We listed up the characters relating photosynthesis such as CO_2 compensation point, carboxylation efficiency, maximum photosynthesis at saturation, leaf conductance, and apparent light energy use efficiency. There was statistically significant difference between species or varieties in photosynthesis at atmospheric CO_2 concentration (350ppm). The photosynthesis was regulated mainly with a energy transport system and pi limitation caused by photosynthate storage in cell rather than leaf conductance and carboxylation efficiency. In addition, leaf nitrogen seems to affect the photochemical reaction process, and then finally to CO_2 fixation process.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3679"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
