Resumo: | The production of forage grasses is directly related to the morphogenesis.
The knowledge of the morphogenetic and structural variables of forage plants is
important for determining appropriate conditions of grazing livestock to ensure efficient
and sustainable. Thus the objective of this study was to evaluate morphogenetic and
structural responses of three genera of grasses, Brachiaria, Panicum and Cenchrus in a
cutting regime. The experimental design was randomized blocks with three replications
and six treatments. After each section were evaluated for forage production, appearance
and elongation rates of leaves and stem, phyllochron, final leaf length, number of living
leaves, leaf lifespan, leaf senescence rate, tiller density and tiller dynamics. On forage
yield the highest values were obtained in cultivars Xaraes, Piata and Massai. The tiller
density was higher for cv Massai. It is concluded that the cultivars of Panicum and
Brachiaria had a higher tillering dynamics in increasing the turnover rate of tissues that
are indicators of forage production, assuming that the cultivars of these genera are
predisposed to use forage in the Northeast |
