| Özet |
| Salinity stress causes an increasingly pervasive threat to agricultural productivity, including turf and forage grasses. This study aimed to reveal how salinity stress affects the physiological and biochemical levels of Festuca arundinacea (tall fescue) cultivars differing in salinity tolerance. The salinity stress treatments were assessed through the evaluation of growth measures, biochemical profiles, and the activity of antioxidative enzymes in four tall fescue cultivars having different salinity stress tolerance (tolerant, moderate-high, moderate-low, and sensitive). The results revealed that the tolerant cultivar named ‘Titan RX’(tolerant cv.) showed increased root growth and maintained physiological status under salinity stress conditions. This was attributed to the activation of the biosynthesis for the free proline and the antioxidative status (total phenolic and flavonoid contents, DPPH activity, enzymes of CAT, and GR). The other cultivars exhibited lower values in these parameters compared to the tolerant cv., indicating their lesser capacity for salinity tolerance. The results indicated that the cv.‘Titan RX’could potentially be utilized to generate tall fescue crops that can cope with salinity stress conditions. |
