Hondai) is frequently observed in heavy snowfall regions as well as the northern part of Japan. Reforestation with Hinoki has become so widespread that the pitch canker is becoming one of the most serious disease. Empirically, the \"Rooshi\" pitch canker of Hinoki is supposed to be one of the restriction factors on natural distribution of Hinoki forest in Japan. However, there are few scientific papers on the disease. The cause of the disease has not been explained enough. From our survey, the \"Rooshi\" pitch canker is considered to be a disease complex rather than a discrete canker disease. The classic symptoms of the disease are classified into three types, that is, a bleeding type, a resinous sink type, and a grooved pitch canker type on the trunk of living tree. In this study, we discussed on the mechanisms of the development of \"Rooshi\" pitch canker. A bleeding type is supposed to be an incipient stage of \"Rooshi\" pitch canker and caused by abiotic stress factors such as cold and snowfall. This incipient stage of the disease develops to a resinous sink type on the trunk. And, finally, a grooved pitch canker is formed on the trunk accompanying fungi such as Sarea resinae and Pezicula livida (Cryptosporiopsis abietina).","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55259","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Kazuo"}]},{"nameIdentifiers":[{"nameIdentifier":"55260","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUKUDA, Kenji"}]},{"nameIdentifiers":[{"nameIdentifier":"55261","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KAJI, Mikio"}]},{"nameIdentifiers":[{"nameIdentifier":"55262","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KAMITANI, Tomohiko"}]}]},"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":"東京大学農学部林学科"},{"subitem_text_value":"新潟大学農学部林学科"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, University of Tokyo"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, Niigata University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鈴木, 和夫"}],"nameIdentifiers":[{"nameIdentifier":"55255","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福田, 健二"}],"nameIdentifiers":[{"nameIdentifier":"55256","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶, 幹男"}],"nameIdentifiers":[{"nameIdentifier":"55257","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"紙谷, 智彦"}],"nameIdentifiers":[{"nameIdentifier":"55258","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":"esrh080001.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh080001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25533/files/esrh080001.pdf"},"version_id":"87ed21e7-58a2-47e1-877d-e4a082fa797a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ヒノキ","subitem_subject_scheme":"Other"},{"subitem_subject":"ヒノキアスナロ","subitem_subject_scheme":"Other"},{"subitem_subject":"漏脂病","subitem_subject_scheme":"Other"},{"subitem_subject":"発生機序","subitem_subject_scheme":"Other"},{"subitem_subject":"複合病害","subitem_subject_scheme":"Other"},{"subitem_subject":"Chamaecyparis obtusa","subitem_subject_scheme":"Other"},{"subitem_subject":"Thujopsis dolabrata var.
