The tolerance of creeping bentgrass characterizes the crop's adaptation to abiotic stresses, such as salinity, temperature extremes, and herbicide exposure, and is assessed through physiological indicators and the maintenance of turf quality.

where this is mentioned in the description.
When assessing the salt tolerance of creeping bentgrass, hydroponic cultivation methods are used with a stepwise increase in NaCl concentration, measured in dS/m. Key indicators of damage include reductions in shoot and root dry matter, changes in the percentage of viable cover, and the level of electrolyte leakage. Resistant genotypes are capable of functioning at salt concentrations of up to 8–12 dS/m, whereas sensitive cultivars show signs of senescence at significantly lower stress levels.
Tolerance to herbicides is determined through injury threshold values (TI25) and shoot biomass reduction (GR50), while thermal stability is evaluated using the chlorophyll fluorescence parameter Fv/Fm. A high level of tolerance is critical for maintaining turf density and aesthetic quality, preventing degradation, and ensuring rapid recovery following exposure to adverse environmental factors.
