Abstract
The effect of calcium at different concentrations (0, 5, 10, 15 mmol·L-1 and 20 mmol·L-1) on physiological characteristics of maize seedling leaves under chilling stress was studied. The results showed that compared with the CK, the growth of maize seedling were inhibited and the accumulation of soluble protein and soluble sugar content were maintained , the antioxidant enzymes activities and proline content were reduced, whereas MDA content and membrane permeability were increased under chilling stress. The Ca2+ treatment with the concentration ranging from 5 to 10 mmol·L-1 showed mitigating effect of maintaining membrane permeability and the activities of SOD, POD and CAT, and promoting the accumulation of proline, soluble sugar and soluble protein content in maize seedling. In addition, concentration of 10 mol·L-1 Ca2+ showed the largest positive influence on seedling growth.
