Figure 7. Diel courses of simultaneous radial viscoelastic
changes in live bark (dD b) and xylem
(dD x) tissue as a result of change in osmotic
pressure potential in live bark (ΨΠb) and xylem (ΨΠx) inEucalyptus tereticornis trees (n = 6). Left-side panels show
viscoelastic changes below the girdle, right-side panels show these
changes above the girdle; top panels show these changes before (6-10
May) and after (bottom panels; 20-24 May) girdling of tree stems. Output
was generated using the mechanistic model described in Material and
Methods. Grey sections indicate night-time (19:00–07:00 h).
