“…Among all cultivars studied, seashore paspalum exhibited the best visual quality during all three growing seasons, while saltgrass had the lowest quality (Table 6). Our findings support those of Duncan and Carrow (2000), Berndt (2007), and Lee et al (2005) who reported a high salinity tolerance in seashore paspalum and consequently a high turf quality in saline soils. Low quality ratings for inland saltgrass could not be attributed to salt stress, as water quality had no effect on turf performance in our study (Table 5).…”

A study was conducted in New Mexico from 2005 to 2007 to investigate the effects of two potable water‐saving strategies, irrigating with saline water and using subsurface systems, on changes in rootzone salinity and quality of nine warm‐season turfgrasses. Plots were irrigated using either sprinklers or subsurface drip with water of 1 of 3 salinity levels (0.6, 2.0, and 3.5 dS m−1). Plots were rated monthly for quality during the growing seasons and bi‐annually for spring and fall color. Soil samples were collected bi‐annually (June and November) and analyzed for electrical conductivity (EC), Na, and sodium adsorption ratio (SAR) at depths of 0 to 20 and 50 to 60 cm. Electrical conductivity and Na values in 0 to 20 cm peaked in June of 2005 and 2006 and dropped to lower levels after the summer rainy season. With the exception of moderately saline irrigated plots in 2005, summer EC did not differ between drip and sprinkler irrigated plots for any of the three water qualities. Electrical conductivity, Na, and SAR at a rootzone depth of 0 to 20 cm were highest in June 2006 reaching 4.7 dS m−1, 1024 mg L−1, and 16.1, respectively. For most of the grasses tested, EC, Na, or SAR values showed no significant relationship with turf quality. Drip irrigation resulted in earlier green‐up than sprinkler irrigation but had no effect on summer quality or fall color retention. Most of the warm season grasses included in this study maintained an acceptable quality level when drip‐irrigated with saline water.

“…However, a chemical analysis of the water used in this study (Table ) did not reveal any significant levels of constituents that might explain the increased growth or quality. Overall, salinity levels measured throughout the course of our experiment are within the genetic tolerance levels of the grasses investigated and should have no impact on their quality (Berndt, ). More research is needed to investigate why saline groundwater resulted in higher turf quality than the potable water.…”

“…Water quality did not affect green‐up of turfgrasses. Soil test results (Table ) showed that EC and SAR in March and June never reached levels that are considered detrimental for seashore paspalum or bermudagrass (Berndt, ). These results were similar to findings of Sevostianova et al.…”

A 3‐year study was conducted at New Mexico State University in Las Cruces, NM, to investigate the effects of different fertilization treatments on turf performance when water conservation strategies are applied. These strategies include the use of non‐potable saline irrigation water and the use of efficient subsurface irrigation systems. Two low water use warm‐season grasses, “Princess 77” bermudagrass (Cynodon dactylon L.) and “Sea Spray” seashore paspalum (Paspalum vaginatum O. Swartz), were irrigated with either potable [Electrical Conductivity (EC) = 0.6 dS/m] or saline (EC = 3.1 dS/m) water from either an overhead or a subsurface drip irrigation (SDI) system. Four different fertilizers, liquid slow release, granular slow release, granular urea and liquid urea, were applied at two rates: 10 and 20 g N m−2 year−1 for “Sea Spray” and 20 and 30 g N m−2 year−1 for “Princess 77.” Spring green‐up, summer quality and fall colour retention were determined using digital image analysis, visual quality ratings and normalized difference vegetation index. Generally, subsurface drip‐irrigated grasses were slower to green‐up than overhead irrigated ones. “Sea Spray” irrigated from the SDI system took 18, 28 and 15 days longer to reach 80% green cover in 2010, 2011 and 2012, respectively, than their sprinkler‐irrigated counterparts. The combination of “Princess 77” and overhead irrigation reached 80% green cover 35 (in 2010), 34 (in 2011) and 12 (in 2012) days faster than SDI‐irrigated “Princess 77.” Fertilization rate and type had no effect on summer turfgrass quality of “Princess 77” irrigated from a sprinkler system throughout the research period reaching ratings of greater than 7 during all 3 years. Similar results were observed for “Princess 77” irrigated from a SDI system during 2010 and 2011. Summer quality of sprinkler‐irrigated “Sea Spray” was negatively affected by liquid fertilization. During two of three summers, visual quality of plots fertilized with either liquid slow release or liquid urea was lower than “Sea Spray” fertilized with granular fertilizer. Further research is needed to investigate the effect of fertilization on bermudagrass and seashore paspalum over a wider nitrogen range including both granular and foliar products.

“…This species can grow in high salt water concentrations and waterlogged environments, and can be used for bioremediation of contaminated (e.g., heavy metals and organic chemicals) or unproductive soils (Wang et al, 2006) and for forage production (Lee et al, 2008). In recent years, seashore paspalum has been used as a turfgrass on golf courses and other sports fields (Berndt, 2007). Some ecotypes display a wide range of tolerance to salt, drought, flooding, nitrogen level, soil conditions, soil pH, low mowing height, and extreme temperatures (Trenholm et al, 2000) which are desirable qualities for turfgrass.…”

2679ReseaRch D evelopment of genetic tools for warm-season turfgrasses is in its infancy and there is limited reference to marker-trait associations in warm-season turfgrasses. Heckart et al. (2010) reported that sethoxydim resistance (an herbicide) is conferred by a single nucleotide polymorphism in the acetyl coenzyme A carboxylase (ACCase) gene in two seashore paspalum mutants generated by tissue culture. The warm-season turfgrass species with the largest number of molecular tools are bermudagrass and zoysiagrass which have a collection of SSRs (Cai et al., 2005;Harris-Shultz et al., 2010;Harris-Shultz et al., 2011b;Kamps et al., 2011) and a genetic map (Bethel et al., 2006;Cai et al., 2005;Harris-Shultz et al., 2010). Twentyfour polymorphic SSRs were identified from sequencing species of genus Eremochloa (Harris-Shultz et al., 2011a), to which centipedegrass belongs. At present, the other warm-season turfgrasses, Saint Augustine grass, seashore paspalum, and bahiagrass species lag ABSTRACT The increasing use of secondary water sources for irrigation, which is highly linked to salinization, creates a demand for salt tolerant turf. Seashore paspalum (Paspalum vaginatum Swartz) is a warm-season turfgrass that survives in sand dunes along coastal sites, brackish ponds, and in estuaries. Some seashore paspalum accessions and cultivars are far more salt tolerant than others. To identify genetic regions that are associated with salt tolerance, molecular tools must be developed. In this study, genomic libraries, enriched for microsatellites, were generated using the salt tolerant accession HI33. High throughput sequencing and subsequent assembling of these libraries resulted in 18,967 contigs and 158,595 singletons. The number of simple sequence repeats (SSr) detected in contigs and in singletons was 3511 and 31,949, respectively, and the number of primer sets designed within each group was 937 and 1667. A total of 80 SSr markers, including five markers previously developed, were used to assess genetic relationships among 18 Paspalum accessions. Two major clusters were identified from the seashore paspalum accessions. Accessions that are likely polyploids, all with coarse leaves, grouped together whereas accessions with fine-to mid-fine leaves formed a second group. Furthermore, 33 seashore paspalum SSr markers cross-amplified in bahiagrass (Paspalum notatum Flugge) and these markers can be a useful tool in this species.
