The negative regression between tensile strength (<i>T</i>_<i>r</i>) and diameter (<i>D</i>_<i>r</i>) was attributed to the decrease in cellulose content. The positive regression between <i>T</i>_<i>r</i> and stele percentage was attributed to the dominant distribution of cellulose within the stele of root. Pores in plant root could weaken the macro-biomechanical properties, with trees generally having higher porosity than shrubs in this research species.
