摘　　要：以6个水稻品种为试材,设置5个土壤镉浓度处理的盆栽试验,对水稻糙米中重金属镉的积累进行了研究。在不同浓度的Cd处理下,水稻糙米中Cd含量在品种间存在显著差异,而且不同水稻品种的籽粒对土壤中重金属镉的敏感性不同。结果表明,重金属镉低积累水稻品种的筛选应在土壤镉含量相近的土壤上进行。A pot experiment with six rice varieties at five cadmium stress levels was conducted to study the Cd accumulations in brown rice. Cd contents in brown rice were significantly different among the varieties, as well as the sensitivity of brown rice to soil Cd . It was suggested that screening of low-Cd-accumulation rice varieties should be undertaken in the soils at similar Cd levels.
