The animals having black gills increased gradually in number about 10 days onward after nuclear insertion. \n3) Based on the above results the following conclusion may be possible that the color change occuring in gills seems to be attributable to certain enviromental factors and physiological conditions. \n4) In the black gill, there are found many dark violet granules in the epithelial cells forming the gill filaments and some other components. The granules can be extracted from the fresh gill tissue through the use of acid solvent such as HCl-alcohol. The extract shows red fluorescence under the exposure to ultra-violet. \n5) There are detected pigments of similar nature in the posterior part of adductor, foot, outer lamella of pallial margin and auricle of the pearl-oyster. \n6) The chemical composition and physiological role of the pigments have remained unknown, being a subject of future investigation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立真珠研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Pearl Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"pearl_k_418","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本真珠振興会Archive"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://jp-pearl.com/wp-content/uploads/2018/04/houkoku005.pdf#007","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00091717","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Uemoto, Haruhiko","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"植本, 東彦","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ウエモト, ハルヒコ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Uemoto","familyNameLang":"en"},{"familyName":"植本","familyNameLang":"ja"},{"familyName":"ウエモト","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Haruhiko","givenNameLang":"en"},{"givenName":"東彦","givenNameLang":"ja"},{"givenName":"ハルヒコ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3292","nameIdentifierScheme":"WEKO"}]}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"アコヤガイ Pinctada martensii (Dunker) の鰓の色調について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アコヤガイ Pinctada martensii (Dunker) の鰓の色調について","subitem_title_language":"ja"},{"subitem_title":"studies on the color tone in the gill of the pearl oyster, Pinctada martensii","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-27"},"publish_date":"2024-06-27","publish_status":"0","recid":"2008962","relation_version_is_last":true,"title":["アコヤガイ Pinctada martensii (Dunker) の鰓の色調について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T02:40:39.538221+00:00"}
