Title: Effects of salt stress on MDA,protective enzyme system,proline and soluble sugar of Sedum aizoon seedling
Abstract: The salt-tolerant mechanism of Sedum aizoon seedling under different concentrations of NaCl solution(50,100,200,400 mmol/L)was studied by measuring the fresh weight,SOD,POD,CAT,MDA,Pro,soluble sugar after treating for 0,3,7,15 and 30 days.The average daily growth amount of fresh weight was increased 4.8% under 50 mmol/L,and no significant change was found under 100 mmol/L,it was decreased 9.2% under 200 mmol/L and died under 400 mmol/L.The contents of MDA,SOD,POD,CAT,Pro and soluble sugar were increased along with the salt concentration.And all the physiological indexes stabilized after 30 days treatment.The maximum salt concentration which Sedum aizoon seedling could stand was 200 mmol/L.
