| Popis: | Pinus halepensis Mill. was introduced into regions with a Mediterranean cli- mate as an ornamental tree, and is now often found in parks and gardens. At pre- sent, Aleppo pine (Pinus halepensis Mill.) forests cover approximately 2,500,000 ha in the Mediterranean Basin, mostly at low altitudes (less than 500 m) and along the coast. It has become naturalized outside cities in North Africa to the extent that it is now listed as an invasive species there. Because of its size (over 15 m in height and 30 cm in diameter), Pinus hale- pensis could be a good potential green resource for structural material in Tunisia. The focus of this study was to assess rot resistance and the physical and mecha- nical properties of reforestation Aleppo pine from the Mediterranean basin. The Pinus halepensis wood samples studied were collected from 6 tree provenances in Tunisia for physical and mechanical characterization and from Morocco for decay and termite resistance tests. Den- sities and shrinkage were determined and mechanical and rot resistance tests performed. Preliminary results showed that Tunisian Pinus halepensis wood has great dimensional stability. Although the compressive strength of Pinus halepen- sis wood is high, its bending strength is rather low for each of the provenances. MOR in bending is lower than in other Tunisian softwood species. Finally, Pinus halepensis sapwood has low resistance to fungi and termites. This timber species could be valuable for furniture and/or as a building material provided that a wood preservation method is applied before it is used. |
