In branches of the upright type of Japanese cherry reacting on the gravity stimulation, tension wood were formed by the action of gibberellin in the secondary xylem and caused negative gravitropism . The fine structures of the endodermal starch sheath cell of both types of cherry were similar. These results suggest that the abnormality of the gravi-response in the weeping Prunus trees is not due to the abnormal development of gravi-sensor.
