The Use of Sap Flow Gauges for Estimating Transpiration

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Dynamics of transpiration, sap flow and use of stored water in tropical forest canopy trees.

In large trees, the daily onset of transpiration causes water to be withdrawn from internal storage compartments, resulting in lags between changes in transpiration and sap flow at the base of the tree. We measured time courses of sap flow, hydraulic resistance, plant water potential and stomatal resistance in co-occurring tropical forest canopy trees with trunk diameters ranging from 0.34-0.98...

Age-related decline in stand water use: sap flow and transpiration in a pine forest chronosequence

We investigated changes in the pattern of stand water use in a chronosequence of four even-aged maritime pine stands, differing in age (10-, 32-, 54and 91-year old) and growing under similar environmental conditions. Extensive sap flow measurements were carried out during a period of 2 years (2001–2002), using thermal dissipation sensors located 1 m below the live crown and corrected for the ra...
