The BWD showed a similar trend at each site in that density was initially decreased then increased with increasing height position. For fiber traits, the fiber length (FL) decreased linearly with the height of the trunk, whereas fiber width and coarseness changed relatively slightly with increasing height position. In addition, the vertical wood properties distribution patterns were different from clones so that some clones showed more markedly change in height positions than others. The joint analysis indicated significant height position effect for BWD and fiber traits, in accordance with site and clonal effect. Significant site × height interaction was found on wood properties, whereas the significant clone × height interaction was only obtained at fiber width. Moreover, variation in the relationships between FL and BWD or other fiber traits showed no consistent pattern with increasing height position.Read More
