The present study was conducted during the two consecutive seasons 2018 and 2019 on "Crimson Seedless" table grapes to mitigate the excessive ProTon concentration by some cytokinin use. The following treatments were used: control, thidiazuron at 50ppm (TDZ), abscisic acid at 250ppm (ABA) preceded by TDZ at 50ppm, ABA at 500ppm preceded by TDZ at 50ppm, benzyl adenine at 50ppm (6-BA), ABA at 250ppm preceded by 6-BA at 50ppm, ABA at 500ppm preceded by 6-BA at 50ppm, ABA at 250ppm and ABA at 500ppm.Treatment of TDZ and 6-BA were applied at berry set while ABA treatment was applied at 10-15% berry coloration. The results showed that pre-harvest application of TDZ or 6-BA increased cluster weight, 100 berry weight, pedicel weight, berry acidity, berry and leaves chlorophylls and decreased berry coloration, TSS, total sugars. The application of ABA at 10-15% berry coloration enhanced berry anthocyanin content, TSS, Total sugars and lowered acidity and chlorophyll. The present study recommended using either TDZ or 6-BA at 50ppm followed by ProTon at 500ppm to mitigate the excessive ProTon concentration on "Crimson Seedless" grapes.
