  1. Mean values and standard deviation are given for d = diameter (mm), I = Second moment of area (mm4) and E = Young’s bending modulus (N/mm2) across all replicates per treatment with the given sample sizes n and p-values were derived with a 2 sample t-test. Differences that are statistically significant at the 5% level are displayed in bold.
