(Yezo spruce) is one of the most important trees. However, natural regeneration of Yezo spruce in the forest depends on the presence of particular natural regeneration sites, for example, fallen decaying trees, which presents some problems for the nursery breeding and man-made reforestation of this species. Moreover, this species was greatly overcut at the time of World War II. Therefore, there is anxiety for its continued use as a resource in Hokkaido. Thus, the establishment of techniques for man-made reforestation and promotion of natural regeneration of this tree are urgent problems still awaiting solution in Hokkaido.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55048","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKAHASH, Ikuo"}]}]},"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北海道演習林"},{"subitem_text_value":"University Forest in Hokkaido, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 郁雄"}],"nameIdentifiers":[{"nameIdentifier":"55047","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":"esrh086006.pdf","filesize":[{"value":"7.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh086006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25496/files/esrh086006.pdf"},"version_id":"0f7e942a-6841-49a2-bdff-bb40e04d27fc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"エゾマツ","subitem_subject_scheme":"Other"},{"subitem_subject":"外生菌根菌","subitem_subject_scheme":"Other"},{"subitem_subject":"倒木腐朽","subitem_subject_scheme":"Other"},{"subitem_subject":"天然更新","subitem_subject_scheme":"Other"},{"subitem_subject":"特殊更新立地","subitem_subject_scheme":"Other"},{"subitem_subject":"Yezo spruce","subitem_subject_scheme":"Other"},{"subitem_subject":"Ectomycorrhizal fungus","subitem_subject_scheme":"Other"},{"subitem_subject":"fallen decaying tree","subitem_subject_scheme":"Other"},{"subitem_subject":"natural regeneration","subitem_subject_scheme":"Other"},{"subitem_subject":"particular regeneration site","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":"エゾマツの生育過程と菌類相の遷移 : 特に天然更新に対する菌類の役割","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"エゾマツの生育過程と菌類相の遷移 : 特に天然更新に対する菌類の役割"}]},"item_type_id":"4","owner":"1","path":["2570","2569"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25496","relation_version_is_last":true,"title":["エゾマツの生育過程と菌類相の遷移 : 特に天然更新に対する菌類の役割"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:42.534712+00:00"}
