“…From the end of the chilling phase to budbreak, the model identified base temperatures that ranged between 3.3 and 3.7°C, which were close to the 4°C proposed by Moncur et al (1989) for the earlier phases, although the accumulation period was slightly different in their study. Zapata et al (2017), however, found higher Tb values for Cabernet-Sauvignon (8.4°C) when temperatures were accumulated from January until budbreak. For the period between budbreak and bloom, the base temperature in this study was also found to be lower than those found by Zapata et al (2017) for different red varieties (from 8.2 to 9.6°C).…”

Aim: This research examined relationships between grapevine phenology and climate in the Ribera del Duero DO (Spain). The observed varieties included Tempranillo, the main variety planted in the region, and Cabernet-Sauvignon.Methods and Results: Phenological events for stages C (budbreak), I (bloom), M (véraison) and N (maturity) were analyzed for 2004-2015. Dormant period chilling and late winter heating requirements to initiate growth were evaluated and accumulated temperature (growing degree days-GDD) prior to each phenological event and in between events were examined for the role they play in influencing growth timing. The results were then used to examine future phenological changes due to climate change using eight models integrated in the Coupled Model Intercomparison Project (CMIP5) and for two Representative Concentration Pathways (RCP) scenarios – RCP4.5 and RCP8.5 – for 2030, 2050, and 2070. Accumulated temperatures after March 20th become important for initiating phenology and are strongly correlated to all growth events. The influence of water availability between budbreak and bloom and between bloom and véraison on phenological timing was also confirmed.Conclusions: The projections showed that for the RCP4.5 emission scenario, budbreak is predicted earlier by approximately 2 days for 2030, 3 days for 2050 and 5 days for 2070, while bloom is predicted to be 3 to 8 days earlier and véraison 6 to 19 days earlier for the same time periods. For the RCP8.5 emission scenario, budbreak is modeled to take place about 3 days, 5 days and 9 days earlier, respectively for 2030, 2050 and 2070. Bloom is predicted to occur about 5, 10 and 16 days earlier; véraison is predicted earlier by 10 days for 2030, 19 days for 2050, and 28 days for 2070. Maturity and the timing of harvest could be up to 23 days earlier under the RCP4.5 emission scenario and up to 35 days earlier under the RCP8.5 emission scenario. Compared to Cabernet-Sauvignon, Tempranillo exhibited greater phenological sensitivity to temperature changes in the observed time period that is likely to continue into the future with greater changes to earlier growth events projected. This sensitivity could be problematic for the region due to the variety’s historic importance and points to the need to examine adaptive measures that can help growers to respond to projected changes in climate.Significance and impact of the study: The projected climate changes in the future indicate the potential for significant changes in the phenology of Tempranillo in the Ribera del Duero DO, Spain. Given that this variety has the largest contribution and importance in this region, these changes could have impacts on wine quality, indicating the need of establishing strategies to reduce or mitigate the impact from future changes in climate.

“…The most noteworthy results were the low DOY and high GDD 50 recorded for budbreak in 2012 compared with the other 3 years (Table 4), results that were affected by the early spring warming that year. These results are inconsistent with the common theory that heat accumulation (GDD 50) is more accurate for predicting annual phenology than is calendar date (Garc ıa de Cort azar- Atauri et al, 2009;Zapata et al, 2017). Common theory would expect that the DOY of budbreak would have been early during 2012 (which it was), but it also would expect that the GDD 50 should have been more consistent across the 4 years (which it was not).…”

“…ASSESSMENT OF GDD 50 INDEX. Along with the use of heat unit summation for comparing growing regions, cultivars, and/or growing seasons, it is often suggested that tracking of heat units during a season can be a useful way to predict the arrival of important developmental stages for grapes and other fruit crops, and GDD 50 is most often the index of choice for calculating heat units for grapes (Garc ıa de Cort azar- Atauri et al, 2009;Gentilucci and Burt, 2018;Verdugo-V asquez et al, 2017;Washington State University, 2016;Zapata et al, 2017). Our results with northern hybrid grapes over seven growing seasons indicate that GDD 50 is useful for comparing seasons and cultivars, but its accuracy as a stand-alone index for predicting annual phenology in midwestern U.S. climates is poor.…”

The popularity of grape (Vitis sp.) and wine production in the upper midwest region of the United States is increasing steadily. The development of several coldclimate, interspecific-hybrid grape cultivars (northern hybrids) since the 1980s has improved the probability of success for both new and established vineyards in this area of the country, but long-term data describing the performance of these cultivars in midwestern U.S. climates are needed to both aid growers in their choice of cultivars and to provide them with information about factors important in their management. We characterized the long-term winterhardiness and annual phenology of 12 cold-climate northern hybrid grape cultivars (two established cultivars, five newer cultivars, and five advanced selections) grown in a randomized and replicated field plot in central Iowa, an area that offers a warm growing season and very cold dormant season for grape culture. The established cultivars included in the study were Frontenac and St. Croix. The newer cultivars evaluated were Arandell, Corot noir, La Crescent, Marquette, and Petit Ami, and the advanced selections were MN 1189, MN 1200, MN 1220, MN 1235, and MN 1258. The grape trial was established in 2008, and vines were evaluated from 2011 through 2017 for annual timing of budbreak, bloom, veraison, and harvest, as well as winter survival of vines and primary buds. As a group, the northern hybrids in our trial showed good winterhardiness of vines but variable hardiness of primary buds across the six winters, which ranged from warmer than average to much colder than average. In Iowa climate, buds of northern hybrids were generally most vulnerable to cold temperature damage from late-winter (March) low-temperature events or from extreme midwinter low-temperature events. The bud hardiness of individual cultivars ranged from very hardy (Frontenac, Marquette, and MN 1235) to poor hardiness (Arandell, Corot noir, Petit Ami, and MN 1189), with all 12 cultivars showing good bud survival during Iowa winters that were warmer than average, but the less-hardy cultivars showing poor bud survival during winters that were colder than average. Evaluations of phenology revealed that heat accumulation measured in growing degree days with a threshold of 50°F was not a reliable index for predicting the timing of annual developmental stages for the cultivars we tested. Our results indicate that northern hybrids rely on other factors in addition to heat accumulation for guiding annual development, and that factors such as photoperiod likely have a strong influence on phenological timing during seasons with unusual weather patterns. We determined that none of the cultivars were vulnerable to cold temperature damage to fruit before harvest in Iowa's climate, but that three of the cultivars (Arandell, Marquette, and MN 1235) were highly vulnerable to shoot damage from spring freeze events, and four others (Corot noir, La Crescent, MN 1200, and MN 1220) were moderately vulnerable to cold damage to shoots in spring.

“…Sadras and Petrie () used GDD Sep–Mar in their study for the relatively warmer Australian regions, so for these reasons, this updated version of the GDD index was adopted in this study. One criticism of the GDD calculation is the use of 10°C as the base temperature (Moncur et al , Nendel , Parker et al , Zapata et al ); research by Pouget () demonstrated a range of 4.3–11°C for the growth threshold for different grape cultivars. As most researchers have continued to use the 10°C base temperature, for comparative purposes, it has been accepted in this study.…”

Background and Aims: As grapegrowers move to adapt to climate change, they need more detailed information on what cultivars to plant and where to plant them. The aims of this study were to understand how different cultivars in different regions are responding to changes in climate, in order to inform future cultivar selections. Methods and Results: Trends in the day of year maturity (DOYM) between 1999 and 2018 were analysed for 23 grape cultivars (covering at least 7 years) and four Victorian vineyard regions against vintage year, seasonal growing degree day (GDD Sep-Mar ) and Spring Index. In most cases there were significant trends in DOYM advancement as a function of GDD Sep-Mar and spring index. Temporal advancement of DOYM was more variable. One cultivar showed a significant advancement at two of three sites and another showed a significant delay. Different cultivars advanced DOYM at significantly different rates at a given site, later ripening cultivars advanced DOYM faster than earlier ripening cultivars and for a cultivar grown across several sites, the DOYM advancement was faster at cooler sites. Conclusions: Grapevine cultivars respond to warming temperature differently and the advancement of grape maturity is predicted to slow as temperature further increases. Significance of the Study: The study showed diversity in the phenological response of cultivars to temperature, which may be utilised to better adapt to climate change.
