A Review of Wood as Material and Source of Innumerable Products

As we known that “ wood – which is a source of innumerable pruducts (Tsoumis, 1968)– is a fascinating and challenging material (Dinwoodie, 1975)” , and hence, “ an understanding of the basic properties of wood and of the factors that affect its serviceability is vital background for the preservation of wood structures (Sherwood, 1986)” . This paper therefore presents an overview of structrural properties of wood (based on the softwood species) and the aspect of of wood material for its serviceabilty. The emphasis was given to introduce wood as a material and a source of innumerable products by the detailed coverege of the subject. This paper includes information with the extensive list of references by the following subtitles: 1. The Nature of Wood 2. Anatomical Structure of Softwood 2.1. Macroscopic Structure 2.1.1. Characteristics of Transverse Surface (cross-section) 2.1.2. Characteristics of Tangential Surface 2.1.3. Characteristics of Radial Surface 2.2 Microscopic Structure 2.2.1. Tracheids 2.2.2. Rays 2.2.3. Resin Canals 2.3. Ultra-structure 2.3.1. Cell Wall Layers 2.3.2. Cell Wall Pits Simple Pits Bordered Pits Semi-Bordered Pits 2.4. Pit Aspiration 3. The Value of Wood as Raw Material 3.1.
