Sap Velocity Studies in Natural Stands of Pinyon and Juniper Trees
Journal of range management
Highlight: Sap velocities in pinyon (Pin& edulis Engelm.) and juniper (Juniperus osteosperma (TOW.) Little) trees in southeastern and southwestern Utah were studied for 1 year using the heat-pulse technique. Measured velocities were related to nearby environmental factors and Dalton's simplified aerodynamic method for estimating evaporation from water. Sap velocity was independent of the dry weight of green biomass within both pinyon and juniper trees. From 90.5 to 99.0% and from 66.0 to 99.0%doi:10.2307/3897498 fatcat:iqnhkcmivvdofds62cswmassdi
