“…Our results indicate a specific clone-rootstock interaction when comparing abiotic stress tolerance (e.g., drought tolerance), water use efficiency, and oenological potential in different cultivars, as it has been previously described [9,10]. It is important to note that large differences in A, g s , and E (vine water use) were observed among Monastrell genotypes (Table 3), which demonstrates that some genotypes present large fluxes of CO 2 and water, and others, low gas exchange fluxes, as observed in clones from other varieties [12,13].…”

“…Of special relevance are the local/traditional varieties/clones, which often outperform modern, widely-planted cultivars and which have led to a growing interest in better understanding, preserving, and exploiting this diversity. Indeed, the diversification of rootstocks and clones as a way of increasing genetic variability, avoiding the cultivation of a single rootstock and clone combination, has been proposed in winegrapes [9], in an effort to explore clone × rootstock interactions when comparing tolerance to abiotic stresses in different cultivars [10]. Exploring grapevine intracultivar variability (e.g., clones) is particularly interesting because there is consistent evidence of significant interclonal variability in water use efficiency at a leaf level (WUE leaf (A/g s )), carbon isotopic discrimination (δ 13 C), stomatal regulation, photosynthetic capacity, and biomass/yield traits [11][12][13][14][15], and, indeed, it respects the cultural and social components of winegrape cultivation and the wine typicity associated with local terroir.…”

Evaluation of the Effect of Water Stress on Clonal Variations of Cv. Monastrell (Vitis vinifera L.) in South-Eastern Spain: Physiology, Nutrition, Yield, Berry, and Wine-Quality Responses

The present study aims to analyze the physiological and agronomical response to drought among seven local and traditional field-grown Monastrell clones (4, 94, 188, 360, 276, 372, and 373) over four seasons (2018–2021) under optimum irrigation conditions (control) and water stress (stress). We have focussed on measuring Monastrell interclonal variability in plant water relations and leaf gas exchange, vegetative growth, leaf mineral nutrition, yield, water use efficiency (WUE), and grape and wine quality. A classification of the different clones according to drought-tolerance degree and agronomical/oenological performance was established. The classification revealed that (a) The most drought-tolerant clone (i.e., clone 4) was neither the most productive (8600 kg ha−1), the most efficient in terms of water use (average of 25 kg m−3), nor the one that presented a better grape quality; (b) The most productive and efficient clone (i.e., clone 94) (11,566 kg ha−1, average of 30 kg m−3) was also a drought-tolerant clone, but it provided the worst berry and wine qualities with the lowest aromatic/nutraceutical potential, and it is not recommended for premium red wine production; (c) Conversely, clone 360 provided the highest berry quality, but at the expense of a greatly reduced vigor and yield (4000 kg ha−1) and a lower WUEyield (average of 10 kg m−3); (d) Low-vigor clones 372 and 276 were the most sensitive to drought conditions and put more water conservation mechanisms into play, i.e., a tighter control of vine water use and reduced leaf transpiratory surface, under soil water deficit and high vapor pressure deficit (VPD). In addition, these clones reached a balance between drought tolerance, productive water use efficiency (WUEyield), and berry and wine quality, because they provided moderate yields (7400–7700 kg ha−1), a high WUEyield (average between 17–19 kg m−3 applied water), and an enhanced berry and wine quality with greater oenological, nutraceutical, and aromatic potential; (e) High-vigor clone 188 also displayed several mechanisms of drought tolerance (tighter stomatal control of water use), maintained a higher yield (10,500 kg ha−1) and a very high WUEyield (29 kg m−3), enhanced berry quality (similarly to 276 or 372), and improved oenological/aromatic potential, and can also be recommended for the application of low water volume deficit irrigation (DI) strategies under semi-arid conditions.

“…Therefore, cover crop floor management strategies, and organic or industrial waste selection should be used as sources of nutrients or soil conditioners for vineyards in the cool humid climate of Eastern Canada [37]. In addition, the importance of both clone and rootstock selection in cool climate regions where freeze injury may occur also have been proposed by some authors [38].…”

(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.

Correlation between dehydrin-like proteins and cold hardiness of grapevine

et al. 2023

Winter survival of Vitis vinifera Linnaeus in cool climate viticultural areas can be jeopardized due to inadequate cold hardiness. Dehydrins are a family of proteins commonly found in plant tissue in response to dehydration stress and cold exposure. To determine their presence and relationship to cold hardiness in overwintering grapevines, compound buds of V. vinifera cv. Sauvignon blanc were sampled from a commercial vineyard every two to three weeks throughout the 2016-2017 winter. Proteins were extracted and separated by SDS-PAGE, and potential dehydrins were immunoblotted with a commercial antibody raised against the dehydrin K-segment consensus sequence. Six protein bands were identified in four Sauvignon blanc clones at 23, 26, 35, 41, 48 and 90 kDa, showing a serological relation to dehydrins due to their reaction with the K-segment antibody. The bands at 23, 41, 48, and 90 kDa were confirmed as dehydrins following trypsin digestion and LC-MS/MS with Mascot analysis. Their fluctuations throughout the dormant season were quantified by immunoblotting and three patterns emerged: the 23, 26 and 35 kDa proteins peaked immediately prior to deacclimation; the 41 and 48 kDa proteins peaked during maximum hardiness and decreased towards deacclimation while the 90 kDa plateaued during the same period. Maximum hardiness and relative dehydrin band intensity were positively correlated (p < 0.050) for all but the 23 kDa protein. The variation in accumulation patterns and relationships to cold hardiness indicates that these dehydrin proteins are likely regulated by different molecular processes and could play different roles in cryo-protection throughout dormancy.
