Diagram of the transverse sections isolated to represent normal, tension and opposite wood fractions. (A) Diagram of a transverse section of one of the three trees induced over 43 days by inclining. The two areas indicated by dashed lines represent the isolated tension wood and opposite wood fractions. (B) Diagram of a transverse section of one of the three control trees grown with the 43-day-treated trees. The single area indicated by the dashed line represents isolated fraction equivalent to reaction wood.
