The purpose of this study was to examine the utilization of apple wood pruning as a raw material in particleboard manufacturing . In order to experimental boards were produced using pure apple wood particles and mixed to poplar particles , mat moisture content varied at 11, 13, and 15 precent and press time at 5 and 6 minutes.Thirty six sample boards ( 12 treatments ) were produced and tested . The results of physical and mechanical properties measurements were as follows : The results demonstrated that modulus of rupture (MOR) and modulus of elasticity (MOE) of boards produced under condition of mixed apple and poplar particles , 15% mat moisture content and 6 minutes of press time were higher than the other treatments . The results showed that increasing of press time had effect on internal bonding (IB) of boards , this trend was significantly higher in boards made of apple wood particles compare to the other boards. The results also indicated that , thickness swelling (T.S) after 2 and 24 hours water soaking were affected by raw materials ,and boards produced of apple wood particles had lower T.S than boards made of mixed wood apple and poplar particles. With regard to the physical and mechanical properties of boards, achieved the utilization of apple wood pruning residues could be recommended as a suitable lignocellulosic source in form of pure or mixed with poplar wood in particleboard industries .
