Leaf emergence from in vitro cultured bulblets was inhibited after the transplanting into soil without any previous treatment. Temperature treatment (8℃ or less) prior to transplanting had the effect of stimulating leaf emergence from the bulblets. Bulblets, chilled at 4℃ for 12 weeks, accomplished their leaf emergence 20 days after transplanting, but leaf emergence from bulblets chilled for 10 weeks or less depended on the growth temperatures after transplanting, suggesting that chilling at 4℃ for 12 weeks was required to completely break the bulblet dormancy. GA_3 was applied to non-chilled, partly chilled and fully chilled bulblets by immersing and shaking them in distilled water containing GA_3 at a concentration of more than 250mg/l. This treatment stimulated leaf emergence even in non-chilled bulblets after transplanting, but it was less effective for breaking dormancy when compared with the chilling treatment (4℃ for 12 weeks). In partly and fully chilled GA_3-treated bulblets, the GA_3 treatment appeared to have the effect of reducing and substituting for the chilling period in respect to rate and percentage of leaf emergence and in development of bulblets after transplanting.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39164","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Niimi, Yoshiji"}]},{"nameIdentifiers":[{"nameIdentifier":"39165","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Endo, Yukio"}]},{"nameIdentifiers":[{"nameIdentifier":"39166","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Arisaka, Eiichi"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"園芸学会"}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"園芸学会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00025257","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00137626","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"新美, 芳二"}],"nameIdentifiers":[{"nameIdentifier":"39161","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"遠藤, 由紀夫"}],"nameIdentifiers":[{"nameIdentifier":"39162","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"有坂, 英一"}],"nameIdentifiers":[{"nameIdentifier":"39163","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":"2019-07-30"}],"displaytype":"detail","filename":"57(2)_250-257.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"57(2)_250-257.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2805/files/57(2)_250-257.pdf"},"version_id":"afa2c3d8-0233-465a-a6f4-bed261064f18"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ヒメサユリ培養子球の休眠打破に及ぼす低温及びGA_3処理の効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヒメサユリ培養子球の休眠打破に及ぼす低温及びGA_3処理の効果"},{"subitem_title":"ヒメサユリ培養子球の休眠打破に及ぼす低温及びGA_3処理の効果","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","487"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-10-17"},"publish_date":"2008-10-17","publish_status":"0","recid":"2805","relation_version_is_last":true,"title":["ヒメサユリ培養子球の休眠打破に及ぼす低温及びGA_3処理の効果"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:00.330790+00:00"}
