The change in cell size with fruit development and the accumulation of sugars in fruits have been investigated independently in many kind of fruits. In this report the relationship between cell size and the kind of sugars accumulated was investigated using Delaware grape berries and melon fruits. The size of cells of grape berries at 65 DAA (days after anthesis) was 144 μm and the sucrose, glucose and fructose content was 13.5 g l-1, 81 g l-1 and 87 g l-1, respectively. On the contrary, the size of cells of melon fruits at 50 DAA was 261 μm and the sucrose, glucose and fructose content was 54 g l-1, 18 g l-1 and 18 g l-1, respectively. It is suggested that glucose and fructose accumulate preferentially in grape berries, which has a large number of smaller cells, but sucrose accumulates preferentially in melon fruit, which has a great number of larger cells.
