It is considered that water stress plays an important role in the disease development. And, severity of water stress in pine trees is generally influenced by macro-climatic weather conditions. However, micro-climatic conditions such as incidence of gaps or openings of forest canopy seem to have some effects on the development of the disease. Tocompare physiological status of gap-faced trees, edge trees and trees in closed stand, water potentials were measured by a pressure chamber technique, and their components were determined by means of pressure-volume analysis. Diurnal patterns of water potentials and P-V curves obtained indicate remarkable differences in water status among pine trees measured. The results suggest \"gap-effect\" plays an important role on the development of the pine wilt disease in forest stands.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55346","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIMIZU, Ichiro"}]},{"nameIdentifiers":[{"nameIdentifier":"55347","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Kazuo"}]},{"nameIdentifiers":[{"nameIdentifier":"55348","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUKUDA, Kenji"}]}]},"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":"現勤務先：林野庁"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, University of Tokyo"},{"subitem_text_value":"Present address: Forestry Agency"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"清水, 一郎"}],"nameIdentifiers":[{"nameIdentifier":"55343","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 和夫"}],"nameIdentifiers":[{"nameIdentifier":"55344","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福田, 健二"}],"nameIdentifiers":[{"nameIdentifier":"55345","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":"esrh079002.pdf","filesize":[{"value":"430.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh079002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25548/files/esrh079002.pdf"},"version_id":"0acab219-d684-44cd-bdcd-c247df41cd83"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"材線虫病","subitem_subject_scheme":"Other"},{"subitem_subject":"水分生理状態","subitem_subject_scheme":"Other"},{"subitem_subject":"ギャップ効果","subitem_subject_scheme":"Other"},{"subitem_subject":"P－V曲線","subitem_subject_scheme":"Other"},{"subitem_subject":"pine wilt","subitem_subject_scheme":"Other"},{"subitem_subject":"water status of pines","subitem_subject_scheme":"Other"},{"subitem_subject":"gap-effect","subitem_subject_scheme":"Other"},{"subitem_subject":"pressure-volume analysis","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":"材線虫病の病微進展に及ぼす環境の影響 : ギャップ効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"材線虫病の病微進展に及ぼす環境の影響 : ギャップ効果"}]},"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":"25548","relation_version_is_last":true,"title":["材線虫病の病微進展に及ぼす環境の影響 : ギャップ効果"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:44.370811+00:00"}
