The effects of various durations of CB treatment on tetraploid induction frequency were examined. Haploid gynogenesis was induced by sperm which were UV-irradiated for 60s at an intensity of 72erg/mm^2/s. CB treatment was effective in inhibiting meiosis, and the optimum time for the suppression of both the 1st and 2nd polar bodies was from 10 to 45min postinsemination, yielding 51.4% gynogenetic tetraploids. The results of this study suggest the possibility of producing gynogenetic tetraploid Pacific oysters.","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_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"685154 bytes","subitem_description_type":"Other"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Faculty of Agriculture, 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":"0040-8719","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":"AA0086391X","subitem_source_identifier_type":"NCID"}]},"item_4_text_72":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Fisheries College, Ocean University of China / Marine Field Station, Field Science Center, Graduate School of Agricultural Science, Tohoku 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":"LI, Qi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KIJIMA, Akihiro"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-22"}],"displaytype":"detail","filename":"KJ00004863361.pdf","filesize":[{"value":"685.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004863361.pdf","url":"https://tohoku.repo.nii.ac.jp/record/65519/files/KJ00004863361.pdf"},"version_id":"aa3b1c0b-390f-404b-bbf8-228ac6bf467d"}]},"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":"Gynogenetic Tetraploid Larvae of the Pacific Oyster Crassostrea gigas Induced by Inhibition of the 1st and 2nd Meiotic Divisions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gynogenetic Tetraploid Larvae of the Pacific Oyster Crassostrea gigas Induced by Inhibition of the 1st and 2nd Meiotic Divisions"}]},"item_type_id":"4","owner":"3","path":["199"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"65519","relation_version_is_last":true,"title":["Gynogenetic Tetraploid Larvae of the Pacific Oyster Crassostrea gigas Induced by Inhibition of the 1st and 2nd Meiotic Divisions"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T11:43:22.245281+00:00"}
