Fig. 10. Comparison of sap flux density predicted with Granier’s original equation and other calibrated equations for field grown Populus tomentosa (mean ± SE). Different lowercase letters indicate a significant difference at p <0.05, according to Tukey’s test. M1, Granier’s original equation; M2, calibrated equation of stem-weighing method; M3, calibrated equation of whole-tree potometer method; M4, calibrated equation of Ma et al. (2020); M5, calibrated equation of Xie & Wan (2018).
