Leveraging sap flow data in a catchment-scale hybrid model to improve soil moisture and transpiration estimates [PDF]
Hydrology and Earth System Sciences, 2022 Sap flow encodes information about how plants regulate the opening and closing of stomata in response to varying soil water supply and atmospheric water demand.

Liquid-solid interaction at nanoscale and its application in vegetal biology [PDF]
, 2011 The water ascent in tall trees is subject to controversy: the vegetal biologists debate on the validity of the cohesion-tension theory which considers strong negative pressures in microtubes of xylem carrying the crude sap. This article aims to point out

MICROMETEOROLOGICAL AND SAP FLOW MEASUREMENT OF WATER VAPOUR EXCHANGES IN OLIVE: SCALING UP FROM CANOPY TO ORCHARD [PDF]
, 2009 A comparison of water consumption evaluated at tree and orchard level was carried out in a commercial olive orchard located in Sicily using up-scaled sap-flow evapotranspiration estimations and eddy covariance measurements. Sap flow probes were installed

Transient response of sap flow to wind speed [PDF]
Journal of Experimental Botany, 2008 Transient responses of sap flow to step changes in wind speed were experimentally investigated in a wind tunnel. A Granier-type sap flow sensor was calibrated and tested in a cylindrical tube for analysis of its transient time response. Then the sensor was used to measure the transient response of a well-watered Pachira macrocarpa plant to wind speed ...

SAPFLUXNET: towards a global database of sap flow measurements [PDF]
Tree Physiology, 2016 Plant transpiration is the main evaporative flux from terrestrial ecosystems; it controls land surface energy balance, determines catchment hydrological responses and influences regional and global climate. Transpiration regulation by plants is a key (and still not completely understood) process that underlies vegetation drought responses and land ...

Sap flow and water transfer in the Garonne river riparian woodland, France : first results on poplar and willow [PDF]
, 2002 This work is the first attempt at using Granier sap sensors on Populus nigra, Populus x euramericana cv I45/51 and Salix alba for the monitoring of sap flows in an active floodplain over two consecutive years.
