| Outline of Final Research Achievements |
In this study, physiological and ecological field survey and genetically analysis were conducted on Avicennia Marina, native to the Red Sea coast. As a result, it was recognized that A.Marina adjusted the amount of leaves by browsed by livestock, for example by camels, maintaining the forest area without great death in the dry year. We also found that the adventitious roots were elongated by implanting laterally extending branches and the possibility of maintaining the tree morphology even under high salinity conditions was confirmed by distributing the water from the roots to the tip of shoot. In addition, the genetic diversity in the Red Sea was not high, which was thought to be due to the influence of the seed spreading pattern. The possibility of being affected by artificial gene transfer was recognized depending on the location, and trading from ancient times was thought to have influenced the genetic diversity of A.Marina.
