摘要
Abstract
Using different concentrations of PEG-6000 simulated drought conditions, the changes of relative water content, praline content, soluble sugar content, MDA content and superoxide dismutase (SOD) activity in leaves on the bare fruit seedling. The result shows that the relative water content of the bare fruit seedling leaves decreased significantly, the proline content increased, the proline accumulation significant when concentration of PEG-6000 is 10% and 15%, soluble sugar content decreased significantly, the content of MDA increased significantly, the drought caused significant damage to membrane system at PEG-6000 stress concentration increases, but the leaf can through enhanced superoxide dismutase (SOD) activity to produce antioxidant protection, relieve oxidative damage . That is, the drought stress caused significant damage to the bare fruit seedlings, and the seedlings also showed a certain drought adaptability.关键词
