| Research Abstract |
In flooded roots of Melaleuca cajuputi, a tree species in tropical swamps, lower allocation of sugars to body constitution and their higher allocation to energy metabolism allowed high energy status. The manner of changes in sugar allocation was different between two kinds of seedlings with different growth stages. When flooded conditions were prolonged, lacunae formed in stem and roots mitigated oxygen shortage in roots. In addition, it was found that M. cajuputi has mitochondria that can generate ATP under anaerobic conditions.
