Soil salinity is a serious environmental issue in rangeland ecosystems in Iran. Vetiver grass plant species could be a suitable choice for rangeland reclamation due to the salinity tolerance.  The current study aimed to investigate growth, catalase, and phenol compounds of vetiver grass in response to salinity stress. A completely randomized block design with 6 salinity levels (0, 4, 8, 16, 32, 44 ds m^-1) and 3 replications was set up in vitro. The results showed that salinity had no significant effect (p ≥ 0.05) on leaf and root growth characteristics; however, an significant increasing trend was observed on both leaf and root dry weight. The responses of catalase and phenol compounds to salinity were significant in both leaf and root (p ≤ 0.05). Changes of  catalase enzyme in leaves showed a significant increasing trend up to 32 ds m^-1 levels which decreased in 44 ds m^-1. Catalase enzyme activity in root showed an overall decreasing trend compares to control (0 ds m^-1) (p ≤ 0.05). Also, phenol compounds in leaves and root significantly changed due to salinity stress (p ≤ 0.05) with an increasing and decreasing trend, respectively. In overall, this results showed the vetiver grass was well adapted to salinity stress up to 32 ds m^-1 in vitru. Therefore, vetiver grass could be recommended for reclamation projects of saline soils where salinity is up to 32 ds m^-1.
