An Investigation on the Physical, Anatomical and Fiber Biometrical Properties of Orange Wood (Citrus Spp.)

This research was aimed to investigate on the physical, anatomical and fiber biometrical properties of orange wood (Citrus Spp.). For this purpose, six discs of orange wood (Citrus Spp.) trunk from the Tonkabon region were randomly chosen. The samples were prepared for measured fiber biometrical, physical and anatomical properties by using Franklin and ASTM standard test methods respectively. The results showed that wood of orange wood had semi-ring porous, vessels are pairs of 2-3 group's vessels with simple aperture. The parenchyma's were longitudinal and around the vessels. There were a lot of heterogeneous rays in orange wood. The average of the number and vessel diameter were 14 and 89.5, ray thickness 41.4, fiber length 734.1, Runkel coefficient 136, dry density 0.75gr/cm3, basic density0. 64 gr/cm3, shrinkage and porosity 16.5 % and 49.2% percent, respectively. The results also indicated that orange wood properties were very fit and same the hard woods. The results also pointed out that the above-mentioned of orange wood properties can to replace some or full of the raw material for production pulp and paper, fiber board, particle board and another wood composition boards in the wood and paper industries.
