“…In water-limited areas, the application of deficit irrigation practices can also provide growers with a tool to manipulate fruit composition to enhance and modulate the season-to-season variation in red wine quality attributes (De la Hera et al 2007;Castel 2009, 2010) and to manipulate wine sensory characteristics ). Deficit irrigation, as compared to full irrigation, may also improve berry quality due to an increment in the contents of anthocyanins and total phenols Girona et al 2006;Medrano et al 2003;Santos et al 2005;Sofo et al 2012) even though this response is also cultivar dependent. The effects of regulated deficit irrigation on fruit growth and quality are neutral or positive, while keeping vineyard vigor in balance with potential production (Girona et al 2006;Greven et al 2005;Intrigliolo and Castel 2009).…”

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.

“…This was confirmed in a Spanish trial, in which none of the deficit treatments ranging from −1.1 to −1.2 MPa throughout the season differed from the control in yield and fruit size at harvest, while those reaching values lower than −1.4 MPa from mid-July showed a significant decrease in both parameters [29]. Ψ stem has been successfully used in dominant anisohydric species or cultivars such as fruit trees [30], prune [31,32], apple [33], almond [34] and citrus trees [35], as well as vineyards [36]. However, it has been shown that for species or cultivars with dominant isohydric behaviour, this indicator is replaced by leaf water potential measured at predawn (Ψ pd) [37].…”

-Introduction. The aim of this work was to study the effects of regulated deficit irrigation (RDI) on fruit yield, fruit weight and fruit quality parameters, as well as soil-plant water relations, in apple orchards under highfrequency subsurface drip irrigation in a region with a continental climate. Materials and methods. Four irrigation treatments were applied in 2010 and 2011 to apple trees cv. 'Gala': T1, no irrigation; T2, optimal irrigation except during summer; T3, optimal irrigation except during summer when RDI with a threshold for irrigation at −1.2 MPa midday stem water potential (Ψ stem) was utilised; T4, optimal irrigation. The soil water status and plant water status were followed over two growing seasons. Results and discussion. The irrigation treatments had no significant impact on fruit yield. However, compared with optimal irrigation (T4) and RDI (T3), the absence of irrigation in summer (T1, T2) induced low Ψ stem (< −1.2 MPa), decreased fruit size and slightly increased the soluble solid, vitamin C and polyphenol contents of the fruits. The RDI (T3) during summer allowed a water-use reduction of 47% without loss in fruit yield, fruit weight and fruit quality compared with the optimal irrigation (T4). Conclusion. The RDI treatment saved 47% water compared with optimal irrigation without negative impacts on yield and fruit quality. In the temperate conditions of Switzerland, Ψ stem, as well as Ψ soil, are well adapted for scheduling RDI in apple orchards.Keywords: Switzerland / apple / Malus domestica / irrigation scheduling / regulated deficit irrigation / water stress / phenolics / vitamin C Résumé -Influence de stratégies d'irrigation sur la productivité, la qualité des fruits et le statut hydrique sol-plante de pommiers arrosés en goutte à goutte enterré. Introduction. Le but de cette étude a été d'analyser les effets de la régulation déficitaire de l'irrigation (RDI), avec des applications d'eau en goutte à goutte enterré à fréquence élevée, sur le rendement en fruits, le poids des fruits, et la qualité des fruits, ainsi que sur les relations hydriques entre sol et plante sur des vergers de pommier sous un climat continental. Matériel et méthodes. Quatre procédés d'irrigation ont été appliqués aux pommiers (cv. 'Gala') en 2010 et 2011 : T1, témoin non irrigué ; T2, irrigation optimal à l'exception d'absence d'irrigation durant l'été ; T3, irrigation optimal à l'exception une restriction d'irrigation induisant un stress modéré durant l'été, avec un seuil fixé à -1.2 MPa de Ψ stem (irrigation déficitaire régulée, RDI) ; T4, irrigation optimale. L'impact de ces régimes sur le potentiel hydrique du sol (Ψ soil) et le potentiel hydrique du tronc (Ψ stem) a été suivi pendant deux saisons. Résultats et discussion. Les régimes d'irrigation n'ont eu aucun impact significatif sur le rendement en fruits. Toutefois, par rapport à l'irrigation optimale (T4) et RDI (T3), l'absence d'irrigation en été (T1, T2) induit des potentiels de tronc bas (Ψ stem < -1,2 MPa) et une diminution du poids des ...

“…Recently, the use of regulated deficit irrigation (RDI) has expanded in vineyards to improve (sometimes to reduce) water application, yield per unit water supply, berry composition, and wine quality. The objective of RDI is to apply water deficits of predetermined levels during certain phenological stages when their effects on fruit growth and quality are neutral or positive, while keeping vineyard vigor in balance with potential production (Girona et al 2006(Girona et al , 2009Pellegrino et al 2006;Greven et al 2005). The short and long-term impact of deficit irrigation on production and quality vary with vineyard conditions, namely soil texture and depth, variety, atmospheric environment, and viticultural practices.…”
