Variation in mechanical and other wood properties between the two groups of sampled trees in the Flynn trial: earlywood and latewood in each ring. Microfibril angle (MFA), modulus of Elasticity (MOE) and wood density in wood cores from the 20 sampled trees were measured by SilviScan 2. Wood variation between the two groups of sampled trees was compared in earlywood (EW) (a) and latewood (LW) (b) of each ring for MOE, MFA and density. Error bars represent the standard deviation of the mean value of each trait. Variation in MFA and MOE is statistically significant (P-values ≤ 0.05) but it is not statistically significant for wood density variation in all rings.
