Propri�t�s physiques du bois d'�claircie des c�dres (Cedrus atlantica), contenant du bois de compression, provenant de l?Atlas du Djurdjura (Alg�rie)

Abstract: Résumé -Le bois du cèdre de l'Atlas (Cedrus atlantica Manetti) provenant de la cédraie du Djurdjura central, en Algérie, a fait l'objet d'une étude par une méthode destructive dans trois stations. Ces dernières se singularisent du point de vue de la densité du peuplement, l'exposition et la nature du sol. Au total 54 jeunes arbres (32 à 48 ans ; 4,5 à 7,9 cm de diamètre ), soit 18 arbres par station ont été prélevés. Les essais physiques entrepris sur 486 éprouvettes normalisées, soit 9/arbre sont : l'humidité… Show more

“…In terms of radial growth, the results support those announced above and show that growth rate of this planted cedar plots is similar to those from others native cedar forest. Indeed, for the trees planted during the 1970s, the average radial growth fluctuates between 2.9 and 8.2 mm/year is closed to those of humid cedar forests in the Rif in Morocco (3 to 8 mm/year) and are considerably higher than those of southern cedar forest in Morocco (0.8 -3.5) and Algeria (0.62 -1.14 mm/an) (Messaoudène et al 2004). Moreover, the mean of yearly radial growth (4.8 ± 1.05 mm) is very close to that of reforestation achieved during the same period (5.36 ± 1.5) (Sbabdji et al 2015) in Chrea area, where the cedar finds its best climatic conditions (more than 1000 mm/year) (Meddour 2002;Harfouche & Nedjahi 2003).…”

“…For those numerous advantages; cedar is designed by many authors (M'Hirit 1999;Harfouche & Nedjahi 2003) as a main species for the mountains reforestation, above 1000 to 1200 m altitude, and for the valorization of unproductive or damaged forest under Mediterranean climate. In the same context, Messaoudène et al (2004) indicate that the cedar forest in Algeria occupies 20,000 ha, but its climatic area is larger.…”

“…Par comparaison avec quelques cédraies méditerranéennes adultes, les largeurs moyennes des cernes des reboisements étudiés sont plus larges qu'aux Belezma, Theniet El Had et Djurdjura (Loukkas, 2001 ;Messaoudene et al, 2004 ;Sarmoum, 2008), au mont Ventoux (France) (Guibal, 1984), au Maroc (Till, 1986), ou dans les arboretums Photo 5.

“…Le cèdre de l'Atlas, Cedrus atlantica (Endl.) Carrière, est une essence qui a toujours suscité un grand intérêt en raison de ses nombreuses qualités forestières telles que son intérêt écologique, sa faible inflammabilité, sa production de bois de qualité, sa croissance juvénile appréciable, sa tolérance face aux stress climatiques et son intérêt paysager (Toth, 1978 ;Nedjahi, 1987 ;Yahi, 2007 ;Messaoudene et al, 2004). Cette essence est particulièrement recherchée pour son bois noble, facile à travailler, résistant aux adversités, au parfum doux, chaud et gardant son empreinte durant des millénaires.…”
