ABSTRACT
A number of wood species grown in Khyber Pakhtunkhwa have been studied for their anatomical properties in order to find out measures for wood quality improvement before their utilization for making various products. Permanent slides of cross, radial and tangential sections of each wood species were prepared, observed under the microscope and data were collected for the frequency and dimensional measurement of different wood elements/structures in each wood species. On the basis of results it was observed that Kiker, Robinia, Lachi and Gurgrua wood may be strong and hard and Toot, Kangar, Siris, Willow, Barh, Batkar and Jaman wood may be better or medium in strength due to longer, thick-walled or narrow lumened fibers. The wood of all the studied species may be somewhat non-durable because of higher frequency or larger size of wood rays and need preservative treatment before utilization in order to increase service life. Tut, Siris, Anjir, Willow, Kiker, Kangar Robinia, Gurgrua and Barh may be easy to season and preserve owing to higher frequency or larger size of vessels however whereas, Batkar, Lachi and Jaman wood may be somewhat difficult to process because of lower frequency or smaller diameter of the vessels.
