Anatomical properties and wood quality improvement of some low value timbers grown in AJK

ABSTRACT
Basic wood structure of seven low value wood species grown in AJK, was studied for the assessment of their technological properties helpful to improve quality of wood before utilization. Permanent slides of cross, radial and tangential sections of each wood species were prepared and data were collected for the frequency and dimensional measurements of various wood elements/structures in each species. Results showed that Lasura, Shreen, Dhak, Ritha and Tun wood may be better in strength due to longer and thick-walled fibers and Kao and Anjir wood may be medium in strength as the fibers are comparatively thin-walled. In order to increase service life, preservative treatment of wood before utilization may be necessary for all the studied species because of larger size or higher frequency of wood rays. Lasura, Shreen, Dhak, Tun and Ritha wood can be easily treated with chemicals and seasoned as the vessels are sufficient large in diameter whereas, Kao and Anjir wood may be somewhat difficult because of smaller diameter of vessels. Further, on the basis of fiber morphological characteristics, the wood of all the studied species may also be suitable for pulp and paper manufacture.
