Fig. 5. A, Relationship between mean pith volume and mean leaf volume for metamers forming the different axis parts for individuals at different developmental stages. A 95% confidence interval is associated with each mean. The axes are graded on a logarithmic scale. B, Interpretation of Rubus alceifolius organization and functioning on the basis of the axialization and foliarization concepts. The shading (dark to pale) highlights changes for each developmental stage and along different axes with respect to level of axialization and foliarization, indicating the autotrophic and environment‐tapping or exploring potential of plants during their development. Grey rectangles indicate the presence of a rooted stock.
