Descripción del servicio
The measurement of sap flow in trees allow us to estimate how much water is transpiring a plant and to determine its activity and whether it shows symptoms of water stress. Our technique is based on the method of compensation heat pulse and it consists in installing in the xylem of the tree a heater (needle) and two probes equipped with thermocouples, one upstream and another downstream of the transpiration flow. Besides estimating transpiration, under certain conditions it is possible to do an estimation of stomatal conductance automatically. Stomatal conductance is a very sensitive indicator of water stress.
The use of this service requires also the use of a datalogger (see services on loggers in this web page)
