title: [The absorbed rate and distribution rule of rare earth elements in wheat by 141Ce as tracer].
abstract: The study on absorption, distribution rules and transportation rates of cerium in the interface of water-wheat by 141Ce in culture solution were carried out. The results showed that the concentrations of cerium in wheat seedling were gradually increased during the experiment, and so did the same after increasing the concentration of cerium adding in the culture solution. The concentrations of cerium in roots of winter wheat were significantly high than that in tops (steam & leave). The absorption rates of cerium in wheat with different treatments of cerium were distinct. The quantitative formulas, which describe the rule of absorption rate and culture time, was given resulting from the fit of the experimental data.
