Résumé : Due to its outstanding properties, teak (Tectona grandis Linn. f.) is one of the most desirable tropical timbers in the world. For this reason, and due to the depletion of its natural stands, teak is increasingly coming from plantations, using much shorter rotations. Teak plantations were first established successfully in Togo in 1920, and have been widely established throughout the tropics. However, no studies have examined differences in the quality of Togolese teak cultivated in Togo's different ecological zones. The proportion, modulus of elasticity, and basic density of heartwood in 80 trees of various ages grown in different ecological zones in Togo was examined. The results show that the percentage of heartwood in trees differs significantly, depending on the ecological zone in which they grow. Basic density was significantly correlated with age, while the longitudinal modulus of elasticity at 1.30 m was found to be similar in both juvenile and adult heartwood. (Texte intégral)
