An investigation was performed to study the impact of CPPU (alone and in combination with other PGR’s) and their application stage on berry development, yield and quality in grape (Vitis vinifera L.) cv. Italia at Horticultural College and Research Institute, TNAU, Coimbatore. Treatments were imposed over the vines pruned to standardized pruning level of pruning 50% of canes for crop yield and 50% of canes for vegetative growth and observed for impact on bunch and berry characters. The results revealed that bunches sprayed with CPPU (1 ppm) recorded the maximum berry width at pea stage of 7-8 mm berry size. The maximum peel weight, peel thickness and pedicel thickness was registered with CPPU (1 ppm) imposed both at 2-3 mm and at 7-8 mm berry size stage. But, the results on yield related traits found to be positive with the bunch sprays of GA3 (10 ppm) + Brassinosteroid (1 ppm) at 7-8 mm berry size.
