“…Another popular sap flow method, the thermal dissipation or Granier method, has also been demonstrated to underestimate transpiration with as much, or more, error than HPV methods [9,24,43]. Rather, this review is a caution to scientists to not rely on theoretical calculations of transpiration from HPV or any sap flow method.…”

“…Rather, this review is a caution to scientists to not rely on theoretical calculations of transpiration from HPV or any sap flow method. If an estimation of transpiration is the aim of a study, HPV sap flow sensors can certainly be deployed, but they must be carefully calibrated [21,43]. Any study that presents transpiration data from uncalibrated sap flow sensors should be regarded with extreme caution.…”

“…Five oak branches and two male mistletoe plants were selected for sap flow measurements using the heat field deformation (HFD) method (Nadezhdina et al 1998;Čermák et al 2004;Steppe et al 2010), which accounts for the size and overall distribution of the branches in the crown. Given the small size of the oak and mistletoe branches, the sap flow rate was only measured at one depth, 2-3 mm below the cambium, by single-point HFD sensors (Dendronet, Inc. Brno, Czech Republic).…”

“…Sap flux density measurements give precise information on flow directions as well as spatial and temporal flow distribution (Vandegehuchte and Steppe, 2013). The heat pulse velocity (HPV) method is the most accurate of the available methods when compared against gravimetric methods (Steppe et al, 2010;Vandegehuchte and Steppe, 2013).…”
