crops (Arundo donax L. and Panicum virgatum L.) grown under water stress in greenhouse
conditions. Plants were exposed to three water stress levels: control (C, 100% Pot Capacity),
mild stress (MS, 50% PC) and severe stress (SS, 25% PC). Photosynthesis, fluorescence
parameters and relative water content were measured at the beginning (Ti) and the end of
the experiment (Tf). Biomass parameters were measured at Tf. Short-term double labelling …
