Resistances of twelve species vegetables’ seedling to Pb 2+ ,Cu 2+ ,Cd 2+ stresses in Hoagland nutrient solution medium were studied.The results show that when the concentration of Pb 2+ is（2.00） mg/L,the highest resistance index is amaranth,and the lowest is Chinese cabbage.when the concentration of Cu 2+ is 0.50 mg/L,the highest resistance index is Lpomoea aqetica,and the lowest is cabbage.when the concentration of Cd 2+ is 1.00 mg/L,the highest resistance index is Lpomoea aqetica,and the lowest is Chinese cabbage. 铅 铜 镉 蔬菜 抗性指数 lead copper cadmium vegetable resistance index X173 2005-01-01 2021-04-01 S2
