At the high altitude, the atmospheric pressure and partial pressure of CO_2 at intercellular air spaces in the leaf (C_<i360>) decreased to 77% and 78% of those at the low altitude, respectively. On the other hand, the efficiency of photosynthetic CO_2-utilization was apparently higher at the high altitude because of a mitigation of the O_2-inhibition of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) under low ambient partial pressure of O_2. This stimulation of photosynthesis partly compensated a photosynthetic depression due to the low C_<i360>, and the net assimilation rate (A_<n360>) at the high altitude retained 94% of the value at the low altitude. A theoretical model indicated that the stimulation of photosynthesis at high altitudes depend on internal conductance (g_i) and/or on Rubisco content. The model demonstrated that low atmospheric pressure at high altitudes caused severe restrictions of photosynthesis when leaves had a small g_i and/or a large amount of Rubisco, whichever are repeatedly reported in alpine plants.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"ブナの葉の光合成を標高0ｍと2360ｍの2地点で測定比較した結果、CO2分圧の低下は光合成の低下をもたらすが、O2分圧の低下は酸素によるRubisco活性の抑制を緩和する方向に働くことを示しています。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110006385874","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2007.02.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2007.02.001","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"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":"Sakata, Tsuyoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kachi, Naoki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yokoi, Yota"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakata, Tsuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kachi, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yokoi, Yota","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ribulose-1,5-bisphosphate carboxylase","subitem_subject_scheme":"Other"},{"subitem_subject":"oxygenase (Rubisco)","subitem_subject_scheme":"Other"},{"subitem_subject":"Internal diffusion conductance (g_i)","subitem_subject_scheme":"Other"},{"subitem_subject":"Atmospheric pressure","subitem_subject_scheme":"Other"},{"subitem_subject":"Photosynthetic CO_2 use efficiency","subitem_subject_scheme":"Other"},{"subitem_subject":"A-C_i curves","subitem_subject_scheme":"Other"},{"subitem_subject":"Ribulose-1,5-bisphosphate carboxylase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"oxygenase (Rubisco)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Internal diffusion conductance (g_i)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Atmospheric pressure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Photosynthetic CO_2 use efficiency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"A-C_i curves","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Quantitative evaluation of the counterbalance between photosynthetic stimulation and depression caused by low partial pressure of O_2 and CO_ 2 in alpine atmospheres","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Quantitative evaluation of the counterbalance between photosynthetic stimulation and depression caused by low partial pressure of O_2 and CO_ 2 in alpine atmospheres"},{"subitem_title":"Quantitative evaluation of the counterbalance between photosynthetic stimulation and depression caused by low partial pressure of O_2 and CO_ 2 in alpine atmospheres","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1366"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-15"},"publish_date":"2014-10-15","publish_status":"0","recid":"10065","relation_version_is_last":true,"title":["Quantitative evaluation of the counterbalance between photosynthetic stimulation and depression caused by low partial pressure of O_2 and CO_ 2 in alpine atmospheres"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:21:38.376911+00:00"}
