Abstract

Proline content in leaves of the mutant increased more significantly than that of the wild type when exposed to NaCl stress. The content of proline increased for 72 h and then decreased in both types, but was higher in the mutant than in the wild type. When exposed to NaCl stress of 200 or 300 mmol/L for 96 h, the content of soluble sugars in leaves of the mutant maintained a higher level than that of the group without NaCl treatment, but that in the wild type became much lower than that of its control group.
