| 总结: | The tall and straight bole of Kelempayan
(Neolamarckia cadamba (Roxb.) Bosser), a fast-growing
indigenous species, has the potential to be used for
forest plantation species. This study was carried out to
evaluate the inherent properties of the wood. Six planted
trees under similar site conditions were sampled along
their radii and at five different height levels to
evaluate the inherent variation of wood and the influence
of anatomical properties on its specific gravity (SG) and
bending strength. Over all me ans for SG was 0.36, green
moisture content 174.83 percent (%), tangential shrinkage
6.46%, radial shrinkage 3.28% and volumetric shrinkage
9.90%. The overall means for modulus of elasticity ( MOE)
and modulus of rupture {MOR ) were 7667 and 71 megapascal
(MPa) respectively. Vessel comprised 16.69% of wood, ray
11.96% and fibre 71.41%. Fibre length averaged 1.38
millimeter, fibre diameter 35.01 microns, fibre lumen
diameter 24.82 microns and fibre wall thickness 5.11 microns. These physical and mechanical properties are
similar to many other light hardwoods species, indicating
the suitability of wood for general utility timber. |
