Abstract/Contents:"Bermudagrass (Cynodon spp.), a salt tolerant species, is frequently grown on saline soil. However, new cultivars or accessions used in breeding programs may further increase salt tolerance. Therefore, salt tolerance of the cultivar Tifway II and the accessions Tifton 10 (obtained from China) and Tifton 86 (obatined from Israel) was tested. Plants were grown in the greenhouse in 0.05 cubic meter pots filled with Pachappa fine sandy loam (mixed, thermic, Mollic Haploxeralf). Four salinity treatments were imposed by irrigating with waters salinized with NaCl and CaCl2 (1:1, by weight). Electrical conductivities of the irrigation waters were 0.9, 6.2, 11.7, and 17.2 dS.m-1. Top growth was measured at nine consecutive harvests. Relative top growth of Tifton 10, 'Tifway II', and Tifton 86 was unaffected by soil salinity until the electrical conductivity of the saturated-soil extract (k(e)) exceeded 2.7, 8.4, and 10.3 dS.m-1, respectively. Each unit increase above these thresholds reduced yield of Tifton 10 by 2.3%, moderately tolerant, and 'Tifway II' by 2.8%, and Tifton 86 by 2.5%. These results place Tifton 10 in the moderately tolerant, and 'Tifway II' and Tifton 86 in the tolerant salt-tolerance categories."
