USE OF BIOREGULATORS TO IMPROVE THE QUALITY OF SHARAD SEEDLESS GRAPES

Studies conducted to standardize the dose of GA3 and 6BA at 3–4 mm and 6–7 mm berry size stages after berry set, indicated that the application of GA₃ at 40 ppm + 10 ppm 6BA at 3–4 mm and GA₃ at 30 ppm + 10 ppm 6BA at 6–7 mm berry size stage was equally good in comparison with the higher concentration of GA₃ at 50ppm + 20 ppm 6BA at 3–4 mm and GA₃ at 30 ppm + 10 ppm 6BA at 6–7 mm berry size stage.
Berry quality and shelf life were not significantly different among the treatments.
Based on the results obtained it could be concluded that for increasing berry size and berry weight of Sharad Seedless grapes the application of GA₃ at 40 and 30 ppm along with 10 ppm 6BA at 3–4 mm and 6–7 mm berry size stage, respectively seems to be beneficial and economical.
