  • The anatomical diagnoses derived from the adventitious buds, the dimples, and their surroundings, which break out often in the Populus alba ${\times}$ P. glandulosa, were investigated by the light microscope. In the anatomical structure derived from the adventitious buds, the vessel seldom occured, the diameters of the cell were smaller and the wall thicknesses were thicker than those of the normal woods. The wood fibers around the adventitious buds were crooked, frequently had the septa, and the adjacent rays showed the multiple rows. The wood fibers of the dimples were extremely crooked from pith to the hark direction and the rays showed the multiple rows. The vessels in the line-like discoloration zone around the adventitious buds and the dimples formed the traumatic tyloses.
