“…However, there was no effect on ethyl esters, acetates, volatile fatty acids, and lactones. Recent studies on Verdejo wines reported that concentrations of volatile compounds were increased in non-irrigated vines versus different deficit irrigation regimes (25 % and 50 % ET o ) (Vilanova et al, 2019).…”

Water deficit and iron nutritional deficiency (iron chlorosis) are frequent environmental stresses affecting grapevine production in the Mediterranean region. The objectives of this work were (i) to study the combined effects of both stresses on aromatic profile of Tempranillo grapes, occurring simultaneously in the vineyard, and (ii) to evaluate the viability of foliar chlorophyll content at veraison (Chl) to early assess aromatic quality potential of grapes in those conditions. Twenty non-irrigated vineyard subzones (10 m × 10 m each), affected and non-affected by iron chlorosis, were monitored in Ribera del Duero Appellation of Origin (North-Central Spain) during two consecutive seasons. Factorial ANOVA was performed to study the effects of predawn leaf water potential and Chl measured at veraison on the must composition parameters and, specifically, on the concentrations of free and bound aromatic compounds. Water deficit tended to increase color intensity and extractable anthocyanin content of the grapes, whereas the incidence of iron deficiency enhanced total phenolic compound content within subzones with better water status. More water or iron stressed subzones restricted C 6alcohols contents than less stressed subzones. Without significant effects on vine vigor, yield or berry size, the incidence of iron chlorosis increased the concentrations of some specific terpenes, C 13-norisoprenoids, volatile acids and volatile phenols. These results showed that low to moderate iron stress can have positive effects on grape aromatic quality, and demonstrated that Chl can be a useful tool in precision viticulture to map the aromatic potential within rainfed vineyards affected by iron chlorosis.

“…A number of studies have investigated the effects of water stress or irrigation regimes on vines on grape volatile compounds (Song et al, 2012;Reynolds, 2014, 2017;Talaverano et al, 2017;Vilanova et al, 2019). However, there are currently no field studies on how iron deficiency affects aromatic fractions of grapes.…”

“…Depending on the moment of induction of water stress and its severity, the proportion of skin surface area to mesocarp volume changes [74,97] as does the rate of biosynthesis and degradation of volatile [98] and phenolic compounds [97]. Several authors have reported the effect of vine water status on grape and wine volatile compounds [98][99][100][101][102][103][104][105][106], while Chapman et al [99] showed that water deficit influences berry composition and improves wine sensorial quality, increasing fruity aromas and reducing vegetation aromas.…”

Despite Vitis vinifera L. is a drought-tolerant species-rainfed traditionally grown in a very diversity of climates-irrigation has more and more become a usual practice aimed to obtain regular yields along seasons and to control must composition. Results on vineyard irrigation are dependent on the timing, length and intensity of the water deficit. From budbreak to flowering, shoot growth is very sensitive to water stress, while reproductive growth is almost unaffected. Severe water deficit during fruit set can reduce yield by affecting ovary cell multiplication and expansion. During maturation water stress induces yield reduction by limiting berry growth; along this phase must composition is also affected. There is a positive, linear relationship between must sugar content and available water; however, no relationship has been found to either total acidity or pH. Biosynthesis of anthocyanins and fruity aromas is enhanced by water deficit. Usually, wines from moderate irrigation treatments scored the highest. There is a general agreement that severe, long water deficits diminish must quality, leaf area, fertility and yield, and it has a negative carryover effect on the next seasons by limiting wood reserves to be used the following seasons.

“…This work belongs to a project with two objectives: the first was to determine the impact of water availability on yield components and the must and wine composition from Vitis vinifera L. cv. Verdejo, published in a recent article . The second one was to investigate the influence of crop level in three water regimes on white Verdejo wine volatiles.…”

BACKGROUND: The effects of cluster thinning (TH) on Verdejo wine composition were studied. Cluster thinning was applied in three water regimes (WR) (R0, rainfed control; R25, drip-irrigated at 25% ETo, and R50, drip-irrigated at 50% ETo) during the 2012-2014 seasons.RESULTS: Cluster thinning advanced grape maturity, although this was only significant in 2012. A significant effect of TH on R0 was observed in 2013, the wettest season, increasing the concentration of alcohols, esters, acetates, and lactones. The same trend was shown in 2012 for all groups of volatile compounds in R0. In contrast, for all volatile families to increase was observed in 2014, the driest season, when TH was applied to R50. WR*TH interactions were found in most wine chemical parameters. CONCLUSION: The variation in wine volatile composition among the vintages that were observed shows that the capacity of TH to exert an influence depends not only on the water regime but also on annual conditions.Bold indicates significant differences among treatments. Different letters indicate significant differences for TH in each WR and season for Fisher's test LSD at P < 0.05. * and ns indicate significance at P < 0.05 and not significant, respectively. Semi-quantitative data were obtained as 4-nonanol equivalents.
