Industry concerns in Australia about the impacts of climate change have, to date, focused on the effects of warming, particularly shorter maturation periods. The effects of elevated CO 2 concentration (eCO 2 ) on C 3 plant physiology have been extensively studied and suggest that eCO 2 impacts on viticulture could affect grapevine shoot growth, fruit production and fruit composition. We previously used open top chambers (OTC) with an active heating system to study the effects of elevated air temperature (eTemp) on mature grapevines in the field. This system was augmented with the ability to elevate atmospheric CO 2 and established in a mature Shiraz vineyard in a factorial combination of eTemp and eCO 2 . Three seasons of observations on the eTemp only treatment corroborated our previous study; all aspects of phenology were advanced, but leaf function was largely unaffected. In contrast, the effects of eCO 2 on phenology were small in the first season, but increased over the subsequent two seasons. Interactive effects of the treatments on gas exchange were observed; photosynthesis rates were significantly higher in the eCO 2 +eTemp treatment, compared to eCO 2 alone, suggesting that the likely future climate will have a larger impact on viticulture than might be predicted from experiments examining only one of these factors.

“…Nonetheless, there is an inherent natural variability in the inter-annual timings of each variety (Tab. 2), which can be mostly attributed to genetic factors and environmental effects, such as climate, soil and viticultural practices [Petrie and Sadras, 2008;Magalhães, 2008;Malheiro et al, 2013]. …”

Monitoring the main grapevine phenological stages is a key procedure for optimizing vineyard activities and improving yield and quality attributes. Remote sensing may be an effective and practical monitoring tool, as data from on-board satellite sensors can measure vegetative growth. In the current study, a 12-year time series of four main phenophases (budburst, flowering, veraison and harvest) were obtained from an experimental vineyard located in Lisbon (Portugal). LANDSAT surface reflectances were used to calculate the Enhanced Vegetation Index (EVI) and derived metrics. Both time series were then analysed. Results show statistically significant relationships between vegetation metrics and phenological timings and intervals, such as the linkage between the peak greenness and flowering/veraison. The current study highlights the applicability of remote sensing to monitor grapevine phenology in both retrospective and real-time, bringing an added-value to the winemaking sector.

Climate change is expected to advance grapevine phenological stages. After the calibration and the validation of a degree-days model, we were able to accurately simulate dates of budbreak, flowering and véraison for Riesling and Gewurztraminer, 2 winegrape varieties grown in Alsace, France. Projected daily temperatures were calculated for the local meteorological station with the ARPEGE-Climat general circulation model using 3 distinct greenhouse gas emissions scenarios. Compared with its timing in 1976-2008, véraison is predicted to advance by up to 23 d and mean temperatures during the 35 d following véraison are projected to increase by more than 7°C by the end of the 21st century for both varieties. Such changes will likely have a significant impact on grape and wine quality. Using the same framework, the genetic variability of phenological parameters was explored with 120 genotypes of progeny from a Riesling × Gewurztraminer cross, along with 14 European varieties. In addition, we created a virtual late ripening genotype, derived from a cross between Riesling and Gewurztraminer. This modelled genotype was projected to undergo véraison 2 to 3 d before Muscat of Alexandria, one of the latest ripening varieties studied. Even with this virtual genotype, or with Muscat of Alexandria, grapes would ripen by the middle of the 21st century under higher temperatures than in the present years. This study highlights the important changes that viticulture will likely face in a future warmer climate and emphasises the need to create very late ripening genotypes or genotypes able to produce high quality wines under elevated temperatures.

The idea that increasing temperatures can lower the quality of grapes and wines is widely accepted (Jackson & Lombard 1993, Jones et al. 2005.Possible responses towards the projected future warming in vineyards include (1) accepting changes in the typicity of wines and altering production accordingly, going as far as producing red wines or dessert wines instead of white wines; (2) adapting varieties in order to maintain a constant typicity; and (3) moving grapevine cultivation to areas that are presently cooler (e.g. higher elevations).Alsace is a white-wine-producing region in northeastern France, and the evolution of phenological stages during the past decades and the consequences for grapevine physiology have been described (Duchêne & Schneider 2005). The next logical steps in this line of study are to assess the future climatic conditions in this region, to evaluate their impact on the currently cultivated varieties and to determine which varieties could be adapted in the future.Three main phenological stages can be used to describe the grapevine developme...
