Bitter orangewood (Citrus aurantium L.) belongs to the Rutaceae family. It is called by different names in various languages and country for example; naranja ácida, naranja agria, or naranja amarga (Spain), naranji; (Arabia), melangolo (Italy), khatta (India), moli (Samoa), soap orange (Guam). The hard, white or light-yellow wood is used in woodworking, turning, cabinet making, and baseball bats. The mechanical and physical properties of each tree species help to create important information about the use of wood. In this study, air-dry density value, bending resistance, modulus of elasticity in bending, impact bending strength, screw holding resistance (tangent, radial and transverse) were determined on wood samples of bitter orange tree grown in İzmir. According to the results obtained; air-dry density value (D12) 868 kg/m3, bending resistance 134.7 N/mm2, elasticity modulus 8988 N/mm2 in bending, impact bending strength 0.683 kgm/cm2, screw holding resistance 55.8 N/mm2 at tangent surface, 57.7 N/mm2 at radial surface and 52.6 N/mm2 at the transverse surface. It has been observed that these results are higher compared to many tree species.
