“…C 13 -norisoprenoids such as β-damascenone and β-ionone, contribute to the varietal aroma of many grape varieties due to their extremely low olfactory perception thresholds (0.05 and 0.09 μg/L, respectively, Table 4) [34]. In this study, the concentrations of C 13 -norisoprenoids in grape musts ranged from 4.7 μg/L in Frontenac gris to 24.0 μg/L in St. Pepin, with the main compounds being β-damascenone and α-ionol ( Table 2).…”

“…In Quebec, a few studies focused on the impact of different agricultural practices on parameters such as cold tolerance [13], disease susceptibility [14], maturity and fruit quality [15], but most studies focused on agronomic aspects rather than wine production. Yet knowledge of the volatile compounds of Vitis varieties is crucial for optimizing the quality of wines.…”

Viticulture and wine production in challenging environments such as cold and humid areas has substantially expanded in recent years, mostly due to the development of grapevine varieties that show high resistance to fungal diseases and cold temperatures. These interspecific hybrid Vitis (IHV) varieties result from multiple crosses between Vitis vinifera varieties and North American native species such as V. riparia and V. labrusca. Limited scientific information is available on the aroma and winemaking of IHV, and about the relationships between grape and wine composition in regard to compounds of enological interest. In this work, the profile of volatile compounds of grapes and wines from five white IHV varieties largely grown in cold-climate viticulture (Frontenac blanc, Frontenac gris, Seyval, St. Pepin and Vidal) was determined by GC-MS-SPME. Compound classes detected in juice and wine included fatty acid degradation products that represented the largest part of volatile compounds, fatty acid ethyl esters, terpenes, C 13 -norisoprenoids, and volatile phenols and other phenyl derivatives. The flavor profile of Vidal showed the largest diversity of compounds in both juice and wine, and the overall highest amount of volatile compounds of all varieties. Principal component analysis showed relationships between the presence of certain C 6 compounds, terpene and volatile phenols in musts and in the finished wines.

“…Other major considerations for producers going forward include the need for evaluation of different trellis and training systems, which may offer greater winter protection potential than a standard single high-wire bilateral cordon trellis-training system. Likewise, supplemental winter protection may be necessary via soil/snow burial, or through use of geotextile fabrics, if consistent production of non-adapted genotypes is desirable for producers [33,34]. Training systems worth considering include fan, dragon, crawled cordon, low cordon, mini-J, or head pruning near the soil-surface to facilitate burial or supplemental protection of fruiting wood against dangerous winter temperatures [13,35,36].…”

Cold-Hardy Grape Cultivar Winter Injury and Trunk Re-Establishment Following Severe Weather Events in North Dakota

et al. 2020

View full text Add to dashboard Cite

Extreme winter temperatures during the 2018–2019 dormant season contributed to trunk collapse and complete trunk death of numerous genotypes throughout a diverse grapevine planting in eastern North Dakota, USA. Through the early portion of the dormant season, 12 genotypes were screened to identify lethal temperature exotherms of primary buds; from these results, none were anticipated to be fully prepared to survive the −37 °C minimum temperature recorded in the region. Trunk collapse, death, and survival were monitored for 35 replicated genotypes. New trunks were retrained from suckers and monitored for growth following trunk removal. Only five genotypes exceeded 50% trunk survival at the end of the 2019 growing season, ‘Valiant’, ‘King of the North’, ‘John Viola’, ‘Baltica’, and ‘Bluebell’. Following re-establishment, ‘La Crescent’ was the most vigorous genotype with the largest sucker circumference, sucker length, and internode length. Nearly all genotypes evaluated produced suckers with lengths approaching the high-wire trellis height (1.8 m), designating their potential for cordon retraining in 2020. Cumulatively, however, the lethal temperature exotherm results and the trunk survival examination indicate a harrowing need for investigation of new management practices (such as protected training systems) and the generation of new cold-hardy genotypes to enhance productivity under standard unprotected systems.

“…A potentially useful technique, especially for grafted vines, is placing bails of straw, closed-cell polyethylene sheeting (Bordelon, 1996), or geotextile fabric (Khanizadeh et al, 2005) around the vines in late fall. Some of their beneficial effects result from favoring the collection of an insulating layer of snow.…”
