Measurement of Water Movement from and Through Shrubs and Trees
Abstract:Three techniques whereby plant transpiration can be estimated or detected are presented. These are: (1) the tent technique--evapotranspiration measured by enclosing a plant in a flexible greenhouse and the rate of vapor production measured, (2) the quickweigh method--excised portions of plants are weighed to determine rate of water loss, and (3) the sap movement method -- sap velocity is measured and related to various parameters affecting the tree's rate of transpiration. Results from each of the three methods are presented along with a brief discussion of each method's advantages and disadvantages when compared with the other two.
