Plants were grown by the deep-flow technique for 64 days after transplanting, using nutrient solutions with different P levels (0.2, 0.4, 0.8, 1.4, or 2.2 meq L^–1). The P concentration in the nutrient solution was strongly and significantly correlated with P absorption (r = 0.982) and total dry matter (r = 0.915). There was a linear correlation between the P level in the nutrient solution and P absorption. However, the increase in total dry matter in response to the P level in the nutrient solution exhibited a peak, with no additional increase of total dry matter at a P concentration of 1.4 meq L^–1 or more. For plants grown with a low P level ( ≤ 0.8 meq L^–1), dry matter production was significantly reduced compared with growth in other treatments because of decreased leaf area development and decreased nutrient uptake. There was a strong and significant correlation (r = 0.946) between the P concentrations in the leaf petiole sap (PPS) and in the leaves (PL) : PL = 3.134 × ln(PPS) - 6.267 PPS increased linearly with increasing P level in the nutrient solution. These results suggest that to sustain dry matter production, the P concentrations in the nutrient solution and the leaf petiole sap should be maintained at ≥ 0.8 meq L–1 and ≥ 90μL L^–1, respectively. However, at a P concentration in the nutrient solution higher than 1.4 meq L^–1, the P fertilization efficiency decreases.\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001788","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業・食品産業技術総合研究機構"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00001788","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-6984","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Ahn, Dong-Hyuk","creatorNameLang":"en"},{"creatorName":"安, 東赫","creatorNameLang":"ja"},{"creatorName":"アン, ドンヒョク","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"岩崎, 泰永"},{"creatorName":"イワサキ, ヤスナガ","creatorNameLang":"ja-Kana"},{"creatorName":"IWASAKI, Yasunaga","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"河崎, 靖"},{"creatorName":"カワサキ, ヤスシ","creatorNameLang":"ja-Kana"},{"creatorName":"KAWASAKI, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"東出, 忠桐"},{"creatorName":"ヒガシデ, タダヒサ","creatorNameLang":"ja-Kana"},{"creatorName":"HIGASHIDE, Tadahisa","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"中野, 明正"},{"creatorName":"ナカノ, アキマサ","creatorNameLang":"ja-Kana"},{"creatorName":"NAKANO, Akimasa","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"鈴木, 克己"},{"creatorName":"スズキ, カツミ","creatorNameLang":"ja-Kana"},{"creatorName":"SUZUKI, Katsumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-19"}],"displaytype":"detail","filename":"nivts_report_No13p19-26p.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nivts_report_No13p19-26p.pdf","url":"https://repository.naro.go.jp/record/1840/files/nivts_report_No13p19-26p.pdf"},"version_id":"0df9d300-d504-492f-b2c2-f65ec9aeefbd"}]},"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":"培養液のリン濃度がキュウリの生育およびリン吸収に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"培養液のリン濃度がキュウリの生育およびリン吸収に及ぼす影響"},{"subitem_title":"Influence of Phosphorus Concentration in the Nutrient Solution on the Growth and Phosphorus Absorption of Hydroponic Cucumber","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["324"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"1840","relation_version_is_last":true,"title":["培養液のリン濃度がキュウリの生育およびリン吸収に及ぼす影響"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-07-20T02:22:32.544737+00:00"}
