Outline of Final Research Achievements

In the Ogasawara Islands, a World Natural Heritage site, we have made noteworthy observations on tree mortality, which can be attributed to many causative factors, such as seed masting, drought, salinity damage due to a big typhoon, and the infection of southern root rot disease. Here, we have attempted to elucidate the physiological mechanisms that cause tree mortality and proposed a "tree mortality model. In this model, the physiological process of tree death is a negative spiral, in which stomatal closure and photosynthesis are reduced, sugar transport to the root system through the sieve is inhibited, and the root system declines, which leads to further reduction in water absorption, further reduction in photosynthesis, and reduction in sugar storage, which ultimately results in death from sugar deficiency. We thus support "carbon starvation hypothesis", which ultimately results in tree death from the deficiency of stored carbohydrates.

Academic Significance and Societal Importance of the Research Achievements

近年温暖化により、旱ばつや熱波による樹木枯死、森林衰退が世界各地のバイオームで起きている。森林の衰退予測や劣化した森林の修復のため、樹木の乾燥枯死の生理メカニズムの解明が世界的にも喫緊で重要な課題になっている。樹木の乾燥枯死の生理メカニズムとして、木部道管の水切れの進行による「通水欠損仮説」と、気孔閉鎖に伴う光合成低下による「糖欠乏仮説」の二つ仮説が対立して論議されているが、未だ結論は得られていない。この課題で小笠原の亜熱帯林を舞台に、上記二つの仮説における水利用と糖獲得といった密接に相互関連した二つの生理過程を包含した「樹木枯死の統合モデル」の提唱を行ない、被引用数も増加している。
