The study was conducted in Nagasaki, in the Kyushu region of Japan, where heat stress on rice has become increasingly evident. Although elevated CO2 significantly improved the net hotosynthesis and whole-plant growth of the cultivars, there were no significant effects on grain yield, which in turn reduced harvest index. In both cultivars, adverse effects occurred with elevated CO2, such as reductions in spikelet fertility and grain appearance quality, which are typical manifestations of heat stress in rice. During the flowering period, the air temperature was high that spikelet fertility was reduced even under ambient CO2 conditions for both cultivars. These results suggest that, under high-temperature conditions, elevated CO2 could induce or exacerbate the manifestations of heat stress in rice. Because transpiration rate in the flag leaf was significantly reduced by the exposure to elevated CO2, it is possible that elevated CO2 increased plant temperature via a reduction in transpiration during flowering period, although we did not detect significance of the increase in leaf and panicle temperature. To ensure a more confident conclusion, further studies focusing on the effects of elevated CO2 on the determinants of spikelet fertility and grain appearance quality with other cultivars in different year are required.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Asian Journal of Atmospheric Environment, 16(3), art. no. 2022044; 2022　","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Asian Association for Atmospheric Environment"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.5572/ajae.2022.044","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2022 by Asian Association for Atmospheric Environment This is an open-access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0/), which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited."}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1976-6912","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","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":"Yamaguchi, Masahiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kamiya, Shoma"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kokubun, Dai"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakayama, Tomoki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yonekura, Tetsushi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kohno, Yoshihisa"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-11-08"}],"displaytype":"detail","filename":"AJAE16_2022044.pdf","filesize":[{"value":"622.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AJAE16_2022044.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/27731/files/AJAE16_2022044.pdf"},"version_id":"b36a8f46-ea3e-4d9f-afb4-780dfdf4c4c9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Heat stress","subitem_subject_scheme":"Other"},{"subitem_subject":"Japonica rice","subitem_subject_scheme":"Other"},{"subitem_subject":"Open-top chamber","subitem_subject_scheme":"Other"},{"subitem_subject":"Stomatal conductance","subitem_subject_scheme":"Other"},{"subitem_subject":"Transpiration rate","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Elevated CO2 Could Reduce Spikelet Fertility and Grain Appearance Quality of Rice (Oryza sativa L.)
