Abstract :The membrane potentials of periderm and cuticular membranes were measured with KCI and NaCl solution using Ag/AgCI electrodes. For the electromotive force insert ignore into journalissuearticles values(emf); measurements, the concentration in both compartments were brought to equilibrium with the 0.01 M concentration of KCI or NaCl solution, then the one side was kept constant and the other side changed. The estimation of the Donnan potential contribution to the membrane potential was carried out by taking into account the fixed charge concentration, Cx, value. From these measurements electrochemical characterization of the asymmetry and surface layers of the periderm and cuticular membranes can be described.
