Abstract
CPPU at (0,3,5 and 7 ppm) and GA3 at (0,5,10 and 20 ppm) were applied separately or in combination to bunches of 6-year-old Ruby Seedless grapevines supported by Spanish Paron trellis and located in Wadi El-Faregh region, Giza governorate during 1997 and 1998 seasons. The clusters were sprayed when berry size reached 6-8 mm in diameter. The CPPU and/or GA3 treatments significantly increased berry weight, size, length and diameter. Bunch weight and yield/vine were also significantly increased. Poorly coloured berry percentage (PCBP) was increased and reached its maximum under 7 ppm CPPU x 20 ppm GA3 treatments. TSS, TSS/acidity and anthocyanin were decreased while acidity showed a reverse trend. CPPU and/or GA3 delayed grape ripening by 5 to 21 days compared to the control. This delay improved quality, colouration and increased the price.
