The relationships between the stem inclination and (A) width of the current growth layer on the lower side of the inclined stem, (B) percentage of cell wall in cross-section, (C) microfibril angle (MFA) and (D) Klason lignin content. Each symbol indicates the mean of five saplings, except for MFA in which it denotes the mean of 30 tracheids. Error bars indicate s.d. Different letters denote significant differences. The absence of letters indicates that no significant differences were observed.
