Tannin cells occur throughout the bud except the distal and peripheral meristem zones of the apical meristem, and the youngest cataphyll primordia. Starch is absent in winter buds. The earliest structural manifestation of spring awakening in the bud are fragmentation of tannin vacuoles and synthesis of starch in the green cells of the bud. The tannins occurring in the vacuoles are hydrolysable giving a positive reaction for sugars (PAS). During their spring hydrolysis glucose is released. It is probably one of the sources of sugars for the synthesis of starch. During extension growth of the bud there occurs a degradation of tannin cells in the pith, which consist in the precipitation of tannins to a condensed form.
