We investigated wood properties and variations in the stems of 10- and 16-year-old Melia azedarach trees of three clones (Type 1, Type 18, and M-type), to explore the potential of this species. All three clones had straight stems due to bud pruning. Diameter at breast height ranged from 21.9-24.8 cm in 10-year-old trees and 23.1-31.2 cm in 16-year-old trees. There were significant differences among clones in air-dry density, modulus of elasticity (MOE), and modulus of rupture (MOR) at 10 years, whereas at 16 years, air-dry density, MOE and MOR generally increased from the pith outward in all trees, regardless of elevation, but there were no significant changes in mean values by height. In the early stages of growth, air-dry density, MOE, and MOR were lower at lower elevations, but differences may have been less significant at lower heights because the lower the height, the better the growth of this species. Production targets were set at 30 cm for top end diameter and 4 m straight length, suggesting the possibility of harvesting materials from trees with similar heights, despite other differences, if trees attain target sizes.
