Table 1. Effect of time on SC and starch concentrations in leaf, twig, branch, trunk (trunk peripheral region [trunk P] and trunk C), root, and sap.
P values obtained from an ANOVA performed on a nonlinear mixed-effects model are shown. Minimum and maximum values (mean ± se) and time of NSC diurnal trends were calculated on five trees.Starch was not detected in sap (no signal (ns).
