The scope of this study was to assess the adequacy of four models (Blackman response, negative exponential, rectangular hyperbola and non-rectangular hyperbola) for describing the CO2 assimilation irradianceĀ¬response curve in leaves of giant reed, a promising energy crop with remarkable biomass productivity in Mediterranean areas. A field study was conducted in Anzola dell'Emilia (Bologna), Northern Italy, during the year 2011, on a crop stand of giant reed established in 2007. Periodical measures of CO2 assimilation...
