Effects of salicylic acid on physiological characteristics of strawberry leaves under drought stress.

摘要

The effects of the salicylic acid (SA) on the content of soluble carbohydrates, free proline, malonaldehyde(MDA) and the activity of superoxide dismutase (SOD),peroxidase (POD), catalase (CAT) in strawberry seedling leaves under drought stress were studied. The results showed that under drought stress, suitable concentration of SA increased the content of osmotic adjustment substances such as soluble carbohydrates and free proline of strawberry leaves. Meanwhile, it induced the activity of antioxidant enzymes, alleviated membrane lipid peroxidation as well as membrane system damage, thus improving the drought resistance of strawberry plants.
