“…This reduces transpiration without any major effect on plant growth or productivity. In the field, PRD has produced positive results in terms of controlling excessive vegetative growth and improving grape quality while contributing to water savings of close to 50% without impairing fruit production [191][192][193][194]. Nevertheless, other studies reported that PRD did not have any considerable effect on grapevine performance when it was compared with the same amount of water applied through conventional drip irrigation [195,196].…”

Water availability is endangering the production, quality, and economic viability of growing wine grapes worldwide. Climate change projections reveal warming and drying trends for the upcoming decades, constraining the sustainability of viticulture. In this context, a great research effort over the last years has been devoted to understanding the effects of water stress on grapevine performance. Moreover, irrigation scheduling and other management practices have been tested in order to alleviate the deleterious effects of water stress on wine production. The current manuscript provides a comprehensive overview of the advances in the research on optimizing water management in vineyards, including the use of novel technologies (modeling, remote sensing). In addition, methods for assessing vine water status are summarized. Moreover, the manuscript will focus on the interactions between grapevine water status and biotic stressors. Finally, future perspectives for research are provided. These include the performance of multifactorial studies accounting for the interrelations between water availability and other stressors, the development of a cost-effective and easy-to-use tool for assessing vine water status, and the study of less-known cultivars under different soil and climate conditions.

“…The wet side delivers enough water to the plant to avoid water stress, while the drying half is linked to the reduction of g s PRD is based on the knowledge that roots produce hormonal and hydraulic signals (as discussed previously) that reduce g s and thereby improves WUE (Gil et al, 2018;Stoll et al, 2000;Tombesi et al, 2018) Many studies compare physiological and qualitative effects of PRD and RD and several excellent reviews summarize the most important results (Chaves et al, 2010;Jovanovic and Stikic, 2018), and conclude that the effects are very similar between both strategies as shown by the meta-analysis of Sadras (2009). Recent deficit irrigation studies of Monastrell grafted on five different rootstocks (140Ru, 1103P, 110R, 161-49 and 41B) in the semiarid winegrowing region of D.O.…”

The increasing risk of water deficit stress due to global warming subjects winegrowers of traditional rain fed viticulture regions to new challenges regarding vine water status assessment and possible drought mitigation strategies, such as irrigation.This review summarizes the most recent studies on the impact of water deficit stress on vine and berry physiology; it discusses the latest scientific advances regarding hormonal and hydraulic regulation and segmentation and addresses the current debate on iso/an-isohydricity within vine cultivars. Latest literature on irrigation frequency, water stress memory and the impact of abiotic factors such as VPD (Vapor Pressure Deficit), radiation, temperature and canopy architecture on vine physiology and water use, raise important questions on water status assessment and the implementation of irrigation strategies. Practical consequences regarding the effects of vine water regime on vine water regulatory mechanisms are discussed. Recent technical and scientific advances shed new light on how site specific irrigation strategies matching production objectives could improve vineyard water use.

“…Hence, there is a direct link between the seasonal weather characteristics, which are mainly temperature expressed in thermal time (degree days) accumulated over 10 • C and phenological stages occurrence and duration [13], berry cell death, wine quality, and aroma profiles [11,12]. Furthermore, these berry quality traits can be manipulated using different irrigation techniques, such as regulated deficit irrigation (RDI) [14][15][16][17][18][19][20] and partial rootzone drying (PRD) [21][22][23][24][25].…”

Wine aroma profiles are determinant for the specific style and quality characteristics of final wines. These are dependent on the seasonality, mainly weather conditions, such as solar exposure and temperatures and water management strategies from veraison to harvest. This paper presents machine learning modeling strategies using weather and water management information from a Pinot noir vineyard from 2008 to 2016 vintages as inputs and aroma profiles from wines from the same vintages assessed using gas chromatography and chemometric analyses of wines as targets. The results showed that artificial neural network (ANN) models rendered the high accuracy in the prediction of aroma profiles (Model 1; R = 0.99) and chemometric wine parameters (Model 2; R = 0.94) with no indication of overfitting. These models could offer powerful tools to winemakers to assess the aroma profiles of wines before winemaking, which could help adjust some techniques to maintain/increase the quality of wines or wine styles that are characteristic of specific vineyards or regions. These models can be modified for different cultivars and regions by including more data from vertical vintages to implement artificial intelligence in winemaking.
