Résumé

It is predicted that worldwide CO2 concentration will continue to increase (IPCC 2014) and that regional weather patterns will alter substantially. Elevated atmospheric CO2 concentrations can stimulate photosynthesis and induce stomatal closure affecting carbon uptake and water use. However little is known about the interaction between CO2 and abiotic/biotic constraints and about the genetic variability of the response to its atmospheric concentration. Thus, the development of strategies for adaptation and acclimation of crop productions to changing environmental conditions requires large scale studies in all fields of plant research and production.Systems to study elevated CO2 on plants grown under open field conditions, so called Free Air CO2 Enrichment (FACE) systems, have proven their relevance in providing information in conditions closer to agronomic situations than plants grown in greenhouses and open top chambers. The urgent need for new FACE facilities was already expressed in 2007 at a European Science Foundation meeting. The focus was on analysing long-term soil impact and plant response in the context of breeding.Almost 10 years after, two national plant phenotyping platforms have incorporated a FACE system in their infrastructure. These are the Phenome: French Plant Phenomic Center (www.phenome-fppn.fr) and the German plant phenotyping network (www.DPPN.de). Both platforms equipped with the latest phenotyping techniques will be completed in the coming year. The similar technology and design used in both FACE systems allow for the unique opportunity of testing breeding populations or specific crop cultivars at elevated CO2 in two different regional climates. The synergy between the two FACE installations could be the first step towards a European consortium of FACE rings to answer important questions on increasing yield for food security under future climate conditions.
