  1. aASL, acid-soluble lignin; AIL, acid-insoluble lignin; DM, dry matter; DCB, 2,6-dichlorobenzonitrile. Data represent mean stem biomass composition with standard error of the mean shown in parentheses. For control, n = 6 for tension wood, DCB-treated, and DCB-treated, tension wood-induced trees in the 26-day treatment group; for debarked control, n = 3 for isolated tension wood and isolated opposite wood 43-day treatment group. Unaccounted for mass is recognised here as Other.
