“…There is the need to use more integrated measurements as stable carbon isotope composition (δ 13 C) De Souza et al 2003, 2005Romero et al 2014;Santesteban et al 2011). In general, differences between irrigation strategies have been found when the amount of water applied was different Santesteban et al 2011). For some experiments, some differences have been found between partial root zone drying and regulated deficit irrigation with the same amount of irrigation (Romero et al 2014) being δ 13 C as a good proxy of integrated WUEc throughout the season.…”

“…One of these strategies as discussed before is regulated deficit irrigation, which has been explored to control vegetative growth (Edwards and Clingeleffer 2013; Greven et al 2005;Intrigliolo and Castel 2010;Santesteban et al 2011;Tarara et al 2011;Terry and Kurtural 2011). This technique improves vigor by reducing water application and yield per unit water supply (Acevedo-Opazo et al 2010;Edwards and Clingeleffer 2013;Myburgh 2003;Tarara et al 2011).…”

Water is critical for viticulture sustainability since grape production, quality and economic viability are largely dependent on water availability. The total water consumption of vineyards, 300 to 700 mm, is generally higher than the annual average precipitation in many viticultural areas, which induces a risk for sustainability of vineyards. Improving vineyard water use efficiency (WUE) is therefore crucial for a sustainable viticulture industry in semi-arid regions. Increased sustainability of water resources for vineyards can be achieved using both agronomical technology and cultivar selection. Here, we review advances in grapevine water use efficiency related to changes in agronomical practices and genetic improvements. Agronomical practices focus on increasing green water use by increasing soil water storage capacity, reducing direct soil water loss, or limiting early transpiration losses. Cover crops for semi-arid areas show a favorable effect, but careful management is needed to avoid excessive water consumption by the cover crop. Canopy management practices to reduce excessive water use are also analyzed. This is a genetic based review focused on identifying cultivars with higher WUE.

“…A strategy of deficit irrigation (DI) has been often adopted for vines aiming to obtain high quality grapes for wine production [1,2]. An adequate management of DI depends upon an accurate control of the crop water status, which is often done through measurements of predawn leaf water potential (Ψpd).…”

Several vegetation indices (VI) derived from handheld spectroradiometer reflectance data in the visible spectral region were tested for modelling grapevine water status estimated by the predawn leaf water potential (Ψpd). The experimental trial was carried out in a vineyard in Douro wine region, Portugal. A statistical approach was used to evaluate which VI and which combination of wavelengths per VI allows the best correlation between VIs and Ψpd. A linear regression was defined using a parameterization dataset. The correlation analysis between Ψpd and the VIs computed with the standard formulation showed relatively poor results, with values for squared Pearson correlation coefficient (r 2 ) smaller than 0.67. However, the results of r 2 highly improved for all VIs when computed with the selected best combination of wavelengths (optimal VIs). The optimal Visible Atmospherically Resistant Index (VARI) and Normalized Difference Greenness Vegetation Index (NDGI) showed the higher r 2 and stability index results. The equations obtained through the regression between measured Ψpd (Ψpd_obs) and optimal VARI and between Ψpd_obs and optimal NDGI when using the parameterization dataset were adopted for predicting Ψpd using a testing dataset. The comparison of Ψpd_obs with Ψpd predicted based on VARI led to R 2 = 0.79 and a regression coefficient b = 0.96. Similar R 2 was achieved for the prediction based on NDGI, but b was smaller (b = 0.93). Results obtained allow the future use of optimal VARI and NDGI for estimating Ψpd, supporting vineyards irrigation management.

“…Vineyard irrigation practices such as regulated deficit irrigation (RDI), where water application is restricted below the full evapotranspiration (ET c ) of a vineyard, can alter the biosynthesis of anthocyanins and tannins, impacting the chemical and sensory composition of the wines (Casassa et al 2013d(Casassa et al , 2015. The chemical and sensory effects of different RDI protocols have been reported (Santesteban et al 2011, Shellie 2014, Casassa et al 2015. However, it is not known how differences in fruit chemistries arising from RDI interact, and if so, to what extent with regard to specific winemaking techniques.…”

Four methods of regulated deficit irrigation (RDI), an irrigation technique whereby water is supplied at rates at or below the full evapotranspiration (ET c ), were applied to Cabernet Sauvignon grapes. The grapes were thereafter processed with three winemaking techniques: control (10-day maceration), extended maceration (EM; 30-day maceration), and saignée (removal of 16% of must by volume at crushing). The 25% ET c treatment had higher concentrations (fresh weight basis) of skin anthocyanins and seed tannins. Overall, skin tannins showed increased biosynthesis in 100% ET c and 25/100% ET c , whereas seed tannins were mostly (positively) affected due to a reduction of fresh weight in 25% ET c . Extraction of anthocyanins and tannins during winemaking ranged from 40 to 73% and from 17 to 26%, respectively. During maceration, the extraction curves for both anthocyanins and tannins were unaffected by the RDI treatments; quantitative differences were caused primarily by the winemaking treatments and secondarily by the RDI treatments. Consistent with a higher content of anthocyanins, 25% ET c wines had higher concentrations of polymeric pigments and greater color saturation and a* (red color component) both at day 30 and after 120 days post-crushing. EM enhanced seed tannin extraction, which resulted in a 50% increase in wine tannins relative to control and saignée wines, but it lowered anthocyanins and color saturation. Saignée increased anthocyanins at day 5 by 22% and tannins by 24% (relative to control wines), resulting in higher concentrations of polymeric pigments after 120 days. Both saignée and control wines had a roughly equivalent proportion of seed-and skin-derived tannins, whereas EM wines had 73% seed-derived tannins.
