The present investigation was conducted to study the effect of foliar application of Gibberellic acid (40% WSG) and CPPU (1% SP) with regards to the concentration, stage and time of application on yield, quality, leaf photosynthesis and biochemical changes in berries of grapes. The experiment was conducted at National Research Centre for Grapes, Pune during fruiting season of 2013-2014 on Thompson Seedless grapes. Foliar application of different concentrations of Gibberellic acid (GA3) 40% WSG and 90% active ingredient while CPPU 1% SP was given at pre-bloom, flowering, 3-4 mm berry size and 6- 7mm berry size stage as a spray. Application of 40 ppm GA3 (40 % WSG) alone or in combination with 2 ppm CPPU (1% SP) was found to increase leaf photosynthesis, transpiration rate and also biochemical parameters viz. Protein content, starch and total carbohydrate in Thompson Seedless grapes. Positive correlation was recorded with berry quality, leaf photosynthesis and biochemical parameters in relation to yield. The data from this study indicated that spraying of 40 ppm GA3 (40 % WSG) alone or in combination with 2 ppm CPPU (1% SP) found to be effective for improving leaf photosynthesis, biochemical changes, quality and yield parameters in Thompson Seedless grapes.
