Abstract
Mitigative effects of exogenous calcium on the plant growth and leaf anti-oxidative enzyme activities of Brassica napus seedlings under seawater stress were investigated with liquid culture method. The results showed that growth states of Brassica napus were significantly inhibited in 30% seawater culture. Optimum concentration of CaCl2 could effectively relieve the seawater damage to Brassica napus, resulting in elevated germination rate, seedling height, fresh weight and chlorophyll content; while SOD and POD maintained high activities. The results from this study showed that the proper concentration range for the growth of Brassica napus were from 10 to 20 mmol·L-1, and excessively high CaCl2 concentration had inhibition on seedling growth.
