Fig. 8.
Comparison of hydraulic pulse magnitude in different tree species. The relationship between the mean longitudinal strain εmean×initial water volume and the water volume expelled from the shoot during bending was plotted. The variation in the volume due to bending was computed for either (A) all the compartments, that is lumens and cell walls, or (B) cell walls only according to Equations 6 and 8, respectively (see the Materials and methods).
