Relationships between microfibril angle, modulus of elasticity and compressive strength in Eucalyptus wood

Many traits are known to be important in determining the value of Eucalyptus wood as sawn timber. The commercial importance of the microfibril angle (MFA) for wood quality is well established for a range of softwoods, but is less clear for hardwood species. For instance, the relationships of MFA wit...
