The maximum photosynthetic rate of 1.23mgO_2/mg chl. α/h was obtained under the light intensity of 25μE/m^2/s. In a higher light condition above 80μE/m^2/s, a depression of the rate caused by photo-inhibition was observed. These results demonstrated the low-light-adaptation of Antarctic ice-algae under the exceedingly low light conditions. The light condition under the ice was largely controlled by the thickness of snow covering the fast ice as well as by the variation of solar radiation. The optimum temperature for photosynthesis of the ice-algae was about 8℃, while the rates of photosynthesis reduced at higher temperatures. In the present area, an average specific growth rate (μ) of the ice-algae was 0.25 div./day.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Fisheries"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1986-12-01"}],"displaytype":"detail","filename":"KJ00000012583.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012583","url":"https://nipr.repo.nii.ac.jp/record/2030/files/KJ00000012583.pdf"},"version_id":"a60c1a05-b4eb-43f3-bfa4-2ee41bece765"}]},"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":"Photosynthetic nature of ice-algae under fast ice near Syowa Station, Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Photosynthetic nature of ice-algae under fast ice near Syowa Station, Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["398"],"pubdate":{"attribute_name":"公開日","attribute_value":"1986-12-01"},"publish_date":"1986-12-01","publish_status":"0","recid":"2030","relation_version_is_last":true,"title":["Photosynthetic nature of ice-algae under fast ice near Syowa Station, Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:46:08.350285+00:00"}
