Large numbers of tropical trees from natural forests or plantation forest are available for human consumption and management. This book focuses on the prospects and utilization of tropical plantation trees in context of economic and business, planting, managing stocks, and uses of trees converted to various wood-based products. It provides information on key areas of tropical plantation trees including growth performance, nursery practices, soil properties, planting stock production, raw material cellulose, anatomy, pulping and papermaking, fiber modification, and properties of wood composites. Features: Comprehensive information on prospects and utilization of tropical plantation tree species. Features information on potential products derived from tropical plantation trees including cellulose-based wood products, particleboard with bioplastic binder, and laminated veneer lumber. Discusses species usage of economic importance other than wood production. Presents information on nursery practices, growth performance, and soil properties of tropical trees. Illustrates methodologies for repeating investigations on work that has been done previously in tropical tree research. This book introduces information for entrepreneurs or researchers before undertaking work with these tree species illustrating technical methodologies allowing for repetition or previous successful works. This information proves valuable to researchers if further work is needed for improvement on these plant-derived products.

Acacia hybrid from plantation was divided into bark, sapwood and heartwood. Each portion undergone Soxhlet extraction according to ASTM D1108-96, D1107-96 and D1110-84 using different polarity solvents; hexane, methanol and hot water. The crude extract of each portion was analyzed to determine its chemical components of wood extractives from the extraction solvents. Wood extractives covered in this study were low molecular weight compounds; fatty acids, sterols, glycerides and steryl ester. Gas chromatography analysis was carried out for crude extract of hexane and methanol due to these volatile solvents. Crude extract of hot water was analyzed by High Performance Liquid Chromatography due to its non-volatility. Results shown that total extractives analyzed by Gas chromatography for methanol extract in heartwood was highest, 1.45 mg/g, followed by bark and sapwood of 1.39 mg/g and 0.89 mg/g respectively. For hot water extract, heartwood was found to have the most in total extractives, 1.83 mg/g, followed by bark 1.26 mg/g and sapwood, 0.82 mg/g.
Laminated veneer lumber is a product made from pieces of veneers put together on top of each other with their grains aligned parallel to each other and then glued together. This simple step-by-step illustrated guide book could be used by students in their learning or even researchers to conduct their experiments or research works. With the many images presented, it would help people with little knowledge of making laminated veneer lumber on a laboratory scale to make one themselves. The processes described in this guide start from harvesting of logs, preparing them for peeling into veneers, drying, cutting test pieces from the fabricated laminated veneer lumber for physical and mechanical testing according to different standards, conducting the testing and calculating the data obtained from the testing.
