摘要: 近年来,随着工业上的矿产开发与冶炼,农业上的污水灌溉、化肥和农药的施用,导致重金属镉污染日益严重。重金属镉毒性很强,不仅影响植物的生长,还可以通过食物链,危害动物和人体健康,是重金属污染中最危险的污染物之一。据有关研究,油菜对镉具有较强的耐受性和较高的吸收性,具有修复土壤镉污染的潜力。本文综述大量的前人研究成果,从镉在油菜中的吸收、运输、积累及再分布、镉胁迫对油菜生长发育的影响、以及油菜的耐镉机制三个方面论述了重金属镉对油菜的影响及油菜对镉的抗御及耐受机制,为镉污染农田油菜高效种植及油菜高效吸镉提供理论支持。

Abstract: In recent years, the cadmium pollution is progressively serious with the rapid development of mineral industry and smelting, sewage irrigation, application of fertilizers and pesticides. The cadmium with strong toxicity is one of the most dangerous heavy metals, which not only affects the growth of plants, but also harms human and animals health through the food chains. Owing to the strong absorption and high tolerance to cadmium, oilseed rape has the potential to renovate the polluted soil. This paper aims to review and synthesize the information on the impacts of cadmium on oilseed rape from three aspects, Ⅰ the absorption, transport, accumulation and redistribution of cadmium in oilseed rape, Ⅱ impacts of cadmium on growth of rape, Ⅲ the tolerance mechanisms of rape on cadmium. It provides theoretical support of high efficiency planting and absorption of cadmium in cadmium-polluted farmland.
