My research activities, at the interface between ecophysiology, phenomenology and crop modeling, aim at improving varieties in the context of climate change and new agricultural practices. Today, I focus mainly on the analysis of genetic diversity of leaf development and transpiration under environmental constraints such as high temperature and water deficit, and its impact on field yield. This defines the following three axes:
- Intra- and inter-specific diversity of temperature responses
- The hydraulic control of transpiration and leaf expansion in maize under water deficit and high evaporative demand.
- Interactions between nitrogen, high temperature and water deficit on growth and aerial development in wheat
I developed a conceptual framework to predict the impact of genetic diversity of adaptive traits under different environmental scenarios and cropping practices of today and tomorrow.
1) Develop process-scale models based on phenotyping and improve crop models.
2) Analyze the intra- and inter-species genetic diversity of model parameter values, as well as the constraints defining the phenotypic parameter space.
3) Determine the genetic architecture of the model parameters by quantitative genetics.
4) Predict the adaptive value of different combinations of traits (functional ideotypes) and multi-allelic combinations (genetic ideotypes) at large scale.
