RADIAL VARIATION IN MICROFIBRIL ANGLE OF SUPER AND COMMON TEAK WOOD
Teak wood (Tectona grandis L.f.) is a well known and relatively slow growing hardwood species and popularly used as furniture and construction timber. Recently fast growing teak has been introduced which is named as super teak, as opposed and existing common teak. The quality of super teak however, is being questioned and suspected to be not as common teak. Microfibrils angle is one parameter of timber quality. It represents the angle between microfibrils and wood fiber axis when they are incorporated in a helical fashion to from fiber structure. The angel was measured from the orientation of long axis of elongated pits fiber. The mean angle of common teak was 22.05', which is narrower than that of super teak of of the same age, which was about 23.29'. Genetic factor is suspected to be the source for angle differences. In relation to wood stability during drying,it was predicted that common teak timber was more stable than that of super teak timber in the same age. In radial direction, the mean angle of both super and common teak declined from inner to intermediate and outer wood. The tendency for microfibrils angles hto be higher in the center of the log has some important implications for wood processing and tree improvement.
