biostudies-literatureUnknown13Wohlfahrt YAtmospheric carbon dioxide (CO₂) concentration has continuously increased since pre-industrial times and has currently reached an average growth rate of 2.3 ppm per year. For the majority of plant species elevated CO₂ (eCO₂) improves photosynthesis and thus plant biomass production. To investigate the effects of eCO₂ on leaf physiology and morphological leaf characteristics two <i>Vitis vinifera</i> L. cultivars, Riesling and Cabernet Sauvignon, grown in the VineyardFACE (Free Air Carbon dioxide Enrichment) system were used. The VineyardFACE is located at Geisenheim, Rheingau comparing future atmospheric CO₂-concentrations (eCO₂, predicted for the mid-21st century) with current ambient CO₂-conditions (aCO<sub>2</sFrontiers in plant science1085878https://www.ebi.ac.uk/biostudies/studies/S-EPMC9782973biostudies-literatureGrapevine leaf physiology and morphological characteristics to elevated CO₂ in the VineyardFACE (Free air Carbon dioxide Enrichment) experiment.PMC9782973Papsdorf DWohlfahrt YKruger KTittmann SStoll MfalseGrapevine leaf physiology and morphological characteristics to elevated CO₂ in the VineyardFACE (Free air Carbon dioxide Enrichment) experiment.Atmospheric carbon dioxide (CO₂) concentration has continuously increased since pre-industrial times and has currently reached an average growth rate of 2.3 ppm per year.
