Özet: The growth of trees' lengths and diameters is influenced by many different environmental factors (growth, altitude, soil characteristics, annual rainfall, tree species, tree age, etc.). With the effect of these factors, the technical properties of the wood obtained from the trees also vary. Wood density is affected by environmental factors. Density and hardness value of wood gives important information about other technological properties. In this study, it was aimed to determine the static hardness values janka method and air densities in woods of the plum (Prunus domestica L.), black pepper (Piper nigrum L.) and chinaberry (Melia azedarach L.) tree species growing in Izmir region. Janka hardness values (tangential, radial and transverse surfaces) and air densities of wood samples were determined according to TS 2479 (1976) and TS 2472 (1976) standards, respectively. The data were evaluated statistically in SPSS 17 program. According to the research results; the density value of the plum wood was 860.73 kg/m3 and the density value of black pepper wood was 570.73 kg/m3. The highest janka hardness values were obtained from plum wood, and the lowest hardness values were obtained from black pepper wood.
