“…The substantial increase of heat waves, related to the general increase of thermal stress (HHH levels), has several potential negative consequences for plant physiology: damage to photosystems of leaves, berries skin burnt and the phenolic maturity of red cultivars unsuitable for premium quality wines (Teixeira et al ). Bucur and Babeş () studied the frequency of extreme events in Romania, using the thresholds −20, +30 and +35°C for a long period (1977–2015) comparable to the one adopted in this work, and found an increase in frequency for all the thresholds, highlighting the negative effects on quantity and compositional quality of fruit.…”

“…Current research on climate change effects on viticulture in Europe shows: an increase of temperature and the consequent increase of indices that express the thermal resources, such as GDDs, Winkler Index, Huglin Index or other similar indices (Duchêne and Schneider , Orlandini et al , Tomasi et al , Santos et al , Irimia et al , Koch and Oehl , Di Lena et al , Fraga et al ); the shortening of phenological cycles and the advance of phenological timing (Duchêne and Schneider , Tomasi et al , Kartschall et al , Meier et al , Di Lena et al , Fraga et al ); the increase of high temperature stress with negative effects on the quality of production in the warmer areas (Fraga et al ); and substantial stability of frequency of spring frosts with a potential increase in their negative effects due to the early budburst (Kartschall et al , Bucur and Babeş , Meier et al ). …”

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).

“…It is known that the grapevine is particularly sensitive to climate change, so that it can be considered as an indicator plant in this field. In the last decades the impact of climate change was studied on several Romanian wine regions [1][2][3][4][5][6][7]. These studies revealed the effects of climate warming on the evolution of phenological stages [8], on grapevine growth and developement, on grape yield and quality.…”

The climate change influences and trends on the grapevine growing in Southern Romania: A long-term study

The topography and pedoclimatic conditions in Romania are diverse and in many places highly favourable for viticulture. In the past 21 years it was observed that the climate slowly changed, with a visible impact on grape quality. The influence of climate change on grape growing depends however on the vineyard location, relief and soil, multiple combination of varieties and rootstocks, water supply, as well as viticultural practices. The influence of the climate change was studied during a long period of time, between 1998 and 2018, in our experimental vineyard at UASVM Bucharest (N Lat.: 44∘47′07′′; E Long.: 26∘076′28′′; elevation 87 m), located in the Southern part of Romania. The observations made during last twenty one years on qualitative and quantitative parameters of the most widespread Romanian grape variety, Fetească regală grafted on the Kober 5 BB rootstock, along with the calculated values for the usual climatic indices describing viticultural climate, showed some significant climate changes in comparison with a reference period between 1961 and 1997 taken from the existent scientific literature. Our observations during past twenty years reveal a trend of increase in all studied temperature-dependent climatic indices during the grape growing season, with a large variation in the absolute minimum temperatures during winter, which suggests a shift towards an increased thermal amplitude between summer and winter temperatures in certain years. Compared with the reference period (1961–1997), an increase in the following temperature-dependent indices was observed: +0.75 ∘C for the average annual temperature; +0.78 ∘C for average temperature in the growing season; +2.37 ∘C for average maximum temperature in the warmest month; +2.11 ∘C for average maximum temperature in the summer; +234 units in Huglin index; + 173 units in Winkler index and +0.35 ∘C in Cool night index. These climate changes bring important variations of grape yield due to the minimum temperatures during winter and significant reduction of total acidity, along with a significant increase of sugar concentration. This study aids to understand and anticipate the rate of climate change in Southern Romania, the extent of the changes in grape quality and the interventions required to maintain constant grape and wine quality.

“…In spite of all this evidence to which results of some recent studies can be added (Bucur and Dejeu, 2016;Irimia et al, 2017) the impact of climate change on the Romanian viticulture is still little known. Therefore, the aim of this study is to reveal the changes in climatic conditions for wine production in the Romanian wine regions as a result of climate change.…”

“…Some research reveal trends in extreme weather conditions in Romanian viticulture (Bucur and Dejeu, 2016) or shifts in climate suitability for some wine regions (Irimia et al, 2017). This study aims to provide the current IAOe values revealing current climate suitability for the wine production for the 50 most important Romanian wine growing centers, spread all over the Romanian wine growing regions.…”

Horticulture,3, Mihail Sadoveanu Alley, Iaşi, 700490, 2 Romanian Academy, Iaşi Branch, Geography Group,8, Carol I Street, 700505, Iasi, Abstract. The oenoclimate aptitude index (IAOe) reveals climate suitability for wine production in temperate climate conditions. For Romanian wine regions its values were quite stable throughout the years, indicating the possibility of practising certain types of wine production. In the last decades the IAOe values have increased. By using gridded data at 0.1 degrees resolution of temperature, precipitation and sunshine duration for the entire Romanian territory, we calculated the IAOe averages for the 1961-1990 and 1991-2013 periods for 50 wine-growing centers which are representative for the Romanian viticulture. The results indicate that the IAOe mean at Romanian viticulture area level is currently of 4629 units, 270 units higher than the ones between 1961-1990. Due to this increase, the IAOe averages for the wine-growing centers from Moldova, Muntenia, Banat, Crișana and Southern regions have passed during the recent decades to values corresponding to an upper suitability class for wine production. In the winegrowing centers from Transylvania, the IAOe maintains in the range of suitability for white table wines, while for the ones from Dobrogea and Danube Terraces the IAOe maintains in the range of suitability for quality red wines. The study provides the scientific support needed for the re-evaluation of the wine type production practiced within Romanian wine growing-centers.
