Abstract/Contents:"Use of marginal quality waters for irrigation in arid and semi-arid regions has increased problems associated with maintaining acceptable quality turfgrass under saline conditions. Kentucky bluegrass (Poa pratensis L.) is considered to be salt sensitive. Information as to the relative salt tolerance of Texas bluegrass (Poa arachnifera Torr.) and certain Poa hybrids (P. pratensis x P. arachnifera) is unavailable. The purpose of this study was to examine growth and turf quality responses to salinity within and among Poa spp. Grasses tested included 5 Kentucky, 6 Texas, and 5 hybrid bluegrasses, and 4 Poa collections. Grasses were grown in the greenhouse in solution culture with salinity treatment levels ranging from 1 to 9 dS/m. Shoot growth was measured to derive threshold electrical conductivity (EC) and slope reduction parameters. Percent leaf firing relative to control plants was rated to determine decline in turf appearance. Threshold EC for shoot growth reduction ranged from 1 to 7 dS/m, 50% growth reduction EC from 4 to 9 dS/m, and slopes of growth reduction from 1 to 11%. Relative percent leaf firing at 5 dS m-1 ranged from > 90% to < 5%. Our results indicate significant variation in salinity tolerance within and among Poa spp. and hybrids. Identification and use of salt tolerant Poa genotypes in turfgrass breeding programs may improve salt tolerance in bluegrasses."
