摘要：

Ultrastructural changes in the winter embryonic shoot of Norway spruce are described. In January some cell elements did undergo considerable changes, even within several days, while morphological and anatomical changes were not observed. These ultrastructural changes were observed primarily within plastids (starch accumulation) and tannin vacuoles (the disappearance of aldehyde groups). A glucose released from tannins seems to be utilized for starch synthesis at the time of breakage of winter dormancy.
