Tow-year-old Potentilla fruticosa L.cuttings grown in pots were treated with solution containing 0,0.2%,0.4%,0.6%,0.8% and 1.0% of NaCl and Na2SO4,respectively.Changes in physiological and biochemical indicators of leaves associated with salt tolerance were investigated at the 7th and 13th day.In order to research and develop salt tolerance of wild shrubs for saline areas.The results showed that with the increasing of NaCl and Na2SO4 concentrations and the prolonging of salt-stress time,cell membrane permea...
