Among the wood samples tested, the lignin of Ulin wood (Eusideroxylon zwageri), Bangkirai (Shorea laevis), Koki (Hopea pierrei), and Malas (Homalium foetida), are primarily constituted of guaiacyl units, notwith-standing the fact that the wood are typical hardwoods. To assess the influence of lignin structure on the rate of decay, these peculiar hardwoods were then subjected to decay by C. versicolor. From the present investigation it can be interpreted that the hardwoods containing guaiacyl-rich lignin are more resistant than those of hardwoods containing syringyl-rich lignin.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55274","nameIdentifierScheme":"WEKO"}],"names":[{"name":"シャフィー, ワスリン"}]},{"nameIdentifiers":[{"nameIdentifier":"55275","nameIdentifierScheme":"WEKO"}],"names":[{"name":"善本, 知孝"}]},{"nameIdentifiers":[{"nameIdentifier":"55276","nameIdentifierScheme":"WEKO"}],"names":[{"name":"鮫島, 正浩"}]}]},"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":"東京大学農学部材産学科"},{"subitem_text_value":"Department of Forest Products Technology, Faculty of Forestry, Bogor Agricultural University, PO BOX 69, Bogor, Indonesia"},{"subitem_text_value":"Department of Forest Products, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SYAFII, Wasrin"}],"nameIdentifiers":[{"nameIdentifier":"55271","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YOSHIMOTO, Tomotaka"}],"nameIdentifiers":[{"nameIdentifier":"55272","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAMEJIMA, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"55273","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":"esrh080004.pdf","filesize":[{"value":"619.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh080004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25536/files/esrh080004.pdf"},"version_id":"1365f38e-8831-4e28-878e-3337e1a19c9d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Delignification","subitem_subject_scheme":"Other"},{"subitem_subject":"Basidiomycetes","subitem_subject_scheme":"Other"},{"subitem_subject":"Decay","subitem_subject_scheme":"Other"},{"subitem_subject":"Guaiacyl-rich lignin","subitem_subject_scheme":"Other"},{"subitem_subject":"Syringyl-rich lignin","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"The Effect of Lignin Structure on Decay Resistance of Some Tropical Woods","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Effect of Lignin Structure on Decay Resistance of Some Tropical Woods"}]},"item_type_id":"4","owner":"1","path":["2582","2581"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25536","relation_version_is_last":true,"title":["The Effect of Lignin Structure on Decay Resistance of Some Tropical Woods"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:45.216828+00:00"}
