Description:	It was evaluated growth and photosynthetic peformance of two leguminosae woody species under contrasting irradiances environments, Anadenanthera falcata (Benth.) Speg. and Stryphnodendron adstringens (Mart.) Coville. Under total irradiance in open area both species presented greater biomass accumulation, height, stem diameter, total leaf area and higher photosynthetic capacity on area bases (Amaxa). Shaded individuals under canopy modified the biomass partition, presenting greater mean values of leaf area rate (LAR), and smaller values of the specific leaf mass (SLM), repiration in dark (Rd), and apparent photorespiration (Pr) , apparent carboxylation efficiency (eletron transport rate (J). High transitory concentrations of CO2 increased the photosynthetic capacity under total irradiance (83%) and under canopy (71%).
