Abstract

In the context of global warming, the INRAE PIAF joint unit (Integrative Physics and Physiology of Trees in Fluctuating Environments) and the SUREAU team (Hydraulic Safety and Drought Resistance of Trees) are monitoring the propagation of summer embolism (cavitation) in trees. To monitor this embolism, the Xyl'em apparatus was originally used, but this is a destructive hydraulic technique requiring a large quantity of plant material. therefore, we opted for the optical method, which we have adapted to our needs. This technique is based on two devices, a scanner and a cavicam (Raspberry Pi + camera), complemented by an image processing in ImageJ. Automatic photos or scans are taken every 5 minutes, and the photos are processed after the experiment to visualize embolism formation and propagation over time. The optical technique offers several advantages: it requires less plant material and saves time because it is semi-automated. This technique is currently being improved at UMR PIAF to make it more precise.
