Description
Results of two grazing experiments on the effect of maintaining contrasting sward states upon leaf appearance rate of individual tillers (LAR) and tiller density (D) are reported. The following species were evaluated: Cynodon dactylon(Cd), Leersia hexandra(Lh), y Paspalum dilatatum(Pd) in a natural grassland of the Flooding Pampa, and Festuca arundinacea in a sown pasture. Except for Pd, LAR decreased with the increment of sward surface height. The degree of this morphogenetic plasticity varied among species. Implications for the stability of grass populations under continuous grazing are suggested; the effect of sward state upon LAR may represent one alternative way of affecting D through the defoliation management.
