Blockage of sap-flow occurred around the inoculation point, and this phenomenon is considered to be the direct cause of tree's death.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54224","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMATO, Mariko"}]},{"nameIdentifiers":[{"nameIdentifier":"54225","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMADA, Toshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"54226","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Kazuo"}]}]},"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":"東京大学大学院農学生命科学研究科森林植物学研究室"},{"subitem_text_value":"Laboratory of Forest Botany, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大和, 万里子"}],"nameIdentifiers":[{"nameIdentifier":"54221","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田, 利博"}],"nameIdentifiers":[{"nameIdentifier":"54222","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 和夫"}],"nameIdentifiers":[{"nameIdentifier":"54223","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":"esrh106004.pdf","filesize":[{"value":"854.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh106004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25350/files/esrh106004.pdf"},"version_id":"7ccf6358-481a-4c1a-9b31-8712c643e00e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ナラ類","subitem_subject_scheme":"Other"},{"subitem_subject":"萎凋","subitem_subject_scheme":"Other"},{"subitem_subject":"通水阻害","subitem_subject_scheme":"Other"},{"subitem_subject":"カシノナガキクイムシ","subitem_subject_scheme":"Other"},{"subitem_subject":"ナラ菌","subitem_subject_scheme":"Other"},{"subitem_subject":"oaks","subitem_subject_scheme":"Other"},{"subitem_subject":"wilt","subitem_subject_scheme":"Other"},{"subitem_subject":"blockage of xylem sap ascent","subitem_subject_scheme":"Other"},{"subitem_subject":"Platypus quercivorus","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":"ナラ類の萎凋枯死と通水阻害","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ナラ類の萎凋枯死と通水阻害"}]},"item_type_id":"4","owner":"1","path":["2530","2529"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25350","relation_version_is_last":true,"title":["ナラ類の萎凋枯死と通水阻害"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:39.756339+00:00"}
