Relationships between thicknesses of G-layers in tension wood of stems of inclined seedlings of F. moluccana, A. heterophyllus and D. celebica and stem recovery degrees (R°s) three months after pots had been inclined. The straight solid line shows that the thicknesses of G-layers were positively correlated with R°s in all three species examined. The straight dashed lines show the relationships between widths of regions of tension wood and R°s in each species examined. The thicknesses of G-layers were positively correlated with R°s in A. heterophyllus and D. celebica. Each symbol represents a single set of measurements from a single seedling. *, Significantly different at P < 0.05; **, significantly different at P < 0.01; (ns), not significantly different
