“…In Baja California and California, the number of suitable years may decline by 30%-50%, indicating an increase in the uncertainty from year to year. This is consistent with several studies (Droulia & Charalampopoulos, 2021;Firth et al, 2017;Hannah et al, 2013;Jones, 2007;Mesterh azy et al, 2014;Monteverde & De Sales, 2020;White et al, 2006) that also suggest significant reductions in the winegrowing areas of the United States (especially California) and other regions of the world.…”

“…Furthermore, in Baja California the GDDs could shift from 1878 during the historical period to 2126 in the NF, still within suitable conditions. These scenarios are like those of Monteverde and De Sales (2020) for southern California who used a single regional climate model (WRF‐SSIB) to investigate winegrape suitability during the mid‐21st century. These future GDDs fall within the limits of regions where varieties with higher sugar content and low acidity can be grown, such as Chardonnay, Cabernet Franc, Merlot, Colombard, Mission, Nebbiolo, Palomino and Carignane (Jones et al, 2005; Winkler et al, 1974) which produce red and white table and dessert wines.…”

We analysed the current climate of seven winegrowing regions of Mexico and their possible changes during the 21st century. Various bioclimatic indices were calculated with observations and simulations over a wide domain that covers Mexico and the south and southwest United States. We used two regional climate models (RegCM4.7 and RCA4) for historical (1981–2010), near future (NF: 2021–2050) and far future (FF: 2070–2099) periods under two greenhouse gas emissions scenarios (RCP2.6 and RCP8.5). Both models reproduced the main characteristics of the Mediterranean and semiarid climates typical of the winegrape regions with some biases. Despite the errors, the models suggest similar future changes during the growing season (GS: April–October) in winegrape regions. Increases in temperature (~1.2°C) are expected in the NF, which could produce an early start from the growth (mid‐March) season to the harvest. More significant changes are expected in the FF under the RCP8.5 scenario; temperature during April–October may increase ~4°C, and growing degree‐days (GDD) and minimum temperature could also increase (~700 and 4.5°C, respectively), especially in the northern Mexican high plateau, substantially reducing the suitable areas for viticulture. In Baja California (BC) the suitable years for viticulture may decline by 30%–50%, suggesting an increase in the interannual uncertainty. Moreover, in BC and California the number of cool nights (Tmin < 12°C) could be reduced during the current harvest season (September) affecting winegrape acidity and flavour. Therefore, the viticulture sector and the wine industry may need to implement early adaptation/mitigation measures to overcome these possible changes and winegrape phenology shifts.

“…Likewise, weather data recorded during 2020 growing season in Oakville, CA, United States ( Figure 1 ), suggested more stressful conditions for grapevines comparing to the average of last 20 years, challenging their production and quality. Indeed, a recent study based on climate indices suggested a reduction of 8,700 km 2 for the California land suitable for grapevine cultivation by mid-21st century ( Monteverde and De Sales, 2020 ). Within this scenario, smart-farming techniques are mandatory for adaptation and mitigation to guarantee the future of the winemaking industry and for reducing potential water conservation issues.…”

Arbuscular Mycrorrhizal Fungi Inoculation and Applied Water Amounts Modulate the Response of Young Grapevines to Mild Water Stress in a Hyper-Arid Season

Several factors may affect the success of a replanting vineyard. Given the current environmental conditions, an optimized irrigation schedule would still be one of the most desirable tools to improve crop productivity and fruit quality. On the other hand, the symbiosis of grapevines with arbuscular mycorrhizal fungi (AMF) is a key component of the vineyard production systems improving the vine growth, nutrient uptake, and berry quality. The aim of this study was to characterize the response of Merlot grapevines to AMF inoculation and two different irrigation amounts in their first productive year. The experiment was conducted on 2-year Merlot grapevines inoculated with AMF (I) or not-inoculated (NI) and subjected to two irrigation amounts, full irrigated (FI), where the amount of water was enough to maintain expansive growth and half irrigated (HI) where plants received the half of the amount of water of FI plants. Water status, gas exchange parameters, growth, mineral content, berry composition, and mycorrhizal colonization were monitored through the season. AMF inoculation improved the grapevine vegetative growth, water status, and photosynthetic activity, especially when vines were subjected to HI irrigation; however, no effect was observed on the leaf mineral content, must pH, total soluble solids, or total acidity. The main effects were observed on the flavonoid composition of berry skins at harvest. Irrigation amounts and mycorrhizal inoculation modified cyanidin and peonidin derivatives whereas flavonol composition was mainly affected by irrigation treatments. A strong relationship between the mycorrhizal colonization rate of roots and total quercetins, cyanidins, and peonidins was found. Findings support the use of a mycorrhizal inoculum and a better water management in a hyper-arid growing season; however, these results may be affected by edaphoclimatic characteristics and living microbiota in vineyard soils, which should be taken into account before making the decision of inoculating the vineyard.

“…Once chill requirements are satisfied, crops respond to warm temperatures to progress through bud break, flowering, and fruit maturity. Sufficient warmth through this growing period is needed for the crop to successfully reach maturity with different crops and cultivars needing varying growth promoting temperatures (Monteverde & de Sales, 2020; van Leeuwen et al, 2019).…”
