Kinetin influenced the rate of absorption of k+ and that of K+/H+ antiport of the roots of corn seedlings. The effect of kinetin on ion transport correlated with its effect on K+ATPase acitivity of the roots. Kinetin on enzyme activity seemed to be direct and specific since kinetin (1.25x10-6M) and not its physiological inactive analogue-adenine, stimulated K+ATPase activity (50-60%) in vitro. It is suggested that the effect of kinetin on ion transport is mediated directly by K+ATPase of the root cell membrance.
