ETAP : Efficiency of Transpiration and Adaptation of Plants to dry climates

Themes

The ETAP team (Transpiration Efficiency and Plant Adaptation to Dry Climates) seeks to identify genetic and agronomic levers of action that can be used to improve water use efficiency in viticultural systems subject to abiotic constraints.
The genetic variability of tolerance to drought, high temperatures and, more recently, low input levels (nitrogen) is understood in detail at the foliar level via the development and use of simulation models of transpiration, water status in the plant and photosynthetic activity. At the more integrated scale of the whole plant, tools for reconstructing the structure of the vine in 3D for different genotypes and for contrasting pruning and trellising systems are developed. These tools make it possible to simulate the microclimate within the plant and to model gas exchanges in the canopy by integrating the models developed at the leaf scale. Analysis of the establishment of early yield components in response to high temperatures has also been undertaken, with particular emphasis on the role of carbonaceous metabolite availability.
This work is based on joint projects with local (UMRs AGAP, BPMP, SPO, SYSTEM and INNOVATION), national (UMR EGFV Bordeaux) and foreign (University of the Balearic Islands, Spain; University of Lisbon, Portugal; Geisenheim Centre, Germany, INTA, Argentina) partners. Local collaborations with the UMR AGAP make it possible to explore the margins of genetic progress, while collaborations with the UMR System aim to optimise management methods.
