The rhythmical motion and the electric potential oscillation of growing higher plants were simultaneously measured. We have developed the measurement system made up with an image processing unit and a multichannel voltage data acquisition unit. We observed that shoot apex had rotational motion and leaf had the rhythmical action of opening and closing. The electric potentil at stem surface also oscillatory changed with time. The rhythmic phenomena in motion and electric potential had no correlation, whereas leaves formed in one pair each on a opposite side of a stem moved synchronously and the electric signals at a point and the neighborhood were strongly correlated. It was found that two separated shoot apexes were frequently rotated synchronously. This synchronization was varnished when a partition in the center of two apexes was put. This result helps us in supposing an existence of the chemical communication.
