Summary :

In a context of global changes where the increasing intensity and frequency of stresses are endangering many organisms, the sustainability of woody plants requires a better understanding of their vulnerability and adaptive capacity. Access to high-throughput characterisation of the response of woody plants to these stresses is therefore a major challenge. Through this project, we propose to study the potential of near-infrared spectrometry to estimate complex characters related to the response of trees and vines to stresses. Near infrared spectrometry is a rapid analysis method that is of twofold interest: 1) to increase the sampling effort for complex traits to be measured, 2) to enable the prediction of the response to a stress before the expression of symptoms. The range of stresses studied in the project mainly covers vulnerability to water stress and bio-aggressors. The project aims to develop an operational tool for woody plant improvement programmes, ecosystem management (forest, alluvial) and viticulture.
