果树贮存营养主要是碳水化合物(以淀粉为主)、蛋白质和脂肪等。这些物质贮存于果树皮层、木质部的薄壁细肥及髓中,以地下根部贮存较多。 树体贮存的营养对越冬及下一个生长季节的萌芽、开花、抽梢、展枝、生根、坐果和果实形成等过程 Fruit trees are mainly stored carbohydrates (mainly starch), protein and fat. These materials are stored in the fruit cortex, xylem thin and fine fat and pulp, to store more underground roots. The nutrition stored in the tree can protect the plants from overwintering and germination, flowering, decapitation, spreading, rooting, fruit setting and fruit forming in the next growing season
