Effect of Seed Soaking with La(NO₃)₃ on Root and Seedling Growth of Adzuki Bean under Different Concentrations NaCl Stresses

Effect of seed soaking with La(NO₃)₃ on the growth of adzuki bean under slat-stresses was carried out,The results showed that:(1)comparing with the control group,the adzuki bean seedling under slat-stresses has small plant height.And the area of leaf,fresh weight of stem and leaf,root activity,SOD and POD and CAT activities decreased drastically.The MDA content increased significantly at the same time.(2)Seed soaking with the La(NO₃)₃ increased the plant height,area of leaf,total root length and number,chlorophyll content ,root activity and the activity of SOD and POD and CAT,and the change range of almost all index under slat-stresses was remarkably higher than that under normal condition.And therefore decreased the detrimental effects resulting from the slat-stresses.(3)Lower concentration of La(NO₃)₃ has promote effect,while higher concentration has restrain effect.Soaking seeds with 30 mg/L La(NO₃)₃ could play an important role in raising healthy adzuki bean seedlings.
