    摘要:

    【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.

    Abstract:

    【Objective】The tolerant varieties are necessary because the areas of agricultural soil contaminated 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 greenhouse 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 results indicated that there are significant differences in Cd tolerance among spring sowing soybean varieties in South China.
