As the bunch of grapes grows, some beads remain small rather than large. This is called short sum. Possible causes of short flowering include poor pollination, malformation of flower parts. Carbohydrate (CHO) deficiency causes difficulty in flower development into seed. If GA is used in the early stages, the amount of short sum increases. Cold or fog during fruiting. Boron and zinc deficiency. This also happens when the vine is infected with a virus. In order to prevent this distortion, g. A. Similar organisms should be used. Micronutrients should be given in proper quantity. The number of bunches should be kept in proportion to the number of leaves, so that carbohydrates are not reduced. Thinning of bunches should be done at the right time. That means there will be no short bridge. After the grapes begin to ripen, some of the beads in the bunch are pale in color, soft in texture, have no heat, no sweetness, only sour water. These beads are spread here and there throughout the bundle. If the material is left on the tree for a long time, these beads dry up and sometimes fall off. It reduces overall weight. These beads dry quickly after the grapes are plucked from the tree. Therefore, boxed goods look bad in the market. These beads are called 'water beads'. The possible reasons for this formation are as follows: failure of the stem, water stress during bead feeding, excess nitrogen, lack of calcium supply to the grape bunches. If there are too many grape bunches on the vine, the nutrients are reduced, if the grape bunches are thickened, the cells of the beads (xylem) are suppressed and there is no further food supply, due to which the waterberries grow, if we consider the reasons mentioned above, we can definitely reduce the waterberries. But all the measures should be done when the fruit is bearing. If the nutrient content of the soil and cane is tested before pruning, the nutrients can be managed accordingly.
