“…Hybrids with these species survive much lower winter temperature than V. vinifera cultivars, but they also tend to lose cold hardiness and break bud rapidly in the spring (Kovács et al ). Frost damage is already a major concern for many viticultural regions (Sgubin et al ) and as climate shifts to have more frequent early spring warming events (Ellwood et al , Leolini et al ), hybrid cultivars may ultimately prove problematic and frost sensitive. This study describes the range in variation for supercooling ability and chilling requirement in 43 genotypes of wild grapevine and demonstrates that cold hardiness, while often summarised as a single phenotype, can be separated into several interacting quantitative phenotypes.…”

Background and Aims Grapevine production in cool climates is limited by aspects of winter survival and frost risk. Cold hardiness‐related traits are key to future viticultural sustainability as climate variations, including acute cold events and frost, are predicted to increase even in traditional cultivation regions. This study examines the variation in dormant bud cold hardiness (supercooling) and dormancy (chilling requirement) in 43 different genotypes of the wild grapevine species Vitis riparia, the dominant wild species used to incorporate cold hardiness traits into new hybrid grapevine cultivars. Methods and Results Cold hardiness was evaluated bi‐weekly in 2 years using measures of low temperature exotherms. Whole winter responses were modelled to determine significant factors affecting cold hardiness and determine genotypic differences. Results demonstrate significant differences in supercooling ability and deacclimation rate (loss of cold hardiness) between genotypes. Conclusions This study determined that genotypic differences contribute to initial differences in cold hardiness. However, data modelling suggests that midwinter cold hardiness changes are driven by environment as all Vitis riparia tested in this study respond to temperature in the same manner during the endodormant period of winter. In contrast, responses to warming temperature during ecodormancy are significantly different by genotype. Significance of the Study This study has demonstrated that these two traits interact to determine differences in early versus late winter cold hardiness and help identify breeding germplasm with delayed loss of cold hardiness.

“…The scenarios adopted by most authors suggest further warming of climate, driven by an increase of anthropic forcing (Malheiro et al , Intergovernmental Panel on Climate Change , Leolini et al ). Other authors, however, highlight the role played by natural variability on climate that, for Georgia, is mainly driven by ENSO, NAO and AMO (Mariani and Zavatti , Mariani et al ).…”

“…They observed small shifts in phenology and frost frequency, with a small decrease in frost risk at the warmer area, concurrently with an increase at the cooler site and concluded that shifts in frost risk remained uncertain due to considerable uncertainties of the climate model chains. Again, regarding future climate scenarios, Leolini et al () analysed the variation in phenological timing of grapevine, finding that the future increase of temperature will drive a generalised advance of phenology in Europe. Malheiro et al (), studying the behaviour of several climatic indices for viticultural zoning, concluded that western and central Europe could benefit from a further warming while southern Europe could be affected negatively by higher temperature.…”

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).

“…Viticulture is one of the most important worldwide agricultural practices, with a relevant economic importance in areas where the climate meet requirements for the production of high-quality wines [1]. Grapevine phenological development is modified by abiotic conditions, including the atmospheric temperature, soil water availability, and photoperiod [1,2], and, in addition, genotype-specific characteristics [2]. The weather condition is the main variable affecting grape production for winemaking [3].…”

“…This work seeks to study the flowering stage of four most important autochthonous vine cultivars of the Designation of Origin Ribeiro area and the airborne Vitis vinifera L. pollen concentration in the vineyard in order to achieve the following objectives: (1) To compare the airborne pollen concentration in the vineyard, as collected by two different sampling devices (volumetric and passive sampling), (2) to analyze the influence of the main meteorological variables on plant phenology and pollen concentration, and (3) to test the contribution of the air masses on pollen concentrations in the vineyard area.…”

Phenological, aerobiological, and weather data are useful tools to study local and regional flowering dynamics in crops with economic importance. The present study focuses on four autochthonous grapevine cultivars, namely, ‘Treixadura’, ‘Godello’, ‘Loureira’, and ‘Albariño’ (Vitis vinifera L.), which belong to the Designation of Origin Ribeiro area (located in northwestern Spain) from 2015–2019. The aims of the work were to (1) compare the airborne pollen concentration in the vineyard collected by two different traps, (2) analyze the influence of the main meteorological variables on cultivar phenology and pollen concentration, and (3) test the contribution of the air masses on pollen concentrations in the vineyard. Phenological development has been assessed twice weekly, according to the Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scale. Airborne pollen concentrations were monitored by using two traps during stage 6 (flowering), namely, a Hirst volumetric sampler and a Cour passive trap. The bioclimatic conditions affected the duration of flowering, ranging from 11 and 24 days. The highest seasonal pollen integral (SPIn) was registered in 2016 for the Hirst sampler, with 302 pollen, and in 2019 for the Cour trap, with 1,797,765 pollen/m2/day. The main variables affecting pollen concentrations were average temperature during the main pollen season, as well as, temperatures and dew points during the pre-peak period. The relationship between pollen data registered by both traps and the obtained harvest indicate that the Hirst trap may be more suitable for predicting a local production and that the Cour sampler is more appropriate for forecasting regional productions.
