Grapevine adaptation to climate change
CLIMAVITIS
Climate change is causing major changes in winemaking changes in winemaking practices at management due to increased temperatures and reduced rainfall. due to increased temperatures and reduced rainfall.
The growth of anthropogenic greenhouse gas emissions has a negative impact on the development of the most widely cultivated grape varieties, on their phenolic composition and, ultimately written request, on wine quality.
General objective
ANTHOCYANIN SYNTHESIS
To evaluate the application of two phyto-regulators, ethephon (ethylene-releasing compound) and abscisic acid (ABA), both easy to handle and apply by grape growers, to stimulate anthocyanin synthesis in grapes and counteract the negative effects that the increase in temperature has on these compounds.
Specific objectives
TREATMENTS
To study whether these treatments affect other grape compounds that determine the sensory quality of the wine produced from grapes (organic acids, flavonols and amino acids, aroma precursors). precursors of aromas).
VINE VARIETY
To evaluate whether the application of these compounds in a simulated global warming scenario is vine variety dependent.
MOLECULAR MARKERS
Identify possible molecular markers that can be used in processes of improvement or selection of grapevine genotypes for adaptation to climate change.
The IPCC (Intergovernmental Panel on Climate Change) forecasts that by 2100:
AtmosphericCO2:
Increase in CO2 atmospheric.
Greenhouse effect:
An increase in temperature due to the greenhouse effect.
Water:
A reduction in water availability in the Mediterranean area .

WHY IS THIS project NECESSARY?
Spain is one of the largest wine producers in the world. With more than 900,000 hectares of vineyards, our country is the world leader in terms of wine-growing area. However, this sector faces great challenges due to climate change and its impact on agriculture. That is why the CLIMAVITIS project aims to address these challenges through research and innovation, providing solutions that help mitigate these effects on grape quality and vine resilience.
WHAT SOLUTIONS DOES THE CLIMAVITIS project STUDY?
CLIMAVITIS studies the application of 2 plant hormones (abscisic acid and ethylene) on the bunch to reduce the impact of high temperatures on the grapes. Both hormones regulate the ripening process and their exogenous application increases anthocyanin levels. The aim is then to observe whether this application allows buffering the negative impact of temperature on these compounds.
how does this project affect society?
Providing tools to help the wine industry meet this challenge allows, on the one hand, to preserve the competitiveness and economic stability of this sector on a global scale and, at the same time, to ensure a quality experience for consumers while keeping the country's wine tradition alive.
