Outline of Final Research Achievements

The following new findings were obtained regarding the cambium activity and wood structures of Ginkgo biloba. (1) There will be cells peculiar to Ginkgo biloba that do not have pits and do not contribute to water flow. (2) The water flow pattern of ginkgo would be different from these of general conifers and broad-leaved trees. (3) It takes more than one month from the resumption of cambium activity to the completion of the first tracheid differentiation of the year and the increase in cell division frequency.
These characteristics are commonly recognized in different habitats (Akita prefecture, Miyazaki prefecture, Hokkaido, Tokyo), and are considered to be the unique and tree-specific characteristics of Ginkgo biloba.

Academic Significance and Societal Importance of the Research Achievements

本研究の実施により、イチョウの形成層活動の特異性が明らかになった。この結果は、本研究の目的であるイチョウを利用した地球温暖化広域モニタリングの可能性を示唆するものと考えられる。
また、これらの知見をもとに木本植物を対象とした進化と環境適応性に関する新たな研究が立ち上がるなど、今後の研究の進展が期待される。
