在1968年，每隔2周，对当前和1年树龄的针进行淀粉、总糖、果糖、葡萄糖、蔗糖、棉子糖、粗脂肪和水分含量的测定。描述、比较了各龄期针叶水分和碳水化合物含量的季节性波动，并将其与碳水化合物生产和利用的季节性变化联系起来。
Starch, total sugar, fructose, glucose, sucrose, raffinose, crude fat, and moisture contents were determined for current and 1-year-old needles at about 2-week intervals throughout 1968. Seasonal fluctuations in moisture and carbohydrate content of each age of needles are described, compared, and related to seasonal changes in carbohydrate production and use.
