Conteúdo: | Photosynthetic capacity on area (P Nmaxa) and mass bases (P Nmaxm) and specific leaf mass (SLM) were determined in twenty woody species of Cerrado under field conditions. The mean values obtained for P Nmaxa [11.4 umol(CO2) m-2s -1], P Nmaxm [78 umol(C)2) kg-1 s-1] and SLM (150 g m-2) were compared with mean values found for decidous and evergreen sclerophyllous species growing also under field conditions. P Nmaxm and SLM were statistically different among decidous, Cerrado and evergreen sclerophyllous species. There was a gradual decrease of P Nmaxm and an increase of SLM from deciduous to evergreen sclerophyllous species. Woody species of Cerrado showed mean values of P Nmaxm and SLM between decidous and evergreen species indicating its brevideciduousness. The comparison using mean values of P Nmaxm and SLM belonging to deciduous, Cerrado and evergreen sclerophyllous species was suitable to confirm the interdependence among life span, structure and physiological attributes of leaf.
