The response of some photosynthetic parameters (CO2 assimilation, transpiration rate, stomatal conductance, intercellular CO2 concentration, water-use efficiency, and chlorophyll content), shoot development, the morphological features root system to differentiated conditions nitrogen supply was tested in festulolium (Festulolium braunii K. Richert A. Camus) varieties (Felopa Sulino). Nitrogen fertilization with no added [0 g(N)], single dosage [0.23 double [0.46 g(N)] per pot year applied. Lack resulted formation longer finer roots lowered content, resulting lower dry matter accumulation. Application both dosages improved aboveground features, while were enhanced without fertilization. Dependence between physiological traits significant positively correlated case parts plants negatively belowground parts.
