However, the resultant effects on growth, yield and quality of field-grown rice remain unclear, especially under differing nitrogen (N) availability and/or using cultivars with large panicles. To investigate these, a Free-Air CO_2 Enrichment (FACE) experiment was performed at Wuxi, Jiangsu, China, in 2001-03. A japonica cultivar with large panicle was exposed to two [CO_2] (ambient, ambient+200μmol mol^<-1>) at three levels of N supply (15, 25, 35gNm^<-2>). FACE accelerates phenology significantly, with 3-5 days earlier in heading and 6-9 days earlier in maturity across 3 years. FACE significantly increased the grain yield by 12.8%, which was mainly due to substantially increased panicle number per square meter (+19%) as result of significant increases in tillering occurrence speed. However the spikelet number per panicle was greatly reduced (-8%), which was due mainly to the significant increase in degenerated spikelets per panicle (+52%) while differentiated spikelets per panicle showed no change. Overall DM accumulation at harvest was stimulated somewhat more (+16%) by FACE, compared to grain yield, by an average of 13% by FACE, thus resulting in 3% reduction in harvest index. FACE caused significant reduction in shoot N concentration (-7%) and significant increase in P concentration (+14%) at grain maturity, resulting in significant increase in N use efficiency and significant reduction in P use efficiency. Both shoot N uptake (+9%) and P uptake (+33%) showed significant increase at harvest, which was mainly due to significant enhanced N and P uptake during early growth stage. On a per plant basis, FACE significantly increased cumulative root volume, root dry weight, adventitious root length and adventitious root number at heading, which was mainly associated with significant increases in root growth rate during early growth period, while total surface area, active adsorption area and root oxidation activity per unit root dry weight showed significant reduction. As for grain quality, FACE cause deterioration of processing suitability and appearance quality drastically, the nutritive value of grain was also negatively influenced by FACE due to a reduction in grain protein and Cu concentration. By contrast, FACE resulted in better eating/cooking quality. For most cases, no [CO_2]×N interaction was detected for the growth, yield and quality parameters. Data from this study has important implications for fertilizer (e.g. N, P) management and variety selection in rice production systems under future elevated [CO_2] conditions.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類","subitem_description_type":"Other"}]},"item_4_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Special Review","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"1790238 bytes","subitem_description_type":"Other"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Field Science Center, Graduate School of Agricultural Science, Tohoku University"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2433-6122","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12005506","subitem_source_identifier_type":"NCID"}]},"item_4_text_72":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Key Lab of Crop Genetics & Physiology of Jiangsu Province, Yangzhou University / Key Lab of Crop Genetics & Physiology of Jiangsu Province, Yangzhou University / Key Lab of Crop Genetics & Physiology of Jiangsu Province, Yangzhou University / Key Lab of Crop Genetics & Physiology of Jiangsu Province, Yangzhou University"}]},"item_4_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":"WANG, Yulong"}],"nameIdentifiers":[{"nameIdentifier":"152328","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YANG, Lianxin"}],"nameIdentifiers":[{"nameIdentifier":"152329","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HUANG, Jianye"}],"nameIdentifiers":[{"nameIdentifier":"152330","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"DONG, Guichun"}],"nameIdentifiers":[{"nameIdentifier":"152331","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":"2017-02-22"}],"displaytype":"detail","filename":"KJ00004863521.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004863521.pdf","url":"https://tohoku.repo.nii.ac.jp/record/64135/files/KJ00004863521.pdf"},"version_id":"e3a35c62-59ca-4d2f-a707-3f34718e6138"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Free-Air CO_2 Enrichment (FACE)","subitem_subject_scheme":"Other"},{"subitem_subject":"Growth","subitem_subject_scheme":"Other"},{"subitem_subject":"Quality","subitem_subject_scheme":"Other"},{"subitem_subject":"Rice","subitem_subject_scheme":"Other"},{"subitem_subject":"Yield","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"The impact of free-air CO_2 enrichment (FACE) and N supply on growth, yield and quality of rice crops with large panicle","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The impact of free-air CO_2 enrichment (FACE) and N supply on growth, yield and quality of rice crops with large panicle"}]},"item_type_id":"4","owner":"3","path":["198"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"64135","relation_version_is_last":true,"title":["The impact of free-air CO_2 enrichment (FACE) and N supply on growth, yield and quality of rice crops with large panicle"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T23:43:14.719364+00:00"}
