This study was carried out to determine the effects of berry thinning and gibberellin (GA3) on yield and fruit quality of ‘Reçel
Üzümü’ table grapes. A combined six treatments of gibberellin (control and 40 ppm) and cluster tipping (control, 1/3 and
1/2) were applied at the 3-5 mm berry size stage. Gibberellin was the main factor for the increase in berry size, berry and
cluster weight, and yield. Crushing resistance of berries was higher for gibberellin sprayed clusters. Fruit maturity was
delayed with gibberellin and it significantly decreased fruit color. Maturity levels of Reçel Üzümü berries increased with the
amount of berry thinning. Lengths of tipped clusters were shorter than control while there were no differences between 1/3
and ½ berry thinning. Removing parts of clusters did not influence berry and cluster sizes. The total sensory evaluation scores
were the highest for thinned grapes that had not been treated with gibberellin.
