Bordered Pit Structure Observed by FE-SEM in Main Wood Species of Pinaceae Grown in Korea

An experiment was conducted to investigate the pit structure of four kind of pine wood species grown in Korea. Torus diameter, margo width, margo lattice size, diameter of pit aperture and pit border width were taken under consideration for explaining the pit structure difference among Pinus densiflora, Pinus rigida, Pinus koraiensis and Larix kaempferi. Torus diameter was found highest in Pinus rigida and the lowest in Pinus densiflora. Margo lattice size varied with torus diameter. Wider torus lowered the margo lattice size. Highest margo width was found in Pinus rigida while the lowest one was found in Pinus koraiensis. Pit aperture diameter was found highest in Pinus densiflora and lowest in Pinus koraiensis. In Pinus rigida, pit border was found the highest and the lowest was found in Larix ksempteri. Pit aperture diameter and pit border were increased gradually from pith to bark while there was a decreasing trend in the margo lattice size measuring from the pith to bark.
