Visualizing embolism in leaf at BIOGECO

A new technique to measure resistance to water stress

By imaging a laurel leaf at 3 min intervals and by subtracting the difference between the images to see where an embolism formed, we were able to determine at which water potential laurel leaves cavitate. Images were colorized by how much time had elapsed and combined to give a complete picture of the plant’s response to water stress.

This new technique to measure resistance to water stress was developped in Brodribb et al (2016) and is now running at the GENOBOIS Platform Caviplace


Measuring leaf potential
with a psychrometer

Leaf scanning

This study was conducted by Déborah Corso, Laurent J Lamarque, Gaëlle Capdeville, José Manuel Torres Ruiz, Régis Burlett and Sylvain Delzon.

It has been carried out with financial support from the French National Research Agency (ANR) in the frame of the Investments for the future Programme, within the Cluster of Excellence COTE (ANR-10-LABX-45).
