The preliminary study of the lignin properties of Ulin revealed that the lignin of this wood primarily constitutes of guaiacyl lignin, notwithstanding the fact that the wood is a typical hardwood. The results of delignification process showed that at one hour delignification by chlorite treatment, the delignification rate of Ulin is extremely slower than those of Buna (Fagus crenata) and Sugi (Cryptomeria japonica). In order to get more information about the influence of lignin on the fungal attack on wood, a decay experiment on normal and delignified wood meals was conducted. The wood decay test showed that there is great differences in the weight loss of normal and delignified wood of Ulin after being exposed to the fungi for four months of incubation. The result of the present investigation indicated that the degree of lignin removal from wood by chlorite treatment is not closely correlated to the change in the weight loss after fungal attack.","subitem_description_type":"Abstract"},{"subitem_description":"ウリン材の大きな耐朽性の一因がリグニンにあると考えてその性状をブナ，スギと比べながら追求した．リグニン量はスギなみであったが，廣葉樹材であるのにグアイアシル基が過半をしめた。また亜塩素酸塩処理をしたときのリグニンの除かれ方がブナ，スギより著しく遅かった。0，1，2，3時間亜塩素酸塩処理した木粉夫々でカワラタケ，オオウズラタケを培養して木粉の重量減少を調べた。処理時間の長い木粉ほどリグニン含量は小さく，腐朽による重量減少は大きかったが，両者の間に強い相関は認められなかった。","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55358","nameIdentifierScheme":"WEKO"}],"names":[{"name":"シャフィー, ワスリン"}]},{"nameIdentifiers":[{"nameIdentifier":"55359","nameIdentifierScheme":"WEKO"}],"names":[{"name":"鮫島, 正浩"}]},{"nameIdentifiers":[{"nameIdentifier":"55360","nameIdentifierScheme":"WEKO"}],"names":[{"name":"善本, 知孝"}]}]},"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":"東京大学農学部林産学科"},{"subitem_text_value":"Department of Forest Products, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SYAFII, Wasrin"}],"nameIdentifiers":[{"nameIdentifier":"55355","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAMEJIMA, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"55356","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YOSHIMOTO, Tomotaka"}],"nameIdentifiers":[{"nameIdentifier":"55357","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":"esrh079005.pdf","filesize":[{"value":"556.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh079005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25551/files/esrh079005.pdf"},"version_id":"a4fe4e81-8ce9-4f47-afa0-c8776b9bf48e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ウリン材","subitem_subject_scheme":"Other"},{"subitem_subject":"脱リグニン","subitem_subject_scheme":"Other"},{"subitem_subject":"腐朽","subitem_subject_scheme":"Other"},{"subitem_subject":"耐朽性","subitem_subject_scheme":"Other"},{"subitem_subject":"担子菌","subitem_subject_scheme":"Other"},{"subitem_subject":"Ulin wood (Eusideroxylon zwageri)","subitem_subject_scheme":"Other"},{"subitem_subject":"Delignification","subitem_subject_scheme":"Other"},{"subitem_subject":"Decay","subitem_subject_scheme":"Other"},{"subitem_subject":"Durability","subitem_subject_scheme":"Other"},{"subitem_subject":"Basidiomycetes","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 Role of Lignin on Decay Resistance of Ulin (Eusideroxylon zwageri T. et B.) to Wood-rotting Fungi","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Role of Lignin on Decay Resistance of Ulin (Eusideroxylon zwageri T. et B.) to Wood-rotting Fungi"}]},"item_type_id":"4","owner":"1","path":["2584","2583"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25551","relation_version_is_last":true,"title":["The Role of Lignin on Decay Resistance of Ulin (Eusideroxylon zwageri T. et B.) to Wood-rotting Fungi"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:44.338277+00:00"}
