| Anatomical characteristics of the secondary xylem in the roots and the stems of genus Pinus including nine species growing naturally in Korea have been studied to elucidate the structural differences between two organs. The results, comparing the root woods with the stem woods, are as follows; The transition from the early-wood to the late-wood occurs more gradually in the root woods. In the root woods, the bordered pits on the radial wall of tracheid are frequent in the two rows. The spiral thickening on the radial and tangential wall of the tracheid can be seen in the only stem woods of four species such as P. koraiensis, P. rigida, P. rigitaeda and P. banksiana. In the majority of the species studied, the length of the tracheid is longer in the root woods, but in some species such as P. strobus, P. densiflora, P. rigida and P. sylvestris, this length is almost sam ein both organs. The diameter of the tracheid in the root woods is wider. The wall thickness of the tracheid in the early wood is thicker in the root woods, but vice versa in the late woods. More rays per unit area can be seen in the root woods. |
