Electron micrographs of ‘Gleason Elberta’ peach flower buds, Prunus persica (L.). Stobes, during rest indicated only moderate metabolic activity prior to December 20. In the December 27 collection, however, a single membrane-bound body (microbody or lysosome) and rough endoplasmic reticulum (RER) were present. Also, the Golgi bodies (dictyosomes) were nearly mature. Heterochromatin disappeared on January 3. By the end of February the number of mitochondria, Golgi bodies, and vesicles had increased markedly. During the first week of March, large nucleopores were observed in the nucleus. These data indicated that bud cells were changing at cold temperatures during winter. Organellar changes were compared to the predicted date for end of rest (13).
