In the frame of OPTIMA project (Optimization of Perennial Grasses for Biomass production, 289642) four perennial grass species (Saccharum spontaneum spp. aegyptiacum, Sorghum halepense, Oryzopsis miliacea and Cimbopogon hirtus) were established at the Experimental Field of Catania University (Catania plain, 10 m a.s.l., 37°27'N, 15°03'E) in spring 2010 in a Mediterranean environment. Gas exchange measurements, using a gas exchange chamber (LICOR 6400 system, LI-COR Bioscience), have been carried out in the dry season between spring...
