| Research Abstract |
In ring-porous hardwood species, we detected dramatic changes in IAA levels in the region of the cambial zone and its derivatives accompanying winter-bud break. Localized temperature controlling on the stem surface succeeded in inverting order between re-initiation of vessel formation in the treated portions and winter-bud break in hardwoods. In a diffuse-porous hardwood species, in which winter-bud broke prior to vessel formation, localized heating induced specific wood structures in xylem formed before the bud break.
