Almost all samples of these two species showed to have n=20. This may be the diploid level derived from x=10. In the present study, however, the triploid level (n=30) was confirmed in one sample of B. pseudotriquetrum, and the morphological features of chromosomes, leaves and cells are compared with those of n=20. Such polyploidy was hitherto unknown in this species. It is possible to say that the polyploidy increases in incidence with latitude in the polar areas.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008658","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"59(21)","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Department of Biology, College of General Education, Osaka University"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"大阪大学教養部生物学教室"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1990-03-01"}],"displaytype":"detail","filename":"KJ00000139923.pdf","filesize":[{"value":"244.9 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139923","url":"https://nipr.repo.nii.ac.jp/record/8658/files/KJ00000139923.pdf"},"version_id":"d7eca9b0-bdc0-48c1-81d2-23ab6451608d"}]},"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":"南極昭和基地周辺から採集されたBryum属の倍数性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南極昭和基地周辺から採集されたBryum属の倍数性"},{"subitem_title":"Polyploidy in Bryum collected from the Syowa Station area, Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1095"],"pubdate":{"attribute_name":"公開日","attribute_value":"1990-03-01"},"publish_date":"1990-03-01","publish_status":"0","recid":"8658","relation_version_is_last":true,"title":["南極昭和基地周辺から採集されたBryum属の倍数性"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:06:35.191542+00:00"}
