• The effect of ferricyanide on K^+ fluxes in epidermis and in guard cells of Commelina communis L. were studied. Ferricyanide enhanced guard cell protoplasts swelling, which results from enhanced K^+ uptake. In intact epidermis ferricyanide inhibited K^+ uptake and consequently, stomatal opening. This was found in floated and submerged epidermal tissues, indicating that the degree of contact with the solution does not affect the response to ferricyanide. Investigation of the rate of plasmolysis and de-plasmolysis of guard cells in epidermal tissue revealed that ferricyanide enhances deplasmolysis, caused by K^+ uptake, only in completely plasmolysed cells, which resemble protoplasts in situ.
