Abstract: The turfgrass plays a crucial role in landscaped ecosystems, including sports fields, golf courses, residential lawns, and parks. However, various turfgrass species face diverse abiotic stresses, including salinity as irrigation with fresh water becomes unavailable. These challenging environmental conditions can result in growth inhibition, damage to cellular structure, and metabolic disturbances. Therefore, the use of salt-tolerant turfgrass species or varieties proves to be one of the most effective methods to mitigate salinity issues. With this aim, a greenhouse experiment was conducted at the experimental station of the Faculty of Sciences in Oujda. The objective was to investigate the impact of saline stress on the morphological and physiological behavior of six grass species widely used in green spaces in Morocco, particularly in the eastern region irrigated with 3 concentrations of saline water. The results revealed that the species A. stolonifera, F. arundinacea, and C. dactylon exhibited some tolerance to salinity, especially at a dose of 3 g/l of NaCl, while the species L. perenne was found to be the most sensitive to saline stress, regardless of the applied dose. Concentrations of 6 g/l and 9 g/l of NaCl led to the decline of all studied species six months after application.
