Compression wood is a reaction wood occurs in the softwoods with the effect of external factors. Compared to normal wood there are differences in chemical, anatomical and physical-mechanical properties. In this study, compression wood of Scots pine (Pinus sylvetris L.), Black pine (Pinus nigra Arnold.) and Calabrian pine (Pinus brutia Ten.), used widely in industry and grow naturally in Turkey, were studied microscopical. Microscopic structure of compression wood of Scots pine and Black pine were not studied before in Turkey. However, to the best of our knowledge Calabrian pine of compression wood was analyzed for the first time.

Samples were obtained from Bartın–Kurucaşile and Bolu–Mengen, Turkey provience. Control samples were taken from the same tree. Diameter, lenght, width and number of axial tracheids in 1 mm2, lumen widht, wall thickness, dimensions of bordered pit and porus number of rays, height and number of rays in 1 mm2 were analyzed statistically.

Tracheids in Scots pine, Black pine and Calabrian pine compressin wood were shortened approximately 10%, number of tracheids in 1mm2 were increased in different percentages, diameter of lumen and tracheid were not changed compared to normal wood. The tracheid diameter of early wood and late wood was given different results between species. It was seen that cell wall thickness only increased in Scots pine. Number of ray cell in compression wood which formed from Scots pine, Black pine were increased. Height of ray cell was increased only in Black pine. Also the diameter of bordered pits and porus in compression wood of Black pine and Calabrian pine were decreased, in contrast with Scots pine was not changed. It was also seen that crossing from early wood to late wood was very slowly and also significant cracks were seen on the tracheid walls of late wood.
