摘　　要：以油橄榄根系为试材,探讨不同浓度重金属镉(Cd2+)胁迫下对油橄榄根边缘细胞的影响。结果表明,镉对油橄榄根边缘细胞产生明显毒害,随着镉浓度的增加,边缘细胞的根冠果胶甲基脂酶(PME)活性和细胞存活率都呈现下降的趋势。Taking Olea europaea root system as experiment material, author dis- cussed the effect of Cadmium with different concentration on fringe ceils of Olea Europaea roots. The results showed that cadmium had obvious toxic effect on the cells. With the increasing of cadmium concentration, the activity of pectin methyl esterase （PME） and viability of these fringe cells were decreased obviously.
