| Research Abstract |
1. There were mixed type of forest of laurel forest and cool temperate deciduous broad-leaved forest during Middle Jomon to Late Jomon Period at central Honshu from Kyoto Pref.to Shiga Pref. Quercus gilva and Aesculus turbinata were nuts food in this area.
2. First usage of Aesculus turbinata seed was recorded from Awazu kotei site, Siga Pref.at Middle Jomon Period. It started at the distributional margin of Aesculus turbinata rather than its center. Major food was shifted from Quercus gilva to Aesculus turbinata within the shell mound.
3. Fruits size of Castanea creanta is enlarged during the Jomon Period. It was the same size as the wild type at the Earliest Jomon Period, enlarged since Early Jomon Period, and as large as the modern cultivated type at Late and Latest Jomon Period.
4. Secondary forest of Castanea crenata is maintained for 1000 years during the Early Jomon Period, at Sannai Maruyama Site, Aomori. Major nuts food were Castanea crenata and Juglans sieboldiana at that time. Herbaceous crops seems to be used but was not common.
5. Castanopsis cuspidata has two varieties in Japan. And one varieties has sometimes regarded as a cultivated type. Based on the plant macrofossil data, this hypothesis is denied.
6. Data base of the plant macrofossils of the Jomon Period is made as basal data.
