“…The magnitude and h°of the red color is often linked to the quality of the grape since people associate certain flavors with specific colors, and thus the perception of flavor and aroma tend to increase as the color intensifies (Keller, 2015). The greater acceptance of the berries subjected to S-ABA application in this study are consistent with the results obtained in 'Sovereign Coronation' grapes treated with S-ABA, with an improvement in the attractiveness, color, and preference of the clusters when the visual-sensory analysis was assessed (Reynolds et al, 2016).…”

The application of S-ABA enantiomer to clusters of poor pigmentation cultivars can improve grape color. The aim of this study was to assess whether S-ABA applied to clusters of the new hybrid ‘BRS Melodia’ seedless grape can improve its color characteristics and to evaluate the consumer acceptance. The following treatments were evaluated: Control; S-ABA at 200 mg·L−1 7 days after veraison (DAV); S-ABA at 400 mg·L−1 7 DAV; S-ABA at 200 mg·L−1 7 DAV + 200 mg·L−1 21 DAV; and S-ABA at 400 mg·L−1 7 DAV + 400 mg·L−1 21 DAV. To apply the treatments, clusters were sprayed using a backpack sprayer until runoff. The exogenous application of S-ABA significantly improves the color of berries of ‘BRS Melodia’ seedless grape, particularly at a concentration of 400 mg·L−1 in two applications, at 7 DAV and 21 DAV, resulting in clusters with greater consumer acceptance through visual-sensory analysis. Regardless of concentration or application timing, there was no change in the physicochemical characteristics of the berries or clusters, nor in the number of shoots per cane or clusters per shoot in the season after its application.

“…The soluble solids content in harvest musts were similar in grapes treated with ABA and untreated (Table 2), consistent with other authors' findings (Amiri and Parseh, 2011;Delgado et al, 2004). Nevertheless, as with ethephon, ABA tended to decrease the TA and raise the pH of the must in all seasons studied, which is consistent with previous results obtained in table grape cultivars (Omran, 2011;Peppi et al, 2007;Reynolds et al, 2016;Yamamoto et al, 2015). However, most studies in the literature have not observed changes in must TA associated with the application of ABA (Cantin et al, 2007;Delgado et al, 2004).…”

“…When ABA is freely marketed at a reasonable cost (Zhu et al, 2016), its exogenous applications can be used as a tool to enhance grape quality and control abiotic stress. ABA treatments at veraison have resulted in significant increases in coloring and anthocyanin concentration in table and wine grapes, as does ethephon (Amiri and Parseh, 2011;Delgado et al, 2004;Koyama et al, 2014;Peppi et al, 2007;Zhang and Dami, 2012;Reynolds et al, 2016;Zhu et al, 2016). In most cases, the applications had little effects on the content of soluble solids or titratable acidity.…”

Exogenous ethephon and abscisic acid (ABA) treatments are used worldwide to improve the coloring of red table grapes, but there is little information about their impact on the quality of white grapes and wines. The aim of this work was to evaluate the effects of exogenous ethephon and ABA applications at veraison on the composition of 'Verdejo' white grapes, and on the quality of their wines. To attain this objective, a field trial was carried out in a 'Verdejo'/110 Richter vineyard located in north-central Spain. Two levels of ethephon (0 and 1500 mg L −1) and ABA (0 and 800 mg L −1) were sprayed on clusters at veraison, in a factorial design for three consecutive seasons. Ethephon and ABA had additive effects, decreasing titratable acidity and increasing pH of the must, which could be exploited by accelerating the grape ripening process in cold-climate zones. Nevertheless, each growth regulator affected the composition and sensory analysis of the wines differently. Ethephon treatments produced wines with lower concentration of acids and better flavor quality than those made from untreated plants, while wines with ABA applications tended to have a higher ethanol concentration and poorer aroma quality than controls. The wines submitted to treatments with ethephon obtained the best overall evaluation in the sensory analysis throughout the trial.

“…They demonstrated that ABA significantly increased berry weight. On the other side, González et al, 2012;Ferrara et al, 2015 andReynolds et al, 2016 and other investigators found that ABA had not a significant effect on yield components or berry weight.…”

Experiment was carried out throughout two successive seasons of 2016 and 2017 on Flame Seedless, Ruby Seedless and Thompson Seedless grapevines grown at the Experimental Orchard of Assiut University, Faculty of Agriculture. The aim of this study was to assess the impacts of abscisic acid (ABA), cluster thinning and their combinations with GA 3 on yield weight of three important grape cultivars grown under hot region. Data revealed that, the application of abscisic acid (ABA) increased yield weight (kg/vine), while cluster thinning decreased it. During the 1 st season of study (2016), all individual ABA treatments and ABA at 400 ppm combined with GA 3 at 10 ppm significantly increased yield weight (kg/vine) comparing with the control treatment. As a result of ABA treatments at 200, 400 and 600 ppm and ABA at 400 ppm plus GA 3 at 10 ppm, the yield was increased by 15.5%, 10.5%, 9.8% and 9.2%, respectively. During the 2nd season of study (2017), only ABA at 600 ppm treatment significantly surpassed the control treatment with an increment percentage of 20.5%. The rest of treatments either had no effect or reduced the yield weight comparing with the control. On the other side, cluster thinning by removing 30% of the total clusters that the vine bearing significantly reduced the yield weight (kg/vine) during the two studied seasons. As a result of such treatment, the yield was reduced by 37.2% and 39.2% in 2016 and 2017 seasons, respectively.
