[Objective] This study aimed to investigate the characteristics of Pb and Cd uptake and accumulation in Osmanthus fragrans（Thunb.） Lour.under single and combined stress of Pb and Cd.[Method] Pot experiment was adopted with O.fragrans seedlings as experimental materials to investigate the effect of single and combined stresses of Pb and Cd on the growth of O.fragrans seedlings under 0,50,100,500,1 000 and 2 000 mg/kg of Pb and 0,1,10,50,100 and 200 mg/kg of Cd.[Result] Under the experimental conditions,the growth of O.fragrans seedlings was significantly inhibited under moderate Pb stress（500 mg/kg） and high Cd stress（100 mg/kg）;the decreasing order of Pb uptake rate of different O.fragrans tissues was root stem leaf;the decreasing order of Cd content of different O.fragrans tissues was root stem leaf,while the decreasing order of Cd uptake rate of different O.fragrans tissues was stem root leaf.[Conclusion] Under combined stress,low concentrations of Pb and Cd can mutually promote the uptake and accumulation,while high concentrations of Pb and Cd can mutually inhibit the uptake and accumulation.
