Anatomical and physical characteristics of Korean paulownia (paulownia coreand) branch wood

초록

The anatomical and physical properties of tension wood (TW), opposite wood (OW) and lateral wood (LW) in the branches of Korean paulownia {Paulownia coreana) were compared. The diameter of TW vessels was larger than that of OW and LW vessels. The most distinctive feature of TW fibers was the presence of a gelatinous layer (G-fiber). The cell wall of TW fibers was nearly three limes as thick as that of OW and LW. TW differed from OW and LW in density. X-ray diffraction pattern and shear and compressive strengths. The results obtained in this study showed clear differences in the anatomical and physical properties of TW. OW and LW of Paulownia coreana branch woods.
