영문 초록

This study aimed to update a database of anatomical characteristics of commercial coniferous trees, mainly distributed in Korea, and to observe anatomical characteristics. The wood samples were for example Pinus densiflora (ages: 90, diameter at breast height: 34.4 cm), Pinus rigida (ages: 50, diameter at breast height: 33.7 cm), Larix gmelinii (ages: 84, diameter at breast height: 33.5 cm), and Larix kaempferi (ages: 93, diameter at breast height: 40.6 cm). Three sections of each wood samples were examined with an optical microscope to observe the anatomical features, and the tracheid length was measured in units of five growth rings from the pith to the bark. Also, the width of the growth ring and the ratio of the latewood were measured to estimate the wood properties. Typical anatomical characteristics have been found in samples of coniferous trees. However, the average tracheid length value was the longest for Larix kaempferi, 2.91 mm for earlywood, and 3.31 mm for latewood. When the juvenile wood and mature wood were classified according to the difference in tracheid length, the boundary line is considered to be 20~25 growth rings. The width of the growth ring and the latewood ratio were also marginally greater in Larix kaempferi. Since coniferous woods are used for various purposes, such as wood structures and furniture, the results of this study are expected to provide basic data for the use of coniferous woods.
