查询词典 oxidating

The mechanisms for the differences among rice cultivars in Cd uptake and translocation There were significant differences in root oxidating abilities and soil redox potential between two typical rice cultivars, Shan you 63 and Wu yun jing 7, that are greatly different in Cd uptake from soil. The root oxidating abilities and soil Eh were accordant with Cd uptake for the cultivars. The difference between the two cultivars in Fe concentrations of root iron plaque was also significant. The cultivar with higher Fe concentrations in root iron plaque absorbed less Cd from soil.

四、水稻不同品种对镉吸收及分配存在差异的生理机理对土壤中Cd吸收能力差异很大的水稻不同品种间，根系氧化力和土壤氧化还原电位有显著差异，品种的根系氧化力和土壤氧化还原电位与该品种对Cd的吸收能力间有很好的一致性；水稻不同品种间，根表铁氧化膜的含铁量有显著差异，根表铁氧化膜含铁量高的品种，对土壤中Cd的吸收能力低；盆栽水分腾发量高及根系伤流液Cd浓度高的品种，吸收积累Cd的能力强。
