In order to clarify the possibility of regeneration by seedlings the amounts of fallen nuts, cupules and litter and the survival of seedlings of Japanese beech (Fagus japonica) were studied in two sample plots (Fj-1 and Fj-2) of natural beech forests in the Chichibu Mountains, Central Japan, for three years (1988-1990). 2. The density of fallen nuts varied greatly from year to years from 943.93±144.00 nuts/m2 (1988) to 0.2±0.21 nuts/m2 (1989) in Fj-1 and from 907.11±150.26nuts/m2 (1988) to 0.22±0.29nuts/m2 (1989) in Fj-2. The figure in Fj-1 in 1988 was about three times higher than that of the former best mast year (OHKUBO et al. 1989). It was even higher than that of the highest record obtained in Siebold's beech (Fagus crenata) forests (KAMITANI et al. 1986).","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54996","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KAJI, Mikio"}]},{"nameIdentifiers":[{"nameIdentifier":"54997","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAWADA, Haruo"}]},{"nameIdentifiers":[{"nameIdentifier":"54998","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SASAKI, Kiyokuni"}]},{"nameIdentifiers":[{"nameIdentifier":"54999","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OHMURA, Kazuya"}]},{"nameIdentifiers":[{"nameIdentifier":"55000","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OHKUBO, Tatsuhiro"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学農学部附属秩父演習林"},{"subitem_text_value":"東京大学農学部林学科"},{"subitem_text_value":"宇都宮大学農学部森林科学科"},{"subitem_text_value":"University Forest in Chichibu, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"Department of Forest Science, Faculty of Agriculture, Utsunomiya University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"梶, 幹男"}],"nameIdentifiers":[{"nameIdentifier":"54991","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"沢田, 晴雄"}],"nameIdentifiers":[{"nameIdentifier":"54992","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐々木, 潔州"}],"nameIdentifiers":[{"nameIdentifier":"54993","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大村, 和也"}],"nameIdentifiers":[{"nameIdentifier":"54994","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大久保, 達弘"}],"nameIdentifiers":[{"nameIdentifier":"54995","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-09"}],"displaytype":"detail","filename":"esrh087003.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh087003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25487/files/esrh087003.pdf"},"version_id":"1eb1b0c8-746b-432a-81ab-a1140e73bd71"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"秩父","subitem_subject_scheme":"Other"},{"subitem_subject":"天然更新","subitem_subject_scheme":"Other"},{"subitem_subject":"イヌブナ","subitem_subject_scheme":"Other"},{"subitem_subject":"堅果","subitem_subject_scheme":"Other"},{"subitem_subject":"実生","subitem_subject_scheme":"Other"},{"subitem_subject":"Chichibu","subitem_subject_scheme":"Other"},{"subitem_subject":"Natural regeneration","subitem_subject_scheme":"Other"},{"subitem_subject":"Japanese beech","subitem_subject_scheme":"Other"},{"subitem_subject":"Nuts","subitem_subject_scheme":"Other"},{"subitem_subject":"Seedlings","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"秩父山地天然林の更新に関する基礎的研究1 : イヌブナ（Fagus japonica ＭAXIM.) 天然林における堅果落量と実生の消長","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"秩父山地天然林の更新に関する基礎的研究1 : イヌブナ（Fagus japonica ＭAXIM.) 天然林における堅果落量と実生の消長"}]},"item_type_id":"4","owner":"1","path":["2568","2567"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25487","relation_version_is_last":true,"title":["秩父山地天然林の更新に関する基礎的研究1 : イヌブナ（Fagus japonica ＭAXIM.) 天然林における堅果落量と実生の消長"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:52:24.626654+00:00"}
