Outline of Final Research Achievements

Eurya japonica Thunb. (Theaceae) and Ligustrum japonicum Thunb. (Oleaceae) inhabit special environments such as riverside and serpentine areas. Therefore, to compare their morphological and anatomical adaptation into these environments could lead to find out the common process in woody plants. The aim of this study is to clarify morphological and anatomical traits of them. As a result, both species in riverside areas had common changes such as leaf dwarfing, leaf thickening, the decreasing cell number, and the increasing stomatal density, and they serpentine areas had the common such as leaf thickening and the deducing stomatal size. From these results, it was shown that E. japonica and L. japonicum had changed their morphology and cells according to different environments, and it was able to find the common process regarding environmental adaptation of woody plants.

Academic Significance and Societal Importance of the Research Achievements

本研究は、特殊環境に生育するための植物の変化を示すことが出来るために、植物の多様化を形成する特殊要因と共通要因を明らかにすることが出来るために、そのような環境の保全を推進する際に非常に有用な研究成果となり、学術的だけではなく社会的意義は高い。
