"Combining proximal sensing and flux measurements to detect physiological and structural response of vegetation in manipulation experiments"

October 5, 2017

Summary

Hyperspectral remote sensing  can be used to directly infer variation in structure and function of the vegetation under different environmental conditions or stress. Among the variety of products, sun-induced fluorescence (SIF)  provides a new non-invasive measurement approach that has the potential to quantify dynamic changes in light-use efficiency and photosynthetic carbon dioxide uptake (Gross Primary Production, GPP). However, the mechanistic link between GPP and sun-induced fluorescence under different environmental conditions, and in particular stress, is not completely understood. In this contribution I will show the structural and functional factors controlling the emission of SIF in a series of manipulative experiment. I will also show the potential of the use of SIF retrieved in the red and far red to determine environmental stress on vegetation
