Relative Salinity Tolerance of 21 Turf-type Desert Saltgrasses Compared to Bermudagrass

Broadening the Horizons of Turf Bermudagrass

‘ST-5’, a Shade-tolerant Turf Bermudagrass

‘ST-5’ turf bermudagrass is an interspecific [Cynodon transvaalensis Burt-Davy · C. dactylon (L.)] shade-tolerant triploid (2n = 3x = 27 chromosomes) hybrid cultivar released cooperatively by the University of Georgia College of Agricultural and Environmental Sciences and the U.S. Department of Agriculture, Agricultural Research Service. ‘ST-5’ was selected in 1993 from 27,700 hybrids made in 1...

Effects of Trinexapac-Ethyl on the Salinity Tolerance of Two Ultradwarf Bermudagrass Cultivars

Studies on bermudagrasses (Cynodon spp.) have demonstrated variability in salinity response among species and cultivars. However, information on ultradwarf bermudagrass cultivars in relative salinity tolerance associated with trinexapac-ethyl (TE) [4-(cyclopropyl-hydroxy-methylene)-3,5-dioxocyclohexanecarboxylic acid ethyl ester], a cyclohexanedione type II plant growth regulator (PGR), remains...

Herbicides control annual winter weeds in bermudagrass turf

Weeds are commonly found in bermudagrass turf during the winter and early spring throughout the Southeastern United States whether this turf is used for lawns, parks, athletic fields or golf courses. Mild winter temperatures favor rapid growth of these annuals. When bermudagrass goes dormant in the fall after the first killing frost, it does not compete with germinating winter weeds. Bermudagra...

Physiological and Growth Responses of Six Turfgrass Species Relative to Salinity Tolerance

The demand for salinity-tolerant turfgrasses is increasing due to augmented use of effluent or low-quality water (sea water) for turf irrigation and the growing turfgrass industry in coastal areas. Experimental plants, grown in plastic pots filled with a mixture of river sand and KOSAS(R) peat (9 : 1), were irrigated with sea water at different dilutions imparting salinity levels of 0, 8, 16, 2...
