However, it has been pointed out that the relationship between them is affected by mycorrhizal fungi. Therefore, we estimated the isotope effects related to AM fungi from the difference in nitrogen isotope ratios between maize seedlings grown with and without arbuscular mycorrhizal (AM) fungi, which were infected from the fine roots of Japanese cypress growing in a forest in Shiga Prefecture, Japan. We also applied an isotope mixing model to the nitrogen isotope ratios of leaves, fine roots, and ammmonium and nitrate in the soil water observed in the same forest to estimate the contribution of ammonium and nitrate as nitrogen sources in Japanese cypress trees.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2017年度～2021年度科学研究費補助金(挑戦的研究(萌芽))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"17K19288","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"item_8_text_65","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松尾, 奈緒子","creatorNameLang":"ja"},{"creatorName":"MATSUO, Naoko","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"松田, 陽介","creatorNameLang":"ja"},{"creatorName":"MATSUDA, Yosuke","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-12-22"}],"filename":"2023RP0100.pdf","filesize":[{"value":"127 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://mie-u.repo.nii.ac.jp/record/2000280/files/2023RP0100.pdf"},"version_id":"72731841-a5fc-4254-b565-5879890c61ae"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"窒素安定同位体比","subitem_subject_scheme":"Other"},{"subitem_subject":"アーバスキュラー菌根菌","subitem_subject_scheme":"Other"},{"subitem_subject":"ヒノキ","subitem_subject_scheme":"Other"},{"subitem_subject":"同位体効果","subitem_subject_scheme":"Other"},{"subitem_subject":"アンモニア態窒素","subitem_subject_scheme":"Other"},{"subitem_subject":"硝酸態窒素","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"菌根菌糸－細根間の同位体分別に基づく樹木の窒素吸収における菌根菌依存度の推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"菌根菌糸－細根間の同位体分別に基づく樹木の窒素吸収における菌根菌依存度の推定","subitem_title_language":"ja"},{"subitem_title":"Contribution of arbuscular mycorrhizal fungi to N uptake by Japanese cypress estimated from isotope measurements","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1701929361491"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-12-22"},"publish_date":"2023-12-22","publish_status":"0","recid":"2000280","relation_version_is_last":true,"title":["菌根菌糸－細根間の同位体分別に基づく樹木の窒素吸収における菌根菌依存度の推定"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-09-25T02:43:35.199861+00:00"}
