| Abstract | ||||
| Aboveground-tree biomass and some wood properties (specific gravity, moisture content, extractive content, cellulose, hemicellulose, holocellulose and ash content) were measured in 30-year-old of two tree species: Chrysophyllum oliviforme L. and Tamarindus indica L., growing on infertile soils as single row at 5m spacing for each species in the Tropical Farm, Kom- Ombo, Aswan Botanical Garden. Biomass and wood properties of the two species were similar to those reported for other tropical tree plantations in the same region. T. indica had the highest accumulation of aboveground tree biomass, in term of stem fresh and dry weight, branches fresh weight, leaves fresh weight and total biomass. However, C. oliviforme had the highest average of specific gravity, cellulose, hemicellulose and holocellulose contents of wood, while T. indica had the highest wood moisture, extractive and ash contents. Moreover, regarding the effects of bole heights on wood constitutes, there were significant differences between height treatments on wood properties of the two species. Diameter at breast height (dbh) and 0.75 of the total height showed a high potential for producing a best wood constitutes due to its more even distribution in this heights compared to 0.25 or 0.50 of the total height . | ||||
