  • A wooden coffin estimated to be made in Baikjae Dynasty in AD. 6 century was excavated from ancient tombs in Nung-san ri, and examined to identify its wood species using light and electron microscopy. Wooden part attached to oxdized complex around the iron nails on the coffin was electro-chemically separated to prepare the samples for observation. The results revealed that 24 samples out of 28 samples investigated were identified as Torreya nucifera, while the rest 4 samples were identified as Pinus densiflora.

  • A simple method for identifying of ectomycorrhizal fungi was presented, using the polymerase chain reaction (PCR) to amplify the ITS (Internal transcribed spacer) regions of the nuclear ribosormal repeat. The sequences analyzed 6 species, Pisolithus tinctorius, Chroogomphus rutilus, Leucogyrophana pinastri, Suillus granulatus, Lactarius laeticolorus, and Suillus bovinus at hongreung forest, and analysed 10 species, Craterellus lutescens, Thelephoroid mycorrhizal, Lactarius quieticolor, Tricholoma matsutake, Lactarius chrysorrheus, Sarcodon aspratus, Russula versicolor, Suillus luteus, Tricholoma terreum, and Amanita vaginata at hongcheon forest. Finally, the amplification by PCR with ITS1-ITS4 primers offers good results over classical identification for ectomycorrhizal fungi species.

  • The purpose of this study is to identify the species of wood members used in the Keunjungjeon Hall, main building of the Kyungbok palace in Seoul. The total 144 samples consist of 52 from pillars and 92 from other wood members. Only two species were identified, which were Abies holophylla Max. (needle fir) and Pinus densiflora Sieb. et Zucc. (Japanese red pine). For the pillars, A. holophylla were more abundantly used than P. densiflora. Among 20 outer pillars ('Pyeongju'), 11 were A. holophylla, and 9 were P. densiflora. Among 12 inner pillars ('Naejinkoju'), 7 were A. holophylla, and 5 were P. densiflora. Among 4 inner corner pillars ('Gwikoju'), 3 were A. holophylla and 1 was P. densiflora. For 92 other wood members, only 2 purlins were A. holophylla and the others were all P. densiflora. The results suggest that the common opinion 'Palace buildings of Korea are made from red pine woods' should be corrected. We think that fir logs might be used for the pillars instead of pines because long and straight pines were not available during 1860s due to heavy utilization of pines as construction and fuel materials in the late Chosun period.

  • Aggravation of natural environment, improvements in income, internet diffusion, spread of five-day work a week, and population aging seem very different from each other. However they boil down to consumption. These culture patterns are changing into environment-friendly and productive housing culture. In other words, people might tend to have frequent contacts with not only environment-friendly housing in bustling cities but also woods that is environment friendly materials in their leisure time. In the period of people young and old alike are in favor of woodcrafts, this study was conducted for giving information to who speicalized in woodcrafts. Furthermore, the study shows that other countries also added grain and figure to woodcrafts for visually appealing.

  • The purpose of this study is to examine the species of wooden members used in the Youngsanjeon Hall of the Sucknamsa temple in Anseong, Korea. Ninety-five wood samples from pillars, head-penetrating ties, beams, corner rafter, rafter, floor board and other wood members were identified. Seven species identified were hard pine, exotic pine, Zelkova serrata, Ginkgo biloba, Diospyros, Quercus(Cerrus) and Pyrus spp. In the case of pillars, eight were hard pines and the others Zelkova and Pyrus. Species of angle rafter were Ginkgo biloba and Zelkova. and those of beams were one hard pine and one Zelkova. Two purlin samples were Quercus(Cerrus) and rafters were hard pines except one Ginkgo and one exotic pine. Roof-filling timbers were identified as Zelkova and Diospyros spp. The other samples of roof-filling timbers were all identified as hard pines. The use of Ginkgo and several hardwoods in addition to hard pines may indicate supply of local logs near the Sucknamsa temple.

  • A database system for retrieving the information on wood collections was developed using the D-BASE III Plus program for personal computers. Basic information of biological, physical, chemical and technological properties was added to the data which used to be employed in simple card systems, such as identification number, species name and collection site. All information was fast and reliably retrievable. This paper also discussed the results of a survey on wood collections housed at domestic colleges and research institutes.

  • Juvenile and matured wood of Populus tomentiglandulosa species of Salicaceae native grown in Korea was observed by FE-SEM and optical microscope. Species is characterized by mostly diffuse-porous, simple perforation plates, polygonal alternate non-vestured intervessel pit, medium length of vessel elements and fibres, non-septate very thin walled libriform fibres and exclusively uniseriate procumbent rays. Axial parenchyma was absent or extremely rare. Vessel and fibre length were longer in both matured and juvenile latewood than those of earlywood. Ray cell lumen diameter, ray length, number and diameter of endwall pit in ray cell, endwall pit, number and diameter of pit in lateral wall of one ray parenchyma cell, vessel ray pit number and diameter vary from juvenile early and latewood to matured wood.

  • A chinese wood species called China Hongmu, is an excellent wood to make high quality furniture owing to attracting color, beautiful grain, and durability. Hongmu is not a tree or wood species name. The general designation in Hongmu group is a similar to one of its density, structure, color and use. Hongmu considers more than 30 hardwood species of Pterocarpus, Dalbergia, Diospyros, Millettia, and Cassia. According to the macrostructural characteristics and properties, Hongmu group can be classified into 8 groups which are Zitanmulei, Hualimulei, Heisuanzhimulei, Hongsuanzhimulei, Xiangzhimulei, Wumulei, Tiaowenwumulei and Jichimulei. In this paper, the growing areas, scientific names and identifiable characteristics of these Hongmu group species were introduced for help to identify China Hongmu and its products in the market as well.
