The short rotation trees had longer fiber length, higher slenderness ratio, flexibility coefficient and lower Runkel ratio and rigidity coefficient with higher proportion of holocellulose content acceptable lignin, ash and pentasons. These preporties directly related to the high burst strength, tensile strength, tearing strength and folding endurance of the paper. The greatest proportion of fiber length in M. dubia (1022.36μm) and the lowest in Eucalyptus clones (538.80μm). The higher content of holocellulose in A. fraxinifolis (74.2%), P.deltoides (74.15%) and M.dubia (74%) species were recorded and significantly low value in L. leucocephala (70.81%). So, the short rotation trees were more preferable for paper production based on the morphological and chemical properties.
