The results showed that the sawing strain changed in a random way, but the bow deformation had an evident regularity, the lumber near its bark had a big bow deformation. The end-splits had severe influence to lumber recovery, 15% of lumber recovery was influenced by end-splits. The results also indicated that planted E. grandis was a potential wood species as solid wood utilization in the fast-growing plantation.展开更多
