| 摘 要： | 用不同浓度镉 (Cd2 )处理小麦种子 ,结果表明 ,Cd2 浓度高于 10 - 4m ol/ L 时 ,小麦种子萌发、幼苗地上部生长均受到抑制 ,并与对照差异达显著水平 ;当 Cd2 浓度高于 10 - 5m ol/ L 时 ,根系生长受抑制 ,并与对照差异达显著水平 ,随着 Cd2 浓度的增加 ,根系活力下降 ,细胞膜透性增大 ,膜脂过氧化产物丙二醛含量增加 ,根苗比下降

| Abstract: | The wheat seeds were soaked in the solution with different concentration of Cadmium (Cd 2 ). The results showed as follows: the wheat seed germination and seedling growth were inhibited when Cd 2 ]>10 -4 mol/L and the root growth was inhibited when Cd 2 ]>10 -5 mol/L. The difference was significant with the contrast. With the increase of Cd 2 concentration, the root activity reduced and the cell membrane permeability and MDA content increased, root shoot ratio reduced. |
