- Note: Different lowercase and capital letters at the superscripts represent the significant difference at P < 0.05 and P < 0.01 respectively. Ψp (phloem)-estimated is the phloem turgor pressure estimated with the equitation, Ψp (phloem)-PTPP means the phloem turgor pressure measured with PTPP method and Ψp (phloem)-MTM represents the phloem turgor pressure measured with MTM method. For each Tree, Ψs(phloem) is the mean of at least 3 latex samples collected from three punctures. Ψp(xylem) is the mean of minimum 3 bagged twigs and Ψs(xylem) is the mean of at least 3 xylem sap samples pressed out from the twigs used for Ψs(xylem) determination. Ψp(phloem)-PTPP is a single measurement after the PTPP was well balanced while Ψp(phloem)-MTM is the maximum value of up to five MTM measurements. Ψp(phloem)-estimated is calculated from the means of Ψp(xylem), Ψs(xylem) and Ψs(phloem) of the Trees.
