Study on the Basic Properties of Platanus occidentalis L. for Its End-use Development

양버즘나무의 용도개발(用途開發)을 위(爲)한 기초재질시험(基礎材質試驗)

This study was carried out to investigate the wood qualities for the end-use development of sycamore (Platanus occidentalis L.) grown in Korea. The results obtained were as follows: 1. The average length of wood fibers was l.56mm and the average width of annual rings was 9.5mm. It had very fast growth rate. 2. The specific gravity in air-dry was 0.66. The shrinkage and water absorption were relatively large. The shear and impact strengthes were very strong, while the compressive, tensile, and bending strengthes were weak in comparison to it's specific gravity. 3. The contents of ash, holocellulose, lignin were relatively high 0.74%, 83.08%, 28.79%, but that of pentosan was low 18.53%. 4. The expected uses of sycamore wood are plywood. fancy veneer, small furniture, musical instrument, door and window frame, tool handels, boxes, etc.
