Research Abstract

Tree vigor diagnosis is essential for growing healthy trees as well as safety management of preventing trees from falling. This research aimed at developing practical and objective tree vigor diagnosis based on delayed fluorescence measurement. As a result, it was newly found that amount of delayed fluorescence from initiation of measurement to several seconds increase when a tree is exposed to drought stress and that this increase of delayed fluorescence may be an effective indicator of tree vigor diagnosis.
