Abstract
Methods of separation and characterization of Cd in Zea Mays L. were studied by means of a radioisotopic technique based on injecting 109 Cd into the plant. Two classic methods for fractionating plant material were compared. Cd was found to occur in all different cell components and a significant activity of Cd in the intracellular liquid is bound to proteins as indicated by chromatography on a molecular sieve. Cd fixed to cell walls exchanges entirely after selective solvent extraction with H z O, KN0 3 HAc, HC1. Our results indicate Cd-binding sites in stems.
