Abstract

With seedlings of Phaseolus vulgaris as material,sand culture were adopted,root activity,chlorophyll content,resistance physiology rule(proline,MDA,SOD,POD) were tested under 15,30,60,90,150,200 mmol/L NaCl stress.The results showed that root activity,SOD activity and POD activity showed increasing first and then decreasing trend with Na+ stress concentration increased.The maximum value was reached under 30,150,90 mmol/L NaCl stress,112%,198% and 219% than the control,content of chlorophyll a,b decreased with the stress of Na+ concentration increased,but content of MDA and proline increased.
