In wood cylinders obtained from trunks of 10 Picea abies trees, the fluctuation in the concentrations of glucose, fructose, sucrose, raffinose, starch, free glycerol, and glyceride glycerol was followed for one year. The determination of the compounds was done enzymatically. In the winter months sugars and free glycerol showed maximum concentrations. Before the onset of growth ring formation and leaf unfolding the concentrations of sugars and free glycerol decreased. In August, raffinose was absent. Starch content rose in spring, decreased during the summer months, and than rose again in autumn. Glyceride glycerol ( = fat) content was low in the cold period, but high in spring and summer. A cold period in midsummer induced a temporary accumulation of sugars in the xylem tissue of the Picea trunks.
在从 10 棵欧洲云杉树干中获得的木筒中，我们对葡萄糖、果糖、蔗糖、棉子糖、淀粉、游离甘油和甘油酯甘油的浓度变化进行了为期一年的跟踪研究。这些化合物的测定是通过酶法进行的。在冬季，糖和游离甘油的浓度达到最高。在生长轮形成和叶片展开之前，糖和游离甘油的浓度下降。在 8 月，棉子糖不存在。淀粉含量在春季上升，夏季下降，然后在秋季再次上升。甘油酯甘油（即脂肪）含量在寒冷时期较低，但在春季和夏季较高。仲夏的一段寒冷期导致云杉树干的木质部组织中暂时积累了糖分。
