We used 30-mm long heat dissipation probes (Model TS30; Dynamax Inc., Houston, TX) implanted at 1.5 m height on the stems of intact trees and approximately 1 m above the cut in potometer trees.
1981) were attached to the potometer trees at approximately 1.75 m height.
The larger Ochroma tree in potometer 2 (DBH = 15.6 cm) exhibited visible signs of wilting by 1000 h of the first day of observation.
However, HDT performed poorly at measuring nocturnal water uptake, as estimates did not show any consistent relationship with the values measured in potometer trees (Tables 1 and 2).
