| Outline of Final Research Achievements |
The species and spatio-temporal distribution of Neolithic edible bulbous plants (scales) were elucidated. We conducted carbonization and cooking experiments to identify carbonized scales attached to pottery from the Jomon and Yayoi periods in the Japanese archipelago and the Neolithic period in the Korean peninsula. We identified pottery indentation scales and carbonized scales as Barnardia japonica.
We confirmed that Barnardia japonica was used since the early Jomon Period and
continued to be used until the middle Yayoi Period on the Honshu Island eastward to the Kanto Region and on the Korean Peninsula. Although bleaching is required to remove astringent contents, Barnardia japonica bulbs were one of the important food resources processed with earthenware in the Neolithic period in Japan and Korea. Moreover, we have revealed that two kinds of bulbs of Allium macrostemon and Barnardia japonica occur in the earthenware impressions.
