Grape vines of cultivar 'Parletta' were sprayed with GA3 at 10 (G1), 15 (G2), 20 (G3), 30 (G4) or 40ppm (G5) when cluster was 7-12cm length (S1), at full bloom (S2) or when berry was 2-4mm (S3). Treatments were as the following combinations: Water spray (T0) as a control, G1S1 (T1), G1S1 + G2S2 (T2), G1S1 + G3S3 (T3), G1S1 + G5S3 (T4), G2S1 (T5), G2S1 + G2S2 (T6), G2S1 + G4S3 (T7), G2S1 + G5S3 (T8), G3S2 (T9), G3S2 + G4S3 (T10), G3S2 + G5S3 (T11), manual thinning by comb (T12), pruning to 50 eyes (T13) or girdling vine arms (T14). Treatments T6 and T1 produced the highest yield kg vine-1 where T7 and T6 had the highest number of clusters vine-1. The heaviest clusters were produced in T13, T1 and T14. The treatments increased berry weight than control. Cluster length did not change significantly where the heaviest berries were produced in T13, T9, T5 and T3. The lowest cluster compactness was in T11, T9, T8, T14, T7 and T4. Shot berries % showed the lowest percentages in T8, T14, T4, T3 and T5. Fruit total soluble solids (TSS) increased in T5, T3, T12 and T13. Titratable acidity had the lowest values in T3, T14 while T12. TSS /acid ratio induced the highest ratio in T3, T12, T14 and T13.
