In this study, relationships between site index and some physical properties (e.g, air-dry and ovendry densities, and volumetric shrinkage and swelling ratios) of calabrian pine (Pinus brutia Ten.) wood obtained from Kahramanmaras state forests of Turkey were investigated. The results showed that these physical properties of the wood obviously decreased with increasing site index number, and there were good relationships between the physical properties of the wood and soil characteristics. The results of statistical analyses indicated that site index had an important impact on the physical properties. Significant differences in the air-dry and ovendry densities between site index I and site indexes II and III were determined and there were significant differences in shrinkage and swelling ratio among all the types of site index (I, II, and III). Furthermore, differences in the physical properties of the calabrian pine among the site indexes could be attributed to different bedrock types and soil properties of sites.
