“…As a result, the growth rings were indistinct in the root wood, whereas they were distinct in stem and branch wood (Jeong et al, 2008;Lee, 1994;Park et al, 1981;Qi et al, 2014). These results also agreed with Fayle (1968b), Patel (1971), Stokke and Manwiller (1994), and Lee and Eom (2011).…”

“…Rao et al (1989) claimed that the average vessel tangential diameters, and vessel length of root wood were substantially smaller than those of stem wood. Stokke and Manwiller (1994) showed that for black ash (Quercus velutina) the vessel elements, fibers, rays, and axial parenchyma differed among stem, branch, and root woods. In addition, Palhares et al (2007) found that the amount of parenchyma cells and thin-walled fibers differed between root wood and stem wood.…”

This study investigated several anatomical characteristics of Paulownia tomentosa roots. The root wood was separated into three parts from stem base (top, middle, and base) at different positions below ground. Qualitative anatomical data suggested that the growth rings in earlywood and latewood were structurally different. Furthermore, the root wood vessels were found having 2 to 3 radial multiples and they were appeared in the form of clusters. In addition, some sheath cells and septate axial parenchyma were observed. Regarding the quantitative anatomical characteristics, vessel and ray numbers per mm 2 , as well as ray width and height differed significantly among the top, middle, and base rood wood parts. However, there were no significant differences in vessel diameters, cell wall thickness, and width and length of wood fibers among those parts. The crystallinity of the root top part was slightly higher than that of the middle and base parts. Furthermore, the vessel numbers, ray numbers, and ray width and height in the near pith (NP) area were higher compared to those in the near bark (NB) area. However, the fiber width and fiber length at NP were lower than those at NB. Overall, this study demonstrated some significant differences in the anatomical characteristics of the top, middle, and base parts of root wood from Paulownia tomentosa.
