摘　　要：对新红星苹果的有果短枝叶、无果短枝叶、叶丛枝叶、发育枝叶中总糖、还原糖、蔗糖、淀粉含量进行了分析。结果表明,叶片中不同类型的碳水化合物含量随着叶片的迅速生长而逐渐下降,而后随着叶片的发育成熟,其含量呈逐渐递增趋势,但随着叶片的衰老又呈逐渐下降的趋势。不同枝类叶中不同类碳水化合物含量变化有一定的差异。Variations of total sugar, reduced sugar, sucrose and starch content in leaves on spur of bearing fruit, spur without fruit, clustered spur and developmental shoot of 'Starkrimsom' apple tree were studied in this experiment. The results indicated: various carbohydrate contents in leaves declined gradually along with rapid growth of leaves, then increased gradually with developmental and mature of leaves, while declined gradually with senescence of leaves.There are some differences of carbohydrate content of leaves among different branches.
