“…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.…”

“…Furthermore, must composition could be influenced by genetic factors. In a recent study conducted by Merli et al [7], the authors suggested that grafting the same cultivars onto different rootstocks may trigger differential gene regulation under water stress and higher temperatures leading to a different must composition. It is clear that varietal responses are the result of specific interactions between environmental, agronomic and genetic factors.…”

“…It is generally accepted that moderate water stress positively influences wine composition mainly due to the increasing skin/pulp ratio [4] and the biosynthesis of secondary metabolites [5]. While primary and secondary metabolites are positively affected by water stress, berry composition is determined by the interplay between soil water availability, atmospheric conditions [6] and genetic factors [7]. In fact, in Mediterranean environments where it is not traditionally practiced, irrigation is increasingly being used to allow berries to ripen properly as a response to ongoing climate change.…”

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.

“…Additionally, this mineral element is a cofactor of enzymes involved in respiration and photosynthesis (Jin et al 2011), which explains the results obtained in the present study. Gas exchange in grafted plants seems to be influenced by the rootstock because the rootstock can modify the gene expression, vigor, and productivity of the scion (Colla et al 2012;Merli et al 2016), as evidenced by the compatibility between scion/rootstock, the chlorophyll content (Etehadnia et al 2008;Liu et al 2007;Rouphael et al 2008) and photosystem II efficiency (PS II) (Ahn et al 1999;He et al 2009;Zheng et al 2009).…”

We examined the hypothesis that leaf gas exchange of scion is affected by different rootstocks in wood plants. We investigated daily courses of gas exchange and photosynthetic potential using the CO 2 assimilation rates as a function of photosynthetic photon flux density, and then assessed CO 2 response curves in atemoya scion (Annona 9 atemoya Mabb.) grafted onto araticum-de-terra-fria [A. emarginata (Schltdl.) H. Rainer var. terra-fria]: ATF, araticummirim [A. emarginata (Schltdl.) H. Rainer var. mirim]: ATM, biribá [A. mucosa (Bail.) H. Rainer]: ATB, atemoya (autograft): ATA, and in ungrafted atemoya plants: CTR. Throughout the entire evaluation period, the net assimilation rate (A net) and stomatal conductance (g s) of CTR plants remained practically constant, being lower than those of grafted plants between 08:00 a.m. and 12:00 a.m., regardless of the rootstock used. Moreover, ATM plants proved to be more efficient in keeping the stomata open, even during the hottest hours of the day, improving A net and carboxylation use efficiency. However, this occurred at the lowest maximum carboxylation rate of ribulose-1,5-bisphosphate (V cmáx). Overall, ATF plants presented a low light saturation point and photosynthetic electron transport rates, though increased maximum quantum yield of photosynthesis was observed. Thus, we accept our hypothesis and conclude that grafting might affect the photosynthetic metabolism of the atemoya hybrid, regardless of the combination used, which promotes enhanced A net and low V cmáx and light saturation points.
