Fresh seeds, one week after harvest, did not germinate at temperatures above 10℃. Seeds after-ripened for more than 4 months germinated optimally at 15℃ or therabouts. However, even the seeds after-ripened for 28 months or more never geminated at 30℃. Exposure to 5℃ followed by 30℃ resulted in germination at 30℃ in regardless of the after-ripened period. Exposure to 15℃, referred to as chilling, followed by 30℃, or the reverse to 7-8 month-seeds resulted in qualitative and quantitative inhibition at 30℃, whereas exposing 31-32 month-seeds to alternating temperatures resulted in promotion of germination at 30℃. Diurnal thermoperiodic exposure of the seeds after-ripened for 8 months, chilling and 30℃, resulted in germination within a narrow time range of chilling from 16 h to 24 h, irrespective of the number of cycles.  However, diurnal exposure to the seeds after-ripened for 32 months resulted in germination at a wider time range of chilling from 2 h to 24 h depending upon the number of cycles. The roles of low temperatures and high temperatures, and of their interaction on the germination of A.fatua seeds with particular regard to the after-ripened period are discussed.","subitem_description_type":"Abstract"},{"subitem_description":"5℃から30℃の各種の一定温度，及び5℃後の30℃，15℃後の30℃或いは30℃後の15℃の温度変化に対する野生エンバク（Avena fatua)の種子（えい果）の発芽反応を，収穫後の期間（後熟期間）が異なるる種子を用いて調べた。収穫後1週間の種子は，10℃より高い温度で発芽しなかった。4か月以上経過した種子は15℃，或いはその近くの温度で最も強く発芽した。しかし24か月以上の種子でも30℃では発芽しなかった，即ち2次休眠に入った。いずれの後熟期間の種子でも，5℃の後30℃に置くと短期間で発芽した。この結果は，発芽の初期過程は低温によって誘導され，その後の過程は高温によって促進されることを示唆している。15℃後の30℃，或いはその逆の温度変化に対して，7－8か月の種子の発芽は，30℃によって質的並びに量的に抑制された。しかし，後熟期間が経過するにつれて，30℃の抑制は減少し，31-32か月の種子の発芽は，30℃によってむしろ促進された。また，15℃と30℃の日周的温周期こ対して，8か月の種子は，15℃が16時間から24時問の狭い時間範囲でのみ発芽し，それ以下の時間では，この温周期の回数を増加しても発芽しなかった。これに対して，32か月種子の発芽の時間範囲は温周期の回数の増加にともない広くなり，6回の温周期で，2時間から24時間の範囲で発芽した。この実験結果は，短い後熟期間の種子の発芽過程では，15℃と30℃は相互に拮抗的に作用するが，長い後熟期間の種子の発芽過程では，この両者の温度は相助的に作用することを示唆している。","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学生物資源学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-0471","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10073846","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"616","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"野生エンバクの種子発芽に及ぼす温度と後熟期間の作用"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"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":"Ogawa, Yukiyoshi","creatorNameLang":"en"},{"creatorName":"小川, 幸持","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"AN100738460000808.pdf","filesize":[{"value":"382.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN100738460000808.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5746/files/AN100738460000808.pdf"},"version_id":"e7c258cb-d0ee-498f-a33d-d3d823bfa4be"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"After ripened","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"period Avena","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fatua Dormancy seed","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"germination Temperature","subitem_subject_language":"en","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":"Thermo-control of Germination of Avena fatua Seeds in Relation to After-ripened Period","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Thermo-control of Germination of Avena fatua Seeds in Relation to After-ripened Period","subitem_title_language":"en"}]},"item_type_id":"4","owner":"13","path":["451"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-11"},"publish_date":"2007-06-11","publish_status":"0","recid":"5746","relation_version_is_last":true,"title":["Thermo-control of Germination of Avena fatua Seeds in Relation to After-ripened Period"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-12T02:44:01.503145+00:00"}
