“…These results are consistent with the Mediterranean climate of the study zone that Schultz (2017) characterized as a waterlimited region. According to Schultz (2017), during the summer period, water constraints appear progressively because the evaporative demand largely exceeds precipitation. These results were also consistent with other research that have studied the shoot growth stop when the vine is exposed to water restriction, in both experimental (Pellegrino et al 2005) and real conditions (Martinez-De-Toda et al 2010) The results here also indicated that the shoot growth stop was earlier in the 2020 season.…”

Monitoring vine water status is a major issue for vineyard management because water constraints impact both the quality and the quantity of the harvest. Existing methods are often costly and complex to implement. ApeX-Vigne is a free mobile application developed to facilitate the collection and geolocation of 50 vine apex observations to characterise vine shoot growth and classify it into 3 growth categories. The application also provides the user with a simple estimate of vine water status based on shoot growth. This paper presents the results obtained over two seasons (2019 and 2020) after the launch of the Apex-Vigne application and its use over a large wine producing region in the south of France. An existing method was adapted for evaluating the interest of the application based on the number of installations and uninstallations. The results showed that the application had more than 1200 downloads and 6000 observations made in the 2020 season. Examples from the commercially collected data showed that ApeX-Vigne can be used as a tool for characterizing water stress at within-field and inter-field scales. Finally, it was also demonstrated that by enabling the massive and centralized collection of spatial field and within-field scale observations of shoot growth, the ApeX-Vigne data was able to characterise the spatial structure of vine water status at the regional scale. Access to this new source of information offers opportunities for the management of water resources at a regional scale as well as for site-and vineyard-specific management. These results also raised new research questions on the joint use of this new source of spatial data with other sources of high spatial resolution information.

“…Climate changes may have dramatic effects on viticulture and wine industry, maintenance of landscape, and promotion of tourism (Hannah et al 2013). However, the predicted changes of climate are region-specific and adaptation can only be successful considering the regional characteristics with its diverse technical, environmental, economic, and social implications (Schultz 2017). Predicting precisely the impact of climate change on viticulture is difficult for several reasons (a) there are uncertainties on the outputs of the predictive models; (b) models should be adapted to viticulture and should be considered on a small scale (plot or terroir) rather than on a regional scale, because microclimate (altitude, slope, orientation of the vine rows) and soil heterogeneity significantly change the scenario predicted at the larger scale (Quénol et al 2017).…”

“…The evolution of the atmospheric water demand is a matter of debate. Using formulas such as Penman-Montheith's, evapotranspiration (ET) are supposed to increase together with temperatures but trends for decrease in pan evaporation were also reported (Roderick et al 2009;Schultz 2017). The opinion that water deficit will increase in the future is nevertheless widely shared.…”

Molecular Tools for Adapting Viticulture to Climate Change

Adaptation of viticulture to climate change includes exploration of new geographical areas, new training systems, new management practices, or new varieties, both for rootstocks and scions. Molecular tools can be defined as molecular approaches used to study DNAs, RNAs, and proteins in all living organisms. We present here the current knowledge about molecular tools and their potential usefulness in three aspects of grapevine adaptation to the ongoing climate change. (i) Molecular tools for understanding grapevine response to environmental stresses. A fine description of the regulation of gene expression is a powerful tool to understand the physiological mechanisms set up by the grapevine to respond to abiotic stress such as high temperatures or drought. The current knowledge on gene expression is continuously evolving with increasing evidence of the role of alternative splicing, small RNAs, long non-coding RNAs, DNA methylation, or chromatin activity. (ii) Genetics and genomics of grapevine stress tolerance. The description of the grapevine genome is more and more precise. The genetic variations among genotypes are now revealed with new technologies with the sequencing of very long DNA molecules. High throughput technologies for DNA sequencing also allow now the genetic characterization at the same time of hundreds of genotypes for thousands of points in the genome, which provides unprecedented datasets for genotype-phenotype associations studies. We review the current knowledge on the genetic determinism of traits for the adaptation to climate change. We focus on quantitative trait loci and molecular markers available for developmental stages, tolerance to water stress/water use efficiency, sugar content, acidity, and secondary metabolism of the berries. (iii) Controlling the genome and its expression to allow breeding of better-adapted genotypes. High-density DNA genotyping can be used to select genotypes with specific interesting alleles but genomic selection is also a powerful method able to take into account the genetic information along the whole genome to predict a phenotype. Modern technologies are also able to generate mutations that are possibly interesting for generating new phenotypes but the most promising one is the direct editing of the genome at a precise location.
