Abstract
Aboveground- tree biomass and mechanical wood properties were measured in 36- year- old trees of Khaya senegalensis A. Juss. either as an experimental area or as a single- tree row, grown on infertile soil in the Tropical Farm of Kom- Ombo, Aswan Botanical Garden, Hort. Res. Inst., Agric. Res. Center, Egypt. Khaya senegalensis grown as a single row had the highest values of total stem volume, diameter at breast height and merchantable height as well as weights of leaves, twigs up to 1 cm diameter and branches up to 5 cm diameter compared to that grown in plantations at 5x5 m spacing. Data revealed that, the productivity potential of 36-year- old Khaya senegalesnis grown under Aswan conditions at 5x5 m spacing was about 300.7 m3/ fed, 61.8 ton/ fed, 61.9 ton/ fed and 34.3 ton/ fed for the total stem volume, branches up to 5 cm diameter, twigs up to 1 cm and fresh leaves, respectively. On the other hand, the mechanical properties of Khaya senegalensis planted in this region were comparable of a number of valuable hardwood species grown in different countries. Khaya senegalensis as plantations in this study showed a high potential for producing wood with higher values for modulus of rupture (MOR), modulus of elasticity (MOE), compression parallel to grain and maximum shearing of strength than that of trees in a single row.
