Regional Optimization of Roadside Turfgrass Seed Mixtures 

Status:  Complete
Report Date:  01/24/2019

Summary:

Varieties from fifteen turfgrass species were tested in salt, heat and ice stress protocols. Analysis of color and cell membrane stability yielded recommendations for salt- and heat-resistant turfgrasses. Results from ice-stress trials were inconclusive. Researchers recommended a mixture of six tested cultivars, including bluegrasses, alkaligrass and fescues, for a field study of year-round performance alongside roadways.
