    ほとんどの樹種において幹や枝の中心部に心材と呼ばれる特殊な部分が形成される。心材の形成は、木材科学における普遍的・基盤的な重要事項であると共に、色調・におい・耐久性等に優れる木材の生産の観点から林業にも関連する。しかしながら心材形成機構には不明な点が多い。
    本研究では、心材の元となる生きた辺材を用い、樹木(辺材)齢と栄養物質・植物ホルモンの投与を様々に組み合わせることにより、心材形成の人為的誘導実験系の構築を目指す。この誘導期間における化学成分変化ならびに細胞組織変化を経時的に追跡し、これらを関連付けることにより、どのようにして心材形成が開始され進行するのか、などに関して知見を取集する。

    The commercial values (color tone) of Cryptomeria japonica wood are affected by characteristics of the heartwood (HW, dark part at the central part of the wood) which are formed from the sapwood (SW, pale part surrounding heartwood) via intermediate wood (IW) with growth of the trees. The change from SW to HW via IW are called HW formation. In the HW formation of C. japonica, (1) what sort of compounds were formed, (2) how the compounds were formed (formation mechanism), and (3) where the compounds were synthesized at cellular level (synthesis site), were studied.
    (1) Several kinds of new compounds were successfully isolated and their chemical structures were elucidated. The contents and distribution of these compounds in normal red-HW were different from those in abnormal black-HW. (2) It was demonstrated that these compounds were formed by oxidase enzymatic reaction in the HW and IW. (3) It was visualized the enzymatic reaction occurred in the ray parenchyma cells in the HW and IW.
