“…Therefore, being other factors equivalent, the same degree of water stress is expected having an higher impact on yield and grape quality pre-veraison rather than post-veraison. A number of papers (Basile et al, 2011;Girona et al, 2009;Intrigliolo et al, 2016;Junquera et al, 2012;Merli et al, 2015Merli et al, , 2016Munitz et al, 2017;Shellie and Bowen, 2014) have confirmed this although response variability within each phenological stage can be substantial. The most consistent response to pre-veraison is a yield limitation primarily driven by a reduction in berry size.…”

“…In contrast, Salon et al [36] and Girona et al [37] stated that a significant difference was observed in 'Pinot Noir' and 'Bobal' when a severe water stress was applied. Moreover, in 'Merlot', Bucchetti et al [38] reported a positive effect of water stress on anthocyanin concentration, whereas Merli et al [39], in 'Sangiovese', stated that total anthocyanins and phenolics were neither affected in vines under well-watered conditions or subjected to progressive post-veraison water stress. Furthermore, must composition could be influenced by genetic factors.…”

Effects of Vine Water Status and Exogenous Abscisic Acid on Berry Composition of Three Red Wine Grapes Grown under Mediterranean Climate

Beyond climatic conditions, qualitative performance is led by the intrinsic characteristics of the genotype. The aim of this study was to investigate the relationship between vine water status and exogenous abscisic acid (ABA) application on berry composition of the cultivars Cannonau, Merlot and Sangiovese. The experiment, carried out in 2016 and 2017, consisted of comparing two levels of irrigation treatments, full irrigation versus a non-irrigation treatment. Within each treatment, two sub-treatments were set up: (i) 4 mL L−1 of exogenous ABA applied at veraison to clusters only and subsequently repeated after six days; (ii) a control (untreated vines). The application of different irrigation regimes confirmed that the response to water stress is highly cultivar-dependent. Berry composition was influenced differently among cultivars by water stress. In terms of metabolites, positive influences were observed with Cannonau. No significant effects were observed by spraying exogenous ABA directly on grapes. Moreover, no significant interactions were found between the application of water stress and ABA. Exogenous ABA application did not appear to be a viticultural practice capable of influencing must composition in environments characterized by severe environmental conditions such as heat and drought.

“…It has been previously reported that water deficit can lead to smaller berry size in Cabernet-Sauvignon (Intrigliolo et al, 2016), Sangiovese (Merli et al, 2015) and Tempranillo (Zarrouk et al, 2012) in Mediterranean-type climates. Productivity was lower in the two French cvs.…”

Aim: The aim of this study was to determine and compare anthocyanin content and profile under variable irrigation regimes in four red grape cultivars (Vitis vinifera L.), the Greek indigenous cvs. Agiorgitiko and Xinomavro, alongside Syrah and Grenache noir.Methods and results: Three irrigation treatments were applied in a 6-year-old vineyard comprising all four varieties in a block design, starting at bunch closure (E-L 32) through harvest of 2012 and 2013: full irrigation (FI) at 100% of crop evapotranspiration (ETc), deficit irrigation (DI) at 50% of ETc and non-irrigated (NI). The identification of the compounds was performed by HPLC. Results showed that, under the hot summer conditions of the Greek climate, the four cultivars had a similar response regarding vigor and yield parameters, with values increasing with water supply. Anthocyanin concentration was maximized under non-irrigated conditions in all cultivars, but anthocyanin profile and relative distribution of individual anthocyanins among irrigation treatments showed a strong cultivar effect.Conclusion: Xinomavro seemed to favor the synthesis of more stable forms of anthocyanins under limited water supply (acylated over non-acylated and tri-oxygenated & methoxylated on the B-ring over di-oxygenated & hydroxylated) while Agiorgitiko had an opposite behavior, which might imply a need for a different irrigation strategy.Significance and impact of the study: To the best of our knowledge, this is the first comparative report of anthocyanin composition and profile in berry skin, under contrasting water status, for the two most important red winegrapes of Greece.
