Abstract
Most of Sudan forests are degraded natural forests which have been creamed. The remaining stock is composed of some secondary species which are not used even for firewood or charcoal. Therefore the objective of the present study is to determine some basic properties and quality attributes for four secondary species growing in Blue Nile State and assign the different species to the recommended uses according to their properties and quality attributes. This is to increase the number of wood species in use and make it more economical to harvest and exploit natural forests sustainably.The basic properties determined included some anatomical fiber characteristics. Fiber length and cell proportionswere determined using stereological techniques,Physical and mechanical properties were carried out in accordance to standard testing procedures. Analysis of variance and Duncan?s Multiple Range Test revealed significant variations in almost all properties between the species studied. The details are given in the first paper. (tables 1-4). However, for the purpose of this paper Correlation analysis was also carried out to find relationships between wood basic properties (anatomical and density) and wood quality attributes for the different uses like wood strength, dimensional stability, permeability, gluability and appearance. These attributes represent the characteristics needed to sort the different species for the most suitable uses. According to its properties and quality attribute goghan was found suitable for structural uses, high quality furniture internal decorations, carving, handcraft, veneer and high quality plywood. kakamut on the other hand, had similar quality attributes to goghan and can be used for the same uses with preference to goghan. Talh was assigned for structural uses, fixed furniture for student seating and at camping sites. It can also be used for fiberboard and pulp and paper production. Tarar, however, was found suitable for non ?load bearing partitions and as an insulating material in sandwich construction as well as for fiberboard and pulp and paper manufacturing. Its low density also makes it suitable for the manufacture of particleboard.
