Turfgrass Responses and Rootzone Media Characteristics as Affected by Salinity
Utilization of salt-tolerant species or cultivars is one the most effective methods to address salinity problems in turfgrass management. The relative salt tolerance in 26 commercial creeping bentgrass (Agrostis stolonifera) cultivars during germination was studied. Final germination rate (FGR) and...

Utilization of salt-tolerant species or cultivars is one the most effective methods to address salinity problems in turfgrass management. The relative salt tolerance in 26 commercial creeping bentgrass (Agrostis stolonifera) cultivars during germination was studied. Final germination rate (FGR) and daily germination rate (DGR) decreased as salinity levels increased; however, DGR was more sensitive to salinity stress. Substantial differences in salt tolerance were observed in bentgrass cultivars, with 'Declaration', 'Seaside II', 'T-1 ', and 'Bengal' being the most salt-tolerant (averaged predicted salinity level causing 50% reduction of DGR [PSLD] = 8.2 g L -1 NaCl) and 'Tyee', 'Kingpin'. and 'SRI 150' being the most salt-sensitive (averaged PLSD = 6.5 g L -1 NaCl). Relative salinity tolerance in four populations of prairie junegrass (Koeleriu macrantha) collected from Colorado, Minnesota, Nebraska, and North Dakota and two improved turf-type cultivars from Europe ('Barleria' and 'Barkoel') was determined and compared to Kentucky bluegrass (Poa pratensis), perennial ryegrass (Lolium perenne), sheep fescue (Festuca ovina), hard fescue (F. brevipila), and tall fescue (F. arundinacea).
