| Abstract/Contents: | "Seven turfgrass genotypes were evaluated for salt tolerance in a greenhouse for the purpose of identifying salt tolerant genotypes for residential and recreational use in arid and semi-arid regions where reclaimed water with relatively high salt levels can be used for irrigation. The genotypes were developed at the Texas A&M AgriLife Turfgrass Breeding Program and included Zoysia matrella Diamond, Z. japonica 'Palisades', three Z. matrella x Z. japonica hybrids (DALZ 1701, 1713, and 'Innovation'), and two Z. minima x Z. matrella hybrids (DALZ 1309 and 'Lazer'. Treatments included a control and two saline treatments representing moderate and high salt levels with electrical conductivities (EC) of 1.3, 5.0, and 10.0 mS cm-1, respectively. At the end of eight weeks of treatments, the relative (percent control) shoot dry weight (DW) was greatest in 'Diamond' when treated with EC10, and the relative root DW was greatest in 1309 when treated with EC5. A cluster analysis based on the relative tissue dry weight identified 'Diamond', 1309, and 1713 as the most salt tolerant genotypes. Additionally, the green leaf area (GLA) index of 'Diamond' and 1713 were 98.8% and 100%, respectively, indicating excellent visual appearance under high salt levels. Bi-weekly clipping DW showed that 'Diamond' continued to produce biomass throughout the duration of the study under the EC10 treatment. Sodium and chloride content in the shoot tissue of the seven turf genotypes ranged from 1.70 to 15.68 mg gDW-1, and 5.65 to 25.18 mg gDW-1, respectively, and did not correlate with salinity tolerance. Taken together, the genotypes 'Diamond' and 1713 were determined to be the most salt tolerant and recommended for use with reclaimed irrigation." |
