  1. Mean values of tested wood properties for the sample types. Standard errors are in brackets. The reported standard deviation for the micro-fibril angle (MFA) is the value of the standard deviation parameter fitted to the model used to describe the micro-fibril spread around the mean (Cave and Robinson 1998a; 1998b)
