“…Specific thresholds of NHH accumulation were defined to describe the development of the international cultivars Cabernet Sauvignon and Chardonnay (Mariani et al ), the Italian cultivar Barbera (Cola et al ) and four Georgian cultivars Mtsvane Kakhuri, Rkatsiteli, Ojaleshi and Saperavi (Cola et al ). The positive performance showed by all the models confirmed the goodness of the parameterisation, and the parameters were assumed to be representative of grapevine growth, irrespective of the cultivar.…”

“…This model was used to describe the phenological development of cypress, olive, black elder (Mariani et al ), tomato (Bulgari et al ), wheat, barley, maize and sorghum (Cola et al ). The same model was calibrated for grapevine cultivars Cabernet Sauvignon, Chardonnay (Mariani et al ), Barbera (Cola et al ) and four Georgian cultivars (Mtsvane Kakhuri, Rkatsiteli, Ojaleshi and Saperavi) (Cola et al ). Furthermore, NHHs were also used for a comprehensive analysis of the effects of climate change on the distribution of European crops, grapevine included.…”

Background and Aims The growth and development of grapevine is constrained by temperature, affecting the bulk of physiological processes of the plant. The aim of this study was to evaluate the effects of climate change on thermal resources and limitations in the context of Georgia, one of the oldest viticultural areas in the world. Methods and Results The analysis on daily series of temperature for the time period 1974–2013 for the main viticultural areas of Georgia shows that an abrupt change to warmer temperature occurred in 1994, leading to a decline in low temperature stress and an increase in high temperature stress, associated with more frequent heat waves. The availability of thermal resources for grapevine growth remained unchanged. Conclusions In Georgia, the shift to warmer temperature did not affect the availability of thermal resources for grapegrowing. Although some attention should be paid to possible damage due to an earlier budburst and increased frost risk. Furthermore, it is important to highlight the strong increase of summer heatwaves with potential negative impacts on grape composition and phenolic maturity, when combined with severe water stress. Significance of the Study Quantitative studies of the effects of climate change on Georgian viticulture are essential to develop adaptation strategies based on either germplasm (e.g. rootstocks and cultivars) and agronomical practices (e.g. pruning, trellis systems, soil and water management).

“…A large diversity of PBMs exists in grape literature (see for review Dai et al, 2010 ;Moriondo et al, 2015), developed at different time and spatial scales, ranging from crop models, which aim at simulating the entire plant growth cycle (e.g. Bindi et al, 1996;Garcia de Cortazar-Atauri et al, 2006), to functional models, which focus more on specific processes such as phenology (Cola et al, 2014;Garcia de Cortazar-Atauri et al, 2009 ;Parker et al, 2011Parker et al, , 2013, leaf gas exchanges (Prieto et al, 2012), plant water dynamics (Lebon et al, 2003), or berry growth and quality (Dai et al, 2008 ; Figure 1). The choice of which processes to represent in detail and the level of complexity achieved for a given process is of course conditioned by the understanding of underlying grapevine physiology and the available experimental dataset.…”

Designing genotypes with acceptable performance under warmer or drier environments is essential for sustainable crop production in view of climate change. However, this objective is not trivial for grapevine since traits targeted for genetic improvement are complex and result from many interactions and trade-off between various physiological and molecular processes that are controlled by many environmental conditions. Integrative tools can help to understand and unravel these Genotype × Environment interactions. Indeed, models integrating physiological processes and their genetic control have been shown to provide a relevant framework for analyzing genetic diversity of complex traits and enhancing progress in plant breeding for various environments. Here we provide an overview of the work conducted by the French LACCAVE research consortium on this topic. Modeling abiotic stress tolerance and fruit quality in grapevine is a challenging issue, but it will provide the first step to design and test in silico plants better adapted to future issues of viticulture.
