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 were performed on leaves of giant reed, using a gas exchange analyzer LICOR 6400. Light response curves of CO2 assimilation were measured on the third leaf from top of the plant.While it is often indicated that giant reed is a C3 crop with very high photosynthetic efficiency, prior to the present study little was known about the photosynthetic response of the species to increasing light intensity. Thus, our findings fill a gap in the current knowledge.
