Accurate estimates of stand transpiration (E) require the consideration of three types of variation in sap flux density (J S): radial, azimuthal, and tree-to-tree variation. In this study, the J S variation of 50-year-old Korean pine (Pinus koraiensis) trees and its effect on E estimates was evaluated using Granier-type heat dissipation sensors. The value of J S decreased exponentially with the radial depth from cambium to pith, and the coefficient of variation (CV) for radial variation was 124… CONTINUE READING
