| Research Abstract |
The changes in water distribution of vessels and sap flow velocity under continuous drought and following irrigation were examined in the invasive species in the Bonin Island. The relationships between wood anatomical parameters and functional types were also tested using analysis of principal component in several species which grow in the mesic or xeric site in the islands. Water use in Bischofia javanica, which invade mesic site, was not effective to sudden water supply. In contrast, Psidium cattleianum, which invade xeric site, could use water more effective than indigenous species in sudden precipitation. The construction of network across xylem conduits and rays is one of the contributing factor to determine the traits of water use of these species.
