A microcomputer-controlled heat-pulse system for the measurement of sap velocity in trees is described. Several published methods for determining sap velocity from the temperature rise measured either above or below a heater inserted into the stem were compared and evaluated. All methods could be im

## Abstract The amount of water stored in the stem introduces uncertainty when estimating diurnal wholeβtree transpiration (__E__~T~) and canopy stomatal conductance (__G__~C~) using sap flow measured at the base of the stem (__Q__). Thus, to examine how __E__~T~ can be calculated from __Q__, we ob
