In this paper, uptake and elimination of lanthanum by excised roots of Triticum aestivum L. in various conditions were studied. Lanthanum concentrations in the roots were determined by neutron activation analysis. Results showed that the uptake of La in the excised root was almost independent of vitality, and the bonding of La with the roots was tight, but could be removed by EDTA treatment. There was significant dose-dependent accumulation of La in the excised roots within the experimental concentration (0–40 µmol/l).
