Abstract
The glass lettuce was made as material, the effect of different concentrations (0, 1, 5, 10, 20 μmol-L−1) of exogenous abscisic acid on growth, antioxidase activity and osmotica of lettuce seedlings under salt stress was studied. The results showed that the root length, stem diameter, and dry fresh weight of lettuce sprayed with abscisic acid were higher than those of the control. Within a certain concentration range, the activities of antioxidant enzymes POD, SOD and CAT increased with the increase of abscisic acid concentration. The soluble protein content increased but the MDA content decreased, which maintained the balance of intracellular reactive oxygen metabolism and prevented membrane lipid peroxidation. Therefore, spraying the exogenous abscisic acid could increase the resistance of lettuce to salt stress, and the best effect was obtained when the concentration was 10μmol·L−1.
