Being an invasive technique, calibration is crucial to derive correction factors for accurately estimating the sap flow value from the measured heat pulse velocity.We compared the results of excision and perfusion calibration experiments made with mature olive (Olea europaea L. ‘Manzanilla de Sevilla’), plum (Prunus domestica L. ‘Songal’) and orange (Citrus sinensis (L.) Osbeck. ‘Cadenero’) trees. The calibration experiments were designed according to current knowledge on the application of the technique and the analysis of measured heat pulse velocities. Data on xylem characteristics were obtained from the experimental trees and related to the results of the calibration experiments. The most accurate sap flow values were obtained by assuming a wound width of 2.0 mm for olive and 2.4 mm for plum and orange. Although the three possible methods of integrating the sap velocity profiles produced similar results for all three species, the best results were obtained by calculating sap flow as the weighted sum of the product of sap velocity and the associated sapwood area across the four sensors of the heat-pulse-velocity probes. Anatomical observations showed that the xylem of the studied species can be considered thermally homogeneous. Vessel lumen diameter in orange treeswas about twice that in the olive and plum, but vessel densitywas less than half. Total vessel lumen area per transverse section of xylem tissue was greater in plum than in the other species. These and other anatomical and hydraulic differences may account for the different calibration results obtained for each species.This work was financed by the Direción General de Investigación of the Spanish Ministry of Science and Technology (Research Projects AGL2002-04048-CO3-01 and PTR1995-0693-OP-02-01).Peer reviewedOxford University PressMinisterio de Ciencia y Tecnología (España)201220122006info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/47489reponame:DIGITAL.CSIC.
