“…Clear skies with high solar radiation (PPF = 1000 to 2000 µmol/m 2 s) are common in the summer and fall in southeastern Washington; during the ripening period such days are often coupled with low nighttime temperatures (0 to 15°C). While low temperatures typically accelerate the rate of leaf senescence (Fracheboud et al 2009), they also favor cold acclimation in grapevines (Fennell and Hoover 1991, Ferguson et al 2011, 2014, Schnabel and Wample 1987.…”

“…Once rapid fruit sugar accumulation slows, the plant may change its focus from fruit ripening to replenishment of storage reserves and cold acclimation. Cold acclimation in grapevines is triggered by decreasing photoperiod, which induces bud dormancy, followed by cool temperatures (Fennell and Hoover 1991, Ferguson et al 2014, Schnabel and Wample 1987. This implies that the genetic programs for fruit ripening and cold acclimation must be superimposed and are likely to be regulated independently.…”

This four-year study tested whether the physiological demand of fruit ripening may interfere with grapevine cold acclimation in autumn or with midwinter hardiness. Three harvest time treatments were established in a mature vineyard of own-rooted Cabernet Sauvignon vines: clusters were removed after fruit set, at veraison, or after the first fall frost. Average yield of the late harvested vines varied from 4.2 to 5.1 kg/vine (7.5 to 9.2 t/ha) among years, and soluble solids varied from 23.4 to 25.6 Brix. The presence of fruit during ripening delayed leaf senescence, measured as chlorophyll decline. The fruit also tended to delay the senescence-associated decrease in photosynthesis. All vines showed typical patterns of autumn cold acclimation, midwinter hardiness, and spring deacclimation. Cold hardiness of buds, cane phloem, and cane xylem varied during winter depending on prevailing temperature, and during the coldest winter reached levels of -27°C for 50% bud damage and -28°C for the onset of xylem injury. Early fruit removal had no effect on cane nonstructural carbohydrates and, with few exceptions, failed to enhance cold hardiness. Depending on the year, early fruit removal improved bud hardiness on 5 to 15% and xylem hardiness on 8 to 38% of all measurement dates. On those dates, the early harvested vines tended to be 1 to 2ºC hardier than the late harvested vines, irrespective of the time of crop removal. No trend was found for phloem hardiness. These results indicate that cropping, at least within commercially acceptable limits in regions with sufficiently long or warm growing seasons, rarely impacts cold acclimation and maximum hardiness. Grapevines appear to adjust seasonal leaf physiology to meet their carbon demand for both fruit ripening and cold acclimation.

“…The Riesling plot was not impacted with the same intensity compared to the other studied varieties and their shoots stayed with minimum damage. Dormancy and cold hardiness in Riesling is strongly influenced by photoperiod, temperature, and seasonal carbohydrate changes [31,32]. Ferguson et al [33] showed that Riesling presented the highest bud cold hardiness among the V. vinifera grapevines.…”

(1) Background: Cold-hardy interspecific hybrid grapes (CIHG) are well adapted to the Annapolis Valley edaphoclimatic conditions. The main characteristics of CIHG are the high bud hardiness tolerance to winter frost, the short growing cycle, and the good tolerance to cryptogamic diseases. Based on local experience, the Vitis vinifera varieties should be grown in the warmest areas of the Annapolis Valley (Nova Scotia, Canada). Despite this, there is little scientific evidence that shows the viticultural behavior of these varieties under the edaphoclimatic conditions of this valley. (2) Methods: Thus, the aim of this research was to evaluate the viticultural behavior of two CIHG (L’Acadie and New York Muscat) and three V. vinifera varieties (Chardonnay, Riesling, and Pinot Noir) growing in the Annapolis Valley over three consecutive seasons. (3) Results: The coldest season (2019) produced a delay in grapevine phenology of at least 18 days for budburst compared to the warm seasons (2017 and 2018). In addition, in the coldest season from budburst to bloom the duration decreased compared to the rest of the seasons. The main phenological stages started earlier in L’Acadie than in the V. vinifera varieties. L’Acadie presented lower N petiole content than the V. vinifera varieties, which conditioned shoot growth in the studied seasons. CIHG presented low B petiole levels and produced musts with low malic acid content, while V. vinifera varieties produced musts with high N content. L’Acadie was the only variety that could bud out, and differentially produced fruit after the spring frost of −2 to −3 °C for 2 h in 2018 in this trial. (4) Conclusions: L’Acadie, and to a lesser extent, Riesling, hold an interesting adaptation to the edaphoclimatic conditions of the Annapolis Valley.

“…As a consequence, the steady movement of optimum planting zones towards polar regions and more frequent weather extremes pose significant challenges to food production, particularly to the production of perennial crops such as grapevine, due to high reestablishment cost and slow breeding processes [4][5][6] . Other than an expected migration of vineyards towards cooler regions and a shift to more adaptive cultivars in the future, the grape industry is currently experiencing major crop losses due to climate changeassociated weather extremes such as extreme drought, precipitation, heat and cold [7][8][9][10][11][12] . Among abiotic stresses, cold-related damage in winter and spring is one of the leading constraining factors for the expansion of viticulture into cool and cold climates.…”

It is essential for the survival of grapevines in cool climate viticultural regions that vines properly acclimate in the late fall and early winter and develop freezing tolerance. Climate change-associated abnormities in temperature during the dormant season, including oscillations between extreme cold and prolonged warmth, impacts cold acclimation and threatens the sustainability of the grape and wine industry. We conducted two experiments in controlled environment to investigate the impacts of different temperature regimes on cold acclimation ability in endodormant grapevine buds through a combination of freezing tolerance based physiological and RNA-seq based transcriptomic monitoring. Results show that the freezing tolerance of buds was not altered from field levels when exposed to stable temperatures ranging from 2 °C to 22 °C but was enhanced when exposed to temperature cycling (7±5 °C). We also characterized the transcriptomic response of endodormant buds to high and low temperatures and the potential genetic control for the maintenance of endodormancy. Several pathways that were previously reported to be responsive or functional during cold acclimation, such as theICE-CBF-CORcascade, were not observed to play a role in the enhancement of freezing tolerance or the sensing of different temperatures, indicating our current understanding of the genetic control of cold acclimation remains a challenge when generalizing across plant species and phenological stages.
