In this study, the effect of preharvest 24-eBL (a BR analogue) applications on the accumulation of anthocyanin of Horoz Karasi grape cultivar was examined. 24-eBL was applied to vines with 13 combinations including different application times (veraison, 7 days after berry set + veraison, 7 days after berry set + veraison + 30 days after veraison) and 4 different concentrations of 24-eBL (0.2, 0.4, 0.6 and 0.8 mg/L) and control. As a result of the study, the highest anthocyanin content was obtained from the vines applied with 0.2 mg/L of 24-eBL at 7 days after fruit set and at veraison stages in both years (respectively, 47.98 and 71.16 mg/100 g FW).
