【目的】土壤重金属污染越来越严重，迫切要求农作物品种具有抗污染和低积累的特性。本研究对华南地区主栽春播大豆品种的重金属抗性做评价，为生产上品种选择提供依据。【方法】采用盆栽试验比较研究了华南地区11个春大豆品种镉（ Cd ）抗性的差异。【结果和结论】以根、茎叶和籽粒的相对干质量为指标进行聚类，桂春8号、华春1号属于Cd耐性品种，泉豆7号、福豆234、华春2号和本地2号属于Cd敏感性品种。华南地区春大豆的Cd抗性存在显著差异，其中抗性品种可在重金属污染地区种植。

[Objective]The tolerant varieties are necessary because the areas of agricultural soil contami-nated with Cd is increasing .The objective of the present study was to explore the Cd tolerance amonge spring-sowing soybean varieties in South China .[Method]A pot experiment was carried out in the green-house to explore the Cd tolerance of 11 soybean varieties in South China .[Result and conclusion]The biomass and yield of all soybeans varieties decreased significantly at 10.0 mg · kg -1 Cd compared with that of the control .Based on relative biomass and relative dry seed mass , Guichun 8 and Huachun 1 were tolerant varieties , while Guizao 1 , Fudou 234 , Bendi 2 and Huachun 2 were sensitive varieties .The re-sults indicated that there are significant differences in Cd tolerance among spring-sowing soybean varieties in South China .
