Abstract:: Taking Lonicera japonica“Jinhua No.3”as materials，the variation of physiological indexes in L.japonica，such as the contents of malondialdehyde(MDA)，proline，soluble sugar，and the activities of superoxide dismutase(SOD) and peroxidase (POD) under various concentrations copper stress were studied.The results showed that the copper damage phenomenon of L.japonica was present with the accumulating copper in Hoagland nutrient solution.The activities of SOD and POD demonstrated change rules with different copper concentrations that were raise under low concentrations treated(100 mg/L and 200 mg/L) and reducing under high concentrations treated (400 mg/L and 800 mg/L).And MDA content was reducing in different degree after copper stress 8 days.Proline content rose rapidly first then reduced.The soluble sugar content was lower first then rising after 6 days.Between the contents of proine and soluble sugar had compensating effect.L.japonica could normally grow that copper content was less than 25 mg/L environment. L.japonica was a good plant for resistance copper stress.
