| Abstract/Contents: | "Turfgrass species and cultivars exhibit significant variation in salinity tolerance; however, underlying mechanisms of salinity tolerance in turfgrasses have not been fully elucidated. The objectives of this study were to compare interspecific variation in salinity tolerance for six cool-season turfgrass species and determine whether changes in antioxidant activities were associated with the genetic variation in salinity tolerance. Plants of perennial ryegrass (Lolium perenne cv. Palmer III), creeping bentgrass (Agrostis stolonifera cv. L-93), colonial bentgrass (Agrostis capillaris cv. Tiger), velvet bentgrass (Agrostis canina cv. Greenwich), Kentucky bluegrass (Poa pratensis cv. Diva), tall fescue (Festuca arundinacea cv. Rebel Jr.) and alkaligrass (Puccinellia distans cv. Fults) were subjected to salinity stress by irrigation with saline water at an electrical conductivity of 12 dS m-1 in a growth chamber. The results from measurements of turf quality, leaf relative water content, and membrane stability expressed as electrolyte leakage demonstrated that the six species varied in salinity tolerance, with alkaligrass and tall fescue being most tolerant, perennial ryegrass, Kentucky bluegrass, and creeping bentgrass being moderately tolerant, and colonial and velvet bentgrass being most sensitive to salinity stress. Salinity stress reduced membrane stability and caused membrane lipid peroxidation, but alkaligrass and tall fescue were able to maintain significantly higher activities of antioxidant enzymes (superoxide dismutase, catalase, and ascorbate peroxidase) relative to other species, particularly colonial and velvet bentgrass. These results suggested that superior salinity tolerance in cool-season turfgrass species could be associated with greater activities of antioxidant enzymes, protecting cellular membranes from oxidative damages induced by salinity." |
