探讨在镉(Cd)胁迫下水稻植株内的镉含量,以及水稻不同部位镉累积情况,筛选出高耐镉性且高产的水稻品种.以不同粳稻和籼稻品种为研究对象,通过盆栽试验,在不加镉与镉胁迫2种处理下,探讨不同水稻品种收获期的Cd含量,Cd累积情况.2种处理下水稻体内镉含量大致都为根＞茎＞叶＞谷壳＞籽粒,且镉主要集中在根部;镉在不同水稻品种内的累积与分布存在差异,尤其是镉在籽粒中的累积差异较大,8个中稻品种中籽粒镉含量以品种‘春优84’的增加幅度最低,表现出较低的镉累积能力;同时也表明镉胁迫下粳稻镉累积量高于籼稻;在镉胁迫处理下籼稻产量显著减少,而粳稻产量均增加.‘春优84’籽粒镉含量增幅最低,表现出显...

To screen the high-Cd resistance and high-yield rice varieties, Cd contents in rice plants and Cd accumulation in different parts of rice under the Cd stress were studied. Taking different varieties of japonica and indica rice as the research objects, Cd contents and Cd accumulation of different rice varieties in harvest time were discussed by pot experiment, under two treatments of no adding Cd and Cd stress. Under the two treatments, Cd contents in rice plants were generally root〉stem〉leaf〉 chaff〉rice, and Cd mainly concentrated in roots....
