Abstract

The passive transport processes in plants of22Na+,137Cs+,45Ca2+,65Zn2+,59Fe3+ and32PO 3−4 ions and the plant-protecting agent “Saphidon (14C)” were studied by a radioabsorption method. The parameters of the passive transport processes of212Pb2+, borate and tetraborate ions in plants were measured by quantitative microradiographic methods, using photoemulsion and solid state nuclear track detectors. Ion diffusion concentration profiles within the plants were determined at various diffusion times and temperatures. The equation of linear diffusion combined with convection was used to determine the diffusion coefficients characteristic of the transport processes.
