Inc.) with time. Moreover, we calculated the elasticity indexes from resonant frequencies and fruit weights and, showed the timecourse change in the elasticity index of fruits during storage. The second resonant frequency of 'Kosui' fruits at harvest was 680 Hz and the third resonant frequencies of 'Niitaka' and 'Shinko' fruits at harvest were 852 Hz and 841 Hz, respectively. Moreover, the elasticity index calculated from the second resonant frequency of 'Kosui' fruit at harvest was approximately 22 and the elasticity indexes calculated from the third resonant frequencies of 'Niitaka' and 'Shinko' fruit at harvest were approximately 56 and 49, respectively. From the results that the elasticity indexes of these three cultivars decreased during storage, the possibility was suggested that the elasticity index could be used as a new maturity indicator of Japanese pear fruits. Modified atmosphere packaging of fruits helped the development of skin blackening ('Niitaka'), diseases attributed to storage ('Shinko'), and core breakdown ('Kosui' and 'Shinko'). However, the water loss from fruits was prohibited by modified atmosphere packaging, and the decrease of elasticity index was also prohibited. From these results, it was suggested that decrease of the elasticity index in Japanese pear fruit is related to the water loss.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"163164","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kurosaka, Shun"}]},{"nameIdentifiers":[{"nameIdentifier":"163165","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Chino, Shuji"}]},{"nameIdentifiers":[{"nameIdentifier":"163166","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ohta, Yuuki"}]},{"nameIdentifiers":[{"nameIdentifier":"163167","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saito, Yotaro"}]},{"nameIdentifiers":[{"nameIdentifier":"163168","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakai, Yu"}]},{"nameIdentifiers":[{"nameIdentifier":"68","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kojima, Kiyohide"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学農学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183393","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03858634","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"黒坂, 俊"}],"nameIdentifiers":[{"nameIdentifier":"163158","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"知野, 秀次"}],"nameIdentifiers":[{"nameIdentifier":"163159","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"太田, 祐樹"}],"nameIdentifiers":[{"nameIdentifier":"163160","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"齋藤, 洋太郎"}],"nameIdentifiers":[{"nameIdentifier":"163161","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂井, 優"}],"nameIdentifiers":[{"nameIdentifier":"163162","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"児島, 清秀"}],"nameIdentifiers":[{"nameIdentifier":"68","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":"2019-08-20"}],"displaytype":"detail","filename":"62(2)_81-87.pdf","filesize":[{"value":"847.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62(2)_81-87.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28367/files/62(2)_81-87.pdf"},"version_id":"d3bfaec9-bdd0-45fe-ba67-25c31a21b2e3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"非破壊計測","subitem_subject_scheme":"Other"},{"subitem_subject":"共鳴周波数","subitem_subject_scheme":"Other"},{"subitem_subject":"MA包装","subitem_subject_scheme":"Other"},{"subitem_subject":"水分消失","subitem_subject_scheme":"Other"},{"subitem_subject":"低温","subitem_subject_scheme":"Other"},{"subitem_subject":"Low temperature","subitem_subject_scheme":"Other"},{"subitem_subject":"Modified atmosphere packaging","subitem_subject_scheme":"Other"},{"subitem_subject":"Nondestructive measurement","subitem_subject_scheme":"Other"},{"subitem_subject":"Resonant frequency","subitem_subject_scheme":"Other"},{"subitem_subject":"Water loss","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":"ニホンナシ‘幸水’、‘新高’および‘新興’におけるMA包装が果実貯蔵に及ぼす影響および貯蔵期間中の弾性指標のモニタリング","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ニホンナシ‘幸水’、‘新高’および‘新興’におけるMA包装が果実貯蔵に及ぼす影響および貯蔵期間中の弾性指標のモニタリング"},{"subitem_title":"ニホンナシ‘幸水’、‘新高’および‘新興’におけるMA包装が果実貯蔵に及ぼす影響および貯蔵期間中の弾性指標のモニタリング","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1597"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-14"},"publish_date":"2010-07-14","publish_status":"0","recid":"28367","relation_version_is_last":true,"title":["ニホンナシ‘幸水’、‘新高’および‘新興’におけるMA包装が果実貯蔵に及ぼす影響および貯蔵期間中の弾性指標のモニタリング"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:13.604792+00:00"}
