The study aimed to determine the optimal dose of gibberellic acid that can be applied to achieve a highersustenable production and a harmonization of quality indicators at vine variety for table grapes Coarnă neagră, grown in the areal of Iasi vineyard, Romania. In terms of experience, we found that at Coarnă neagră variety the optimal dose of gibberellin applied was 25 ppm GA3/10 L H20, that reported the most important values of productivity and fertility characteristics compared to control variant. The treatment applied to inflorescences provided an increase of production exceeding 18%, and also an improvementof marketed production percentage.The number and weight of seeds in berry remained constant and the concentration of antocyanin pigment was over 20% higher than at untreated grapes.
