果树贮存的营养主要是糖类(以淀粉为主)、蛋白质和脂肪等。这些物质贮存于皮层、木质部的薄壁细胞及髓中,以地下根部贮存较多。树体的贮存营养对越冬及下一个生长季节的萌芽、开花、抽梢、展叶、生根、坐果、果实形成等过程的顺利完成及结果数量、质量都有显著的影响。因此,致力于提高贮藏水平,对果树的优质、高产具有重要的作用。一年中,在果实采收后至 Nutritional storage of fruit trees are mainly sugars (mainly starch), protein and fat. These substances stored in the cortex, xylem parenchyma cells and marrow, to store more underground roots. The storage of tree body has a significant impact on the successful completion of the process of overwintering and the next growth season of germination, flowering, shoots, leaf unfolding, rooting, fruit setting, fruit formation and the number and quality of the results. Therefore, to improve the storage level, the fruit of high quality, high yield has an important role. One year after fruit harvest
