| dc.description.abstract | The study was conducted to determine the behavior of grapes treated with GA3 applied at full bloom at the concentration of 250 ppm. One kilogram of freshly harvested berries was placed in either polyethylene bag (8" x12' x0.08 mm) or newsprint and stored under ambient and air-conditioned room. The experiment was set-up following the Completely Randomized Design. GA3 application reduced the number of seeds and width of individual berry resulting in reduced berry weight and cluster weight. Berry length and number of berries/ cluster remained the same. Daily weight loss was greater in GA3-treated berries, unbagged and stored at ambient condition. Lower weight loss was observed in controlled berries placed inside the polyethylene bag and stored inside an air-conditioned room. Total soluble solids remained the same in all treatments during the first four days of storage. On the fourth day onwards, GA3 treated berries and unbagged registered higher total soluble solid. The ph of the berries was relatively low ranging from 3.47 to 3.98. Higher pH values were noted o GA3 treated berries in polyethylene bag and stored in ambient condition. Titratable acidity decreased with time. On the tenth day of storage, GA3 treated berries had the lowest titratable acidity while bagged berries had higher titratable acidity than unbagged berries. | |
