Here, we investigated various cultivation conditions that are considered to affect the berry enlargement of Vitis vinifera. L. 'Shine Muscat.' Data from nine commercial vineyards showed that cultivation conditions affected the weight and Brix of berries that were different among the locations. Berry quality was influenced both by the lateral leaf number from the bunch to the base and berry quantity. The effects of shoot growth and bunch position on berry enlargement were investigated at the vineyard of the Ibaraki Agriculture Center. The results showed that berry enlargement was positively correlated with the leaf blade length at the bunch position and the lateral leaf number between the bunch and the base. Berry weight was increased by the vigorous shoot growth and the careful removal of resprouted lateral leaves, but not by the shoot growth when resprouted lateral leaves were left on the plant.
