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 ...

Business-driven IT for SAP The Model Information Flow [PDF]
2007 2nd IEEE/IFIP International Workshop on Business-Driven IT Management, 2007 Enterprises rely on efficient and flexible IT services. While complexity of services is increasing, personnel to provide and manage services will remain limited. At the same time, IT environments are becoming more dynamic, from the business side as well as from the infrastructure side.

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.

Nature, 1924 IN recent discussions on the upward movement of sap in trees, I have seen no mention of an interesting observation of Charles Darwin to be found in his “Voyage of the Beagle” (p. 258, John Murray, 1912 edition). He was exploring the Campana or Bell Mountain about 26 miles from Valparaiso, and he writes as follows, for the quotation is worthy to be ...

OENO One, 2023 In order to investigate the effect of age and pruning characteristics on grapevine hydraulic conduction, a study was carried out between 2017 and 2020. Two pruning regimes (respecting or not sap flow pathways) and two vine age levels (older and younger ...

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 ...
