| Abstract/Contents: | "Increased restrictions on the use of potable water for irrigation purposes increased salt water intrusion into ground water mandate continued development and evaluation of salt tolerant turfgrasses. The purpose of this study was to document response of eight warm-season turfgrasses to solution cultures differentially salinized with synthetic sea water. A sea salt mixture was added to half-strength nutrient solution to provide six salinity treatments ranging from 1.4 to 42.6 dS m-1. A split plot design with five replications was utilized to study salinity as a main plot effect and grass as a sub plot effect. Turfgrasses differed markedly in salt tolerance. Based on inverse regression analyses, the most salt tolerant grasses were 'Emerald' zoysiagrass (Zoysia spp. Willd.), FSP-3 Seashore paspalumgrass (Paspalum vaginatum Swartz.), and 'Tifway' bermudagrass [Cynodon spp. (L.) Rich.]. Fifty percent top growth reductions were effected at 37.0, 34.6, and 33.0 dS m-1, respectively. Grasses with good salt tolerance were FSP-1 Seashore paspalumgrass, 'Tifway II' bermudagrass, 'Floralawn' St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze]. Fifty percent yield reductions were effected at 27.9, 24.0, and 22.1 dS m-1, respectively. Centipedegrass [Eremochloa ophiuroides (Munro) Hack.] and 'Argentine' bahiagrass (Paspalum notatum var. saurae Parodi) were extremely salt sensitive. Fifty percent yield reductions were effected at 9.2 dS m-1. Salinity differentially affected tissue content of Ca, Cl, Cu, K, Mg, Mn, Na, P, and Zn but had no affect on Fe. Sodium and Cl increased in all grasses except for Emerald zoysiagrass where increased salinity had no affect on Cl levels. In general, other nutrients decreased with increased salinity except for Cu, Mn, and Zn which remained unchanged in three out of six grasses." |
