Stress-wave velocity of the trunk in the transverse direction was investigated in 50-year old Larix kaempferi stands in the research forests of Kyushu and Shinshu Universities. The frequency distribution of stress-wave velocity classes of sound trees was normally distributed. However, because the stress-wave velocities of decayed trees were lower than those of sound trees, the stress-wave velocity classes exhibited a J-shaped frequency distribution in stands with decayed trees. The slope of the linear regression between the percentage of the decayed portion along the diameter of the trunk and stress-wave velocity (km・s^<-1>) ranged from -0.011 to -0.015. The y-intercept of the linear regression conformed to the average of the stress-wave velocity of sound trees. These findings provide effective information in diagnosing wood decay using stress-wave velocity measurements.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"樹木医学研究. 12(3):119-124, 2008","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"小林, 元","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.ZNfCgUfp.html"},{"subitem_link_text":"岡野, 哲郎","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.WhDpgUfp.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"樹木医学会"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-0268","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小林,  元"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田代,  直明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山内,  康平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"内海,  泰弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古賀,  信也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大崎,  繁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鍜治,  清弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岡野,  哲郎"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-25"}],"displaytype":"detail","filename":"110007595137.pdf","filesize":[{"value":"667.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110007595137.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/10337/files/110007595137.pdf"},"version_id":"2de9d939-516e-41f8-945b-1d10d6b528c8"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"樹木医学研究カラマツ生立木の非破壊腐朽診断－応力波測定法と打診法の比較－．","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"樹木医学研究カラマツ生立木の非破壊腐朽診断－応力波測定法と打診法の比較－．","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["1017"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-01-05"},"publish_date":"2011-01-05","publish_status":"0","recid":"10337","relation_version_is_last":true,"title":["樹木医学研究カラマツ生立木の非破壊腐朽診断－応力波測定法と打診法の比較－．"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:13:16.588138+00:00"}
