Abstract

•Earlywood and latewood effects on SFD-based transpiration estimates in conifers were investigated.•Radial SFD variability in central sapwood was closely linked with EW and LW variations of conifers.•Actual flow was underestimated by assuming only EW was water-conductive or thermal diffusivity was that of EW.•LW/EW ratios can be measured a posteriori to correct HRM-based sap flow measurements.•Radial SFD correction from HFD sensors should be conducted at the same location of HRM measurements.
