Rock oyster, Grassostrea echinata, and three species of pearl oyster, Pinctada fucata, P.\nmaxima and Pteria penguin, were used as materials.\n2. The discharged eggs of C. echinat and P. fucata are at the first maturation prophase.\nThe eggs of these species obtained from the excised gonads, though they are underripe\nwhen stocked in the ovaries, can be rendered fertilizable before the nucleus shows any\nsigns of breaking down.\n3. The oyster eggs are progressively improved in fertilizability while kept standing\nin sea water. A similar situation has been obtained in P. fucata eggs if they are exposed to\nammoniacal sea water. The pearl oyster eggs which have undergone the nuclear breakdown in plain sea water are not always fertilizable.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"4. The eggs of Pinctada maxima and Pteria penguin which are obtainable from the excised gonads become mature if they are kept standing in ammoniacal sea water but not in\nplain sea water. The eggs of these forms are not rendered fertilizable until the beginning\nof the nuclear breakdown.\n5. Relationships between the cortex maturation and the nuclear breakdown have\nbeen discussed. It has been postulated that these two phenomena, though very probably\nthey are started by some identical reaction(s), are not linked with a strict cause-and-effect\nrelation, but that each is accomplished through a divergent way in the later part. This\nview seems to be able to explain the known facts on a much simpler assumption as compared with the classic notion which implies the cortex maturation is induced by some substances liberated from the nucleus.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"660","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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":"WADA, Seiji K.","creatorNameLang":"en"},{"creatorName":"和田, 清治","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"104001","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":"2016-10-28"}],"displaytype":"detail","filename":"AN00040498_v10_p1-8.pdf","filesize":[{"value":"4.7 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040498_v10_p1-8.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/8053/files/AN00040498_v10_p1-8.pdf"},"version_id":"3bbc3b39-d7de-4529-baa2-b073cee764a2"}]},"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":"Fertilizability of Crassostrea and Pinctada Eggs as Related to Germinal Vesicle Breakdown","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fertilizability of Crassostrea and Pinctada Eggs as Related to Germinal Vesicle Breakdown","subitem_title_language":"en"},{"subitem_title":"カキおよびシンジュガイ卵の受精と卵核胞の崩壊","subitem_title_language":"ja"}]},"item_type_id":"7","owner":"18","path":["40","4847"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-06-14"},"publish_date":"2012-06-14","publish_status":"0","recid":"8053","relation_version_is_last":true,"title":["Fertilizability of Crassostrea and Pinctada Eggs as Related to Germinal Vesicle Breakdown"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-30T01:10:30.274336+00:00"}
