Scatter plots of a relationship between CBL and HAC/CBL. We recognized individuals showing quite lower HAC by the following definitions as old aged (greyish zone, see text): HAC/CBL ≤ 0.14 and CBL ≥ 27.0 mm. White and black circles indicate immature and mature individuals, respectively (Appendix 1: Table A1). Arrows indicate individuals showing incipient roots (see text and Appendix 1: Table A1).
