A study was carried out to compare the anatomical properties of Ash wood grown in different climate zones of Pakistan in order to find variations in their technological properties based on the wood structure. Results indicate that Ash wood grown in Kashmir and Quetta are nearly similar in strength and hardness in view of fiber morphological characteristics. Ash wood grown in Kashmir may be better in seasoning and preservation behavior due to its vessels frequency and diameter. Moreover, on the basis of parenchyma distribution Ash wood grown in Kashmir may be comparatively durable against biological decaying agents as compared to that of grown in Quetta, Balochistan.
