Summary
Morphactin IT3456, applied in a 2–3 cm band around the middle portion of 2- or 3-year-old internodes of artificially inclined 5-year-old Japanese larches, induced compression wood formation on both the upper and the lower sides of the inclined stem above the treated region, while it inhibited compression wood formation below this region. These results seem to suggest that a high concentration ratio of endogenous auxin to sugar (auxin/sugar) in the differentiating xylem tissue is necessary and sufficient for compression wood formation, and that compression wood formation under natural conditions requires polar transport of auxin which supplies and maintains high concentration of auxin along the undeside of the stem.
