Outline of Final Research Achievements

Analysis of the diversity and phylogenetic relationships of Metroxylon palms in Oceania based on the 5S nr DNA sequence revealed that Vanuatu sago palm (M. warbrugii) was the second most diverse after sago palm (M. sagu). From the analysis using MaxEnt, in order to reduce the risk of endangered Fijian sago palm (M. vitiense), transplantation to potential suitable places in the inland where suitable habitats exist as well as coastal areas will be important as a conservation strategy. Considering the change in climate, it is estimated that the future suitable land for growth of M. vitiense will increase two to four times. In comparison of agronomic traits revealed that sago palm has a high productivity due to its high dry matter content in the pith and starch concentration, while the growth rate of Solomons’ sago palm (M. salomonense) is considered to be high.

Academic Significance and Societal Importance of the Research Achievements

サゴ属植物は問題土壌に適応して多量の澱粉を生産できるため,食料,生物燃料資源として期待される。大洋州では主食,建築資材や工芸品の原材料として伝統的に幅広く利用されてきが,一部地域ではコミュニティーでの情報の伝承が不十分となり,レリクトクロップになりつつあるところもある。また,従来は収穫のほとんどを自然林から得てきたサゴ属資源であるが,今後は,地域資源の保全を前提とした持続的利活用を推進する必要がある。本研究で得られたサゴ属の遺伝的多様性,資源量の把握と将来予測,農業形質に関する成果は,植物保全による資源量の維持,生産の安定化,至適な利用,二次製品の開発方針などの検討に資するものと考えられる。
