| Outline of Final Research Achievements |
Cinnamomum camphora has long been utilized by human-beings, which makes the natural geographic distribution of this tree unclear. The genetic analysis and field survey revealed that Japanese C. camphora populations held unique genetic composition and regeneration ability, but their genetic diversities were less than half those of Chinese and Taiwanese populations probably because of post-glacial bottleneck events. It should be noted that several individuals less than 100 cm of diameter at breast height were genetically admixed between regions (Japan vs. China and Taiwan), indicating the occurrence of human-induced genetic contaminations over several decades.
