Pyramidalis×P. tomentosa and P. euphratica) collected from the semi-arid region of China, the change in the photosynthetic rate of seedlings during dehydration of soil was examined. Photosynthetic rate and stomatal conductance decreased as the water content in the soil decreased. The change in the photosynthetic rate during dehydration of the soil did not differ among chinese poplars and the improved poplar FS-51 (P. maximowiczii×P. plantierensis). From the analysis of the relationship between intercellular CO2 concentration and photosynthetic rate, it was found that the photosynthetic mechanism of P. alba cv. Pyramidalis×P. tomentosa or P. euphratica is more tolerant to water stress than that of FS-51.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54726","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KANG, Jae-Myung"}]},{"nameIdentifiers":[{"nameIdentifier":"54727","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TANGE, Takeshi"}]},{"nameIdentifiers":[{"nameIdentifier":"54728","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOJIMA, Katsumi"}]},{"nameIdentifiers":[{"nameIdentifier":"54729","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IDE, Yuji"}]},{"nameIdentifiers":[{"nameIdentifier":"54730","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SASAKI, Satohiko"}]}]},"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":"東京大学農学部附属演習林研究部"},{"subitem_text_value":"Department of Forest Science, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"Research Division of the University Forests, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"康, 才明"}],"nameIdentifiers":[{"nameIdentifier":"54721","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"丹下, 健"}],"nameIdentifiers":[{"nameIdentifier":"54722","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小島, 克己"}],"nameIdentifiers":[{"nameIdentifier":"54723","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"井出, 雄二"}],"nameIdentifiers":[{"nameIdentifier":"54724","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐々木, 恵彦"}],"nameIdentifiers":[{"nameIdentifier":"54725","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":"esrh094006.pdf","filesize":[{"value":"509.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh094006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25439/files/esrh094006.pdf"},"version_id":"72c5e3c9-3272-4dec-9fd0-54d79613b41f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"中国産ポプラ","subitem_subject_scheme":"Other"},{"subitem_subject":"組織培養苗","subitem_subject_scheme":"Other"},{"subitem_subject":"耐乾燥性","subitem_subject_scheme":"Other"},{"subitem_subject":"光合成","subitem_subject_scheme":"Other"},{"subitem_subject":"気孔コンダクタンス","subitem_subject_scheme":"Other"},{"subitem_subject":"Chinese poplar","subitem_subject_scheme":"Other"},{"subitem_subject":"Drought tolerance","subitem_subject_scheme":"Other"},{"subitem_subject":"Photosynthetic activity","subitem_subject_scheme":"Other"},{"subitem_subject":"Stomatal conductance","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":"土壌の乾燥にともなう中国産ポプラ3種の光合成速度の変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"土壌の乾燥にともなう中国産ポプラ3種の光合成速度の変化"}]},"item_type_id":"4","owner":"1","path":["2554","2553"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25439","relation_version_is_last":true,"title":["土壌の乾燥にともなう中国産ポプラ3種の光合成速度の変化"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:41.577053+00:00"}
