ABSTRACT
The morphogenetic characteristics of eight native grasses of South Brazil were evaluated during autumn. They were classifi ed in a functional typology, according to dry matter content and specifi c leaf area (A, B, C, D): Axonopus affi nis (A), Andropogon lateralis (B), Paspalum notatum (B), Paspalum plicatulum (C), Piptochaetium montevidense (C) Aristida laevis (D), Saccharum angustifolius (D) and Sorghastrum pellitum (D), under two nitrogen (N) fertilization levels (zero and 200kg ha -1 N). Experimental design was completely randomized in a factorial arrangement: eight (species) x two (N levels) with three replicates or four (functional types) x two (N levels
