Abstract:
In order to investigate the physiological adaptation of Begonia semperflorens Link et Otto seedlings to NaCl stress,and determine its tolerance threshold,the effects of NaCl stress with different concentrations on the growth and physiological indexes were studied with one-year-old potted seedlings of Begonia semperflorens.The results showed that with the increasing of NaCl concentration,the relative conductivity of leaves increased gradually,plant height growth decreased,and fresh weight and dry weight of whole-plant decreased.The seedling growth was obviously inhibited.With the increasing of NaCl concentration,the content of MDA increased and activity of SOD decreased.The content of soluble protein decreased and free proline increased,and there were a significant negative correlation between them.The activity of POD and the content of soluble sugar increased first and then decreased.In the whole process of osmotic regulation,free proline and soluble sugar played an important role of osmotic adjustment.The salt tolerance threshold of Begonia semperflorens seedlings was 242.67 mmol?L-1,when taking 50% drop in whole-plant dry weight as standard.
