Abstract

The effects of soaking seedlings of four abscisic acid (ABA) concentrations (0, 1, 5, 10, and 20 μmol/L) on physiology and ecology of pea under cadmium stress were studied by the pot experiment. The results showed that the soaking treatment with ABA improved the morphological indexes of pea plants. The contents of chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids of pea seedlings were increased compared with the control, and reached a maximum at ABA concentration of 5 μmol/L. Compared with the control, the POD, SOD, CAT activities and soluble protein content of pea seedlings were significantly increased, and the concentration of ABA at 5 μmol/L was the best. Therefore, soaking seeds with ABA could improve the physiological and ecological effects of pea seedlings under Cd stress.
