Abstract:
Lycium ruthenicum Murr.seedlings were treated with different medium contained 0,50,100 and 200 mmol?L-1 NaCl for 10 days,root length increasement,contents of anthocyanin in leaves,proline,MDA,soluble protein,activities and isozymes of POD and SOD response to salinity were analyzed.The effect of different concentration medium of NaCl on physiological and biochemical characteristics of Lycium ruthecium Murr.seedling was studied,which to detect mechanism of the plant adapt to salinity condition and provide scientific basis for future utilizing.The results showed that the increased root length was not influenced by 0-200 mmol?L-1NaCl stress medium.In 200 mmol?L-1 NaCl condition,anthocyanin in leaves was raised up and reached the highest level.The content of proline and MDA were not changed significantly under 0 to 100 mmol?L-1 NaCl stress,while all the characteristics elevated in response to 200 mmol?L-1 NaCl.With the increasing salinity,the activity and expression of SOD isozymes were stabilized.POD avtivity showed a trend of first rising and then falling along with the salt concentration increasing,the maximization activity was 1 065.9 U?g-1?min-1 in 100 mmol?L-1 NaCl medium.Isozymes of POD 1 and POD 2 were correlated with seedling salt tolerance.
