Fig. 1

Transverse section scanned by microCT showing the dynamics of xylem embolism in leaf petioles of P. tremula (panels a–c), B. pendula (panels e–f), L. tulipifera (panels g–i) and O. europaea (panels j–l). Water-filled and embolized conduits appear as light grey and dark, respectively. Values in each panel indicate stem water potentials at which trees were scanned. Scale bars indicate 150 μm for all images. Blue and red arrows indicate water-filled and air-filled vessel, respectively
