Assessment of plant water consumption rates under climate change conditions through an automated modular platform

Abstract

The impact of climate change is noticeable in the present weather, making water scarcity the most immediate mediator reducing the performance and viability of crops, including grapevine (Vitis vinifera L.). The present study developed a system (hardware, firmware, and software) for the determination of plant water use through changes in weight through a period. The aim is to measure the differences in grapevine water consumption in response to climate change (+4oC and 700 ppm) under controlled conditions. The results reveal a correlation between daily plant consumption rates and reference evapotranspiration (ETo). However, plant water consumption had much strongercorrelations with leaf area and substrate available water content. Interestingly, an increase in 4oC and 700 ppm of CO2 did not result in higher water consumption rates when plants had similar leaf areas. This is supported by the lack of differences in discrete leaf transpiration (E) rates determined throughout the same period. Stomatal conductance was significantly lower in +4oC and 700 ppm plants, which agrees with the reported effect of CO2 in previous studies. Although further investigation will be carried out to determine the impact of each of the climate change factors on daily water consumption rates, photosynthetic acclimation to elevated CO2 may be a key factor for the adaptation of crops to water scarcity.

The generation of suspended cell wall material may limit the effect of ultrasound in some varieties

The disruptive effect exerted by high-power ultrasound (US) on plant cell walls, natural barriers to the diffusion of compounds of interest during the maceration of red wines, is established as the reason behind the chromatic improvement that its treatment causes. However, sometimes this improvement is not observed, especially with short maceration times. The presence of a high quantity of suspended cell wall material, which formation is favored by the sonication, could be the cause of this lack of positive results since this cell wall material has a high affinity for phenolic compounds.

Reduction of the height of the canopy in fruit set and in pea size: vegetative, productive and maturation effects, in cv. Verdejo

Global warming is accelerating the technological ripening of the grape, with a loss of acidity, which requires that vineyard management can delay ripening to avoid it. The source-sink relation is essential for grape ripening, since it affects the distribution of photosynthates and substances derived from plant metabolism. A work is proposed to know the response of the vineyard to the drastic reduction of the foliar surface by trim down the shoots in cv.

Performance of Selected Uruguayan Native Yeasts for Tannat Wine Production at Pilot Scale

The wine industry is increasing the demand for indigenous yeasts adapted to the terroir to produce unique wines that reflect the distinctive characteristics of each region. In our group, we have identified and characterized 60 native yeast strains isolated from a vineyard in Maldonado-Uruguay, in which three strains stood out: Saccharomyces cerevisiae T193FS, Saturnispora diversa T191FS, and Starmerella bacillaris T193MS. Their oenological potential was evaluated at a semi-pilot scale in Tannat must vinification in the wine cellar to have a more precise and representative evaluation of the final product.

Using climate services to project grapevine varietal adequation under climate change – application to cv. Tempranillo in the Douro wine region

Vine growth circumstances are becoming warmer and drier because of climate change. Higher temperatures advance ripening to a point in the season less conducive to the production of fine wine, while drought reduces yields (Van Leeuwen et al., 2019). Several wine-producing regions around the world have already recognized threats to their viticultural viability (Santos et al., 2020). An economical and cost-effective strategy for adaptation is the employment of late-ripening, drought-resistant plant material (varieties, clones, and rootstocks).
