Plant characters concerned with lodging such as internode weight, stem base weight, breaking strength of culm and lodging index were noted at 5 successive 10 days intervals starting on the day of heading. Internode weight, stem base weight and breaking strength increased during the first 10-days period following heading then declined during the next 10- or 20-days period, but reached again the levels at heading or beyond on 40 days following heading. Lodging index increased during the 30-days period following heading, and then declined down. The rice plant was also cut at 5cm above the ground at 5 different growth stages, i.e the day of heading, and 10, 20, 30 and 40 days after heading. Some characters of the ratoon crops were surveyed at the ripening stage. Percentage of ratoon tillers showed the same change as internode weight, stem base weight and breaking strength. Changes of the percentage of ratoon tillers and the ratoon height showed a similar tendency in cuttings during the period from 10 days after heading to 40 days. Traits of the ratoon did not show any clear relationship to breaking strength. However, there were significant and negative correlations between traits of the ratoon and lodging index in cuttings on 20, 30 and 40 days following heading. It was suggested from these correlations that ratoon ability might be used as a test indicator of lodging resistance. The contribution rate of leaf sheath to breaking strength ranged approximately from 15% to 40% in the later period of ripening, and it was depended on cultivars and growth stages.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"生育後期に稲体の地上部を勇除したときの再生能と耐倒伏性たらびにそれに関連する形質との関係を明らかにしようとした。水稲21品種を供試し，節間重，稈基重，挫折重および倒伏指数を出穂日より出穂後40日まで10日おきに計5回調査した。また倒伏に関連する形質を調査したそれらの日に，地際より5cmで地上部を剪除し，剪除後40日に再生茎率および再生草丈を調査した。再生茎率および再生草丈により再生能を評価した。\n節間重，稈基重および挫折重はほぼ同様の推移を示した。それらは出穂後0日より10日にかけて増大し，その後20日または30日まで減少し40日には再び増大した。倒伏指数は出穂後0日から30日まで増大し，その後減少した。再生茎率は節間重，稈基重および挫折度とほぼ同様に推移し，再生草丈の推移も出穂後10日以降剪除では再生茎率の推移とほぼ同様であった。再生能と倒伏指数ならびにそれに関連する形質との相関関係を調べた結果，出穂後20日以降に地上部を剪除したときの再生茎率および再生草丈と出穂後20日以降の倒伏指数との間に有意な負の相関が認められたことから，耐倒伏性の間接的な検定に再生能を利用しうることが示唆された。たお再生能と挫折重との間には有意な相関がほとんど認められたかった。\n再生能と密接に関連する倒伏指数の一構成要素である挫折重に対する葉鞘の寄与率を調べた結果，登熟後期における葉鞘の寄与率は15～40%であったが，品種ならびに生育時期により明らかに異なっていた。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本育種学会","subitem_publisher_language":"ja"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"120004119983","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1270/jsbbs1951.33.251","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00013906","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0536-3683","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_25":{"attribute_name":"KEID","attribute_value_mlt":[{"subitem_text_value":"3354"}]},"item_10001_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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAlternatives":[{"creatorAlternative":"一井, 真比古","creatorAlternativeLang":"ja"}],"creatorNames":[{"creatorName":"一井, 眞比古","creatorNameLang":"ja"},{"creatorName":"イチイ, マサヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Ichii, Masahiko","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"羽田, 勲誠","creatorNameLang":"ja"},{"creatorName":"ハダ, クンセイ","creatorNameLang":"ja-Kana"},{"creatorName":"Hada, Kunsei","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":"2020-11-26"}],"displaytype":"detail","filename":"AN00013906_33_3_251.pdf","filesize":[{"value":"703.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00013906_33_3_251","objectType":"fulltext","url":"https://kagawa-u.repo.nii.ac.jp/record/511/files/AN00013906_33_3_251.pdf"},"version_id":"b3b00c50-6b5f-4b65-8a5a-fb1356f37a2f"}]},"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":"水稲における再生の育種的利用に関する研究 : Ⅱ. 再生能と耐倒伏性との関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水稲における再生の育種的利用に関する研究 : Ⅱ. 再生能と耐倒伏性との関係","subitem_title_language":"ja"},{"subitem_title":"Application of ratoon to a test of agronomic characters in rice breeding II.
