Wood anatomy of Aleppo pine (Pinus halepensis Miller) grown naturally in Turkey

Aleppo pine (Pinus halepensis Mill.) is the least grown pine species in Turkey with two small forests. A total of 18 wood samples, 6 samples from the northern slope and 6 from southern slope of Sırtlandağı in Milas-Muğla and 6 samples in Yumurtalık (Adana) were collected. Tracheid and ray dimensions were measured on the photos of the thin wood sections. As result, diameters of the earlywood tracheids in Aleppo pine are similar in both Adana and Muğla, while diameters of latewoods are wider in especially on north aspect of the site in Muğla than Adana. The reason for this difference may probably be that the annual precipitation in Muğla is two times higher than that in Adana. Supporting the effect of lower precipitation in Adana, tracheid lengths are longer, tracheid frequency are higher in Adana for a safety water transportation. All comparisons with the woods from Spain and Greece may be evaluated that the growing site conditions in Turkey are more favorable for the species and may be used in plantations. Furthermore, wood features in both Turkish and Aleppo pine species are very similar and their separation is almost impossible.
