中文摘要：
本工作在实验室条件下研究磁化水对玉米耐受重金属镉的影响．测定了几种抗氧化酶的活性，与对照组相比，磁化水处理的植株叶片超氧化物歧化酶和过氧化氢酶活性提高，丙二醛含量减少．因此提出，在重金属镉的胁迫下，磁化水可通过提高超氧化物歧化酶和过氧化氢酶活性，消除镉引发的氧化胁迫，保护了细胞膜的完整性（具体体现为植株体内丙二醛含量较低），从而增强植株对重金属镉的耐受性，使植株免受或减缓伤害．对我国受Cd污染地区玉米的种植具有一定的指导意义．
英文摘要：
In this study, we investigated the effect of magnetic water to the Cd-induced corn＇s phenotype in the laboratory. In mechanism, the corn flooded by magnetic water display higher SOD and CAT activities and lower concentration of MDA than the control corn. Thus we concluded that Cd can induced oxidant stress in normal conditions, however, flooding of magnetic water increased the SOD and CAT activities, from this result, the concentration of MDA can be decreased in vivo, and the tolerance to the metal pollution can be improved. These conclusions have significant value for culture of corn and other crop in metal polluted area.
