Resumen
El presente estudio evaluó el efecto del nitrógeno y la irradianza sobre la eficiencia fotosintética (Fv/Fm) de Petiveria alliacea. Los resultados mostraron que la fluorescencia disminuyó al aumentar el nivel de irradianza y al disminuir la concentración de nitrógeno. La eficiencia fotosintética fue significativamente mayor en hojas de plantas con mayor disponibilidad de nitrógeno y en ambientes parcialmente sombreados. Las curvas de luz (F-I) en función de la tasa de transporte de electrones (ETR), mostraron que las plantas bajo sombra y expuestas a bajas concentraciones de nitrógeno fueron más susceptibles a bloqueos en su ETR
