Plants adapted to defoliation use reserve compounds to regrow leaf area. Modeling grass regrowth should account for these processes. A field experiment was conducted in Gainesville, FL, to study herbage production, partitioning and mobilization of reserve compounds of two tropical grasses (Jiggs bermudagrass and Mulato-2 brachiaria grass), under the combination of two light levels ? 56% and 100% solar radiation, and two N rates ? 30 and 120 kg N ha-1 after each harvest. Herbage mass was quantified at harvest every 28 days.  aCarbon  aForage grasses  aNitrogen metabolism  aCarbono  aForragem  aMetabolismo Nitrogenado  aModelo de Simulação1 aBOOTE, K. J.
