We measured the gas exchange rate at 350,700,1400 and 2800 ppm of CO_2,25/30℃ of night/day temperature, and 20 to 40 Klx of light intensity. In addition, malate content and PEP carboxylase activity were determined at each CO_2 levels. The gas exchange rate and CO_2 balance of the pineapple in Phase-1 increased with the rise in the CO_2 concentration. Whereas in K. pinnata, K. digremontiana and K. gastonis-bonniere, the gas exchange rate and CO_2 balance were not changed as CO_2 concentration were increased from 350 to 2800 ppm. At the enriched CO_2 conditions, the increase in total CO_2 balance of pineapple was higher than those of K. pinnata, K. digremontiana, and K. gastonis bonnierer. At 2800ppm of CO_2,the increased CO_2 balance relative to those at 350 ppm was 246% for pineapple, 147% for K. pinnata, 158% for K. digremontiana, and 128% for K. gastonis bonnierer. We concluded that the effect of the CO_2 concentration in the pineapple was remarkable.","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/20.500.12000/3660"}]},"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.
