NiF8 and S. officinarum cv. Badila), C_4 plants have been well-known a having strong resistance to VPD as compared with C_3 plants. In addition, we determined the carboxylation efficiency, obtained from the initial slope of the A/Ci curve, and apparent quantum yield, acquired from the initial slope of photosynthetic light response curve at different VPD conditions. The results indicated that there were no changes in photosynthesis and leaf water potential in sugarcane used with increasing VPDs. Transpiration rate was increased linearly with increasing VPD. Leaf conductance and internal CO_2 concentration were decreased with increasing VPD. The carboxylation efficiency and apparent quantum yield were decreased at high VPD, suggesting that photosynthetic activities were damaged at the high evaporation demands. However, there was no statistic significance between VPD treatments. Leaf water potential, osmotic potential and pressure potential were not altered at different VPD. It was suggested that the decreases in leaf conductance at high VPD were attributed to the direct responses of stomata to VPD.", "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/20.500.12000/3678"}]}, "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.
