Response of Pusa Seedless, a cultivar of Vitis vinifera to 4‐chlorophenoxyacetic acid (4‐CPA), kinetin, uracil and gibberellic acid (GA) separately and in combinations was tested. Dipping the clusters in GA at 50–100 mg/1 at 2–3 days after full bloom significantly increased the bunch and berry weight of Pusa Seedless Grape. 4‐CPA and uracil treatments increased the bunch and berry weight to some extent but not as effectively as GA treatments and kinetin had no effect. GA proved to be the best in increasing the berry weight of this cultivar. A synergistic effect was observed when 4‐CPA was combined with GA at 50 mg/1 but combinations of 4‐CPA with higher concentrations of GA did not show such synergistic effect. In general, GA alone and especially in combination with 4‐CPA lowered the quality of the berries. Uracil on the other hand, improved the quality when applied alone and in combination with GA.
