Abstract:
Taking ‘Jinlv No3’ seeds as materials,cucumber seedling roots were stressed with four concentrations of NaCl mixed with NaHCO3 at same proportion,and the physiological metabolism regulation were studied.The results showed the activities of SOD,POD,and content of soluble sugar and MDA were increased by composed of NaCl and NaHCO3.When 30 mmol/L NaCl+30 mmol/L NaHCO3,activities of SOD,POD,and content of soluble sugar were significantly different compared with CK.Activities of MDA was not significantly different compared with CK.And the results revealed that cucumber seedling roots could grow in 30 mmol/L NaCl+30 mmol/L NaHCO3.
