Gas exchange and chlorophyll (Chl) fluorescence were measured on young mature leaves of rose plants (Rosa hybrida cultivars First Red and Twingo) grown in two near-to-tight greenhouses, one under control ambient CO2 concentration, AC (355 micro mol mol-1) and one under CO2 enrichment, EC (700 micro mol mol-1), during four flushes from late June to early November. Supply of water and mineral elements was non-limiting while temperature was allowed to rise freely during daytime.
