treating the leaf surface with ALA at the concentration of 0,75,150 mg/L,which respectively corresponds to three salinity-stress levels of 0,2,4 g/kg were studied.The results showed that as for the ‘Summer black’(75 mg/L ALA,2 g/kg salinity stress) and the ‘Rizamat’(150 mg/L ALA,4 g/kg salinity stress) respectively,the soluble protein,proline content and the level of the three different enzymes’activity increased significantly,however the MDA content,relative electric conductivity decreased significantly.
