ABSTRACT
This study was carried out to evaluate the suitability of some hardwood species growing in Lalkoo, Swat based on morphological characteristics of wood fiber. For this purpose, wood samples were collected from local depots and wood fibers from each species were separated adopting standard laboratory procedures. Results showed that Walnut (Juglans regia) fibers were comparatively longer in llength followed by Pohu (Parotia jacouemontiana), Mulberry (Morus alba), Black locust (Robinia pseudoacacia), Himalyan yew (Taxus wallichiana), Indian willow (Salix tetrosperma), Brown Oak (Quercus semicorpifolia), Tree of Heavan (Allianthus altisimia) and Himalayan poplar (Populus ciliate) while fibers of Salix tetrosperma were found with small diameter followed by Ailanthus altisma, Quercus semicorifolia , Morus alba, Juglans regia, Populus ciliate, Parotia jacouemontiana, Taxus wallichiana and Robinia pseudoacacia. The fibers wall was found comparatively thin in Populus ciliate followed by Taxus wallichiana, Ailanthus altisma, Quercus semicorifolia, Salix tetrosperma, Juglans regia, Morus alba, Parotia jacouemontiana and Robinia pseudoacacia while Runkel ratio was found comparatively very low in Morus alba 0.12 followed by Ailanthus altisma 0.22, Robinia pseudoacacia 0.24, Taxus wallichiana 0.50, Populus ciliate 0.62, Juglans regia 0.86, Quercus semicorpopifolia 0.94, Parotia jacouemontiana 0.96 and Salix tetrosperma 1.00. Based on the results it was concluded that all wood species except Salix tetrasperma can be selected for manufacturing of pulp and paper products.
