Results indicate that A. crassicarpa is of the greatest average fiber length and A. mangium is of the greatest average vessel length, which are 1 179.6 um and 333.1 um, respectively. Fiber morphology of all 4 acacia species accords with the requirement on pulping and paper-making, so the 4 acacia timbers can be used for pulpwood, A, cincinata is of the greatest air-dry density 721 kg/m^3 and greatest basic density 617 kg/m^3, however, A. mangium is of the best dimensional stability because of its smallest coefficient of shrinkage. With the highest value of every index, A. cincinata is of the best mechanical properties.展开更多
