重金属镉可使小麦幼苗细胞膜透性增大，根系活力下降，MDA积累增加，SOD，POD活性上升，且POD活性上升更为显著．这些变化都与镉浓度呈正相关．向镉胁迫溶液中加入Zn~(2+)，10~(-3)mol·L~(-1)，能使镉毒害引起的生理生化变化得以不同程度的恢复，Cd~(2+)，10~(-5)mol·L~(-1)的毒害基本可以完全解除，Cd~(2+)，10~(－4)mol·L~(-1)毒害能被绝大部分解除，但对Cd~(2+)，10~(-3)mol·L~(-1)毒害的解除效果较差，根系活力只能恢复至对照的60％．
Heavy metal cadmium could increase permeability of wheat seedling cell membrane, decreased root activity, increased MDA accumulation, increased SOD and POD activities, and increased POD activity more significantly. These changes are positively correlated with cadmium concentrations. Cadmium stress solution added Zn ~ (2 +), 10 ~ (-3) mol·L ~ (-1), can make the physiological and biochemical changes caused by cadmium poisoning to some extent, Cd 2+, The toxicity of 10 ~ (-5) mol·L ~ (-1) could be completely eliminated, and the poison of Cd ~ (2 +) and 10 ~ (-4) mol·L ~ (-1) However, the detoxification of Cd ~ (2 +) and 10 ~ (-3) mol·L ~ (-1) poisoning was poor, and the root vigor could only recover to 60% of the control.
