The interest in saline-tolerant turfgrasses continues as the availability of potable water for irrigation decreases. Pure-Seed Testing, Inc. conducted turf survival tests in greenhouse saltwater baths, to determine which varieties tolerate high levels of salinity. Different levels were used for the various turfgrass species, depending on their inherent salt tolerance. Varieties that had 50% or greater survival rate over the length of the study were deemed qualified to receive the salt tolerance icon.

Pure-Seed Testing, Inc. identifies plants with saline tolerance for use in breeding projects and to find existing varieties that have natural high salt tolerance. Using a synthetic ocean salt, a salt bath was created containing six different salts as well as minor elements. Plants were placed in the baths in each of four replications for a specified period of time. Percent survival was calculated, based on the number of plants maintaining green colour vs. number of dead plants subjected to a salt bath.
