Abstract
Effects of copper(0,2,4,8,16 μmol·L -1 )on the growth of Brassica juncea L.and copper induced oxidative stress were investigated.It was observed that treatments of seedlings with 416 μmol·L -1 copper for 4 d caused a remarkable inhibition of biomass of both shoots and roots,and increases in H 2O 2 and MDA contents.Activities of SOD(EC1 1 5 1 1)and POD(EC1 11 1 7)in roots and leaves increased with the increasieg of copper concentrations.Treatments of seedlings with 28 μmol·L -1 copper induced increases in APX(EC1 11 1 11)activities and production of non protein thiol(NPT)in roots.The maximum APX and CAT(EC1 11 1 6)activities in leaves were observed with copper at 4 μmol·L -1 and 2 μmol·L -1 ,respectively.
