The impact of warming on the phenology of grapevine (Vitis vinifera L.) in conditions of Central Europe was evaluated at the locality of Dolné Plachtince in the Slovakian wine region. In Welschriesling and Pinot Blanc model varieties there was observed onset of phenophases as defined in BBCH scale over 1985–2018 period. Based on the data obtained there was evaluated the influence of average and average maximum temperature and GDD on the onset of phenophases. The results observed indicate earlier budburst by 5–7 days, earlier beginning of flowering by 7–10 days, and earlier berry softening by 18 days, and harvest dates advanced by 8–10 days on average. In both varieties there was found the highest influence of the average monthly temperature in March on budburst, the highest influence of the average monthly temperature and the average maximum temperature in May on the beginning of flowering, and the highest, statistically significant influence of the average maximum temperature in June on grape veraison. The warming observed in moderate climate conditions of northern wine regions in Central Europe (Slovakia) has not caused yet the changes in the grapevine phenology stable enough to require serious adaptation measures.

“…Some cool wine regions that are on the climatic margins of commercial viticulture (like those in Canada (Jones, 2012;Shaw, 2017), the UK (Nesbitt et al, 2016), Hungary (Kovacs et al, 2017), and the Poland-Germany-Czech area (Kryza et al, 2015) may benefit from global warming by becoming suitable for the cultivation of more grape varieties. Conversely, some regions which already have ideal conditions for producing wines (such as in western USA (Jones and Goodrich, 2008;White et al, 2006), Romania (Irimia et al, 2018), Slovenia (Pulko, 2014), and Roussillon in France (Lereboullet et al, 2014) may become too hot to continuously produce high quality wines or maintain existing varieties, or they may be at increased risk of damage by extreme events.…”

The objective of this work was to estimate the influence of climate variability on viticultural zoning and variety regionalisation in China in the past 50 years. A multicriteria climatic indices system, which includes Frost-Free Season (FFS), Dryness Index (DI), and Extreme Low Temperature (ELT), was used to define climatic suitable areas and classify different climate zones for wine grape-growing in China. The Accumulated Effective Temperature (AET) was used as an index of variety regionalisation. Indices were calculated based on daily climatic observations from national ground weather stations throughout China from between 1967 and 2016. The variation trends were analysed by Sen’s slope and Mann-Kendall non-parametric tests in 13 representative wine growing sites. Based on the studied criteria, the suitable viticultural zone exhibited a continuous northward expansion with an average increase of 0.204 million km2/decade, largely due to increasing FFS. A significant increase of FFS was detected in most representative sites, with almost no detectable change of DI during the growing season. The analysis also revealed that the North East Region, Inner Mongolia Region, and Xinjiang Region are the three most profitable wine regions. Movement of the soil-burying line was limited to Shandong and Hebei provinces. Although the suitable viticultural zone increased, the data also revealed a decrease in the area for high quality wine production when considering varietal suitability. These results have important implications for understanding both new opportunities and challenges under changing climate and the latter’s effects on viticultural viability in China. They can also help guide stakeholders to develop adaptive strategies for maintaining the profitability of currently used regions and for developing new regions for viticulture.

In Palatinate wine region occured in the value of the blooming average temperature, growing season average temperature, harvest maximum temperature, and growing season maximum temperature over the past 30 years [23]. Variability of phenological response has been observed not only between distant regions but also over short distances in a wine region which are related to local characteristics [24].…”
