Apple fruit size, in addition to the characteristics of varieties, mainly by the number of cells in the fruit, and the size of the cell size. Fruit development in the late, is the phase of cell volume increase. During this period, the vacuoles in the cells increased, the moisture content increased greatly, and the carbohydrate content in the fruits also increased linearly.
