“…Our results indicated that salinity levels of 3.0 dS/m and lower had no negative affect on germination of any cultivars tested ( Table 2). These results are contrary to findings of Harivandi et al (9), who reported a significant reduction in germination of weeping alkaligrass cv. Fults, perennial ryegrass cv.…”

Germination of warm‐ and cool‐season turfgrasses was assessed at salinity levels commonly found in recycled irrigation water. Cool‐season grass seeds included in the study were Thermal Blue hybrid bluegrass [Poa arachnifera (Torr.) × pratensis (L.)]; Barlexas II, Southeast, and Tar Heel II tall fescue [Festuca arundinacea (Schreb.)]; Brightstar SLT and Catalina perennial ryegrass [Lolium perenne (L.)]; Salty and Fults alkaligrass [Puccinellia distans (Jacq.)]; and Dawson red fescue [Festuca rubra trichophylla (L.)]. Warm‐season grass seeds used in the study were bermudagrass Numex Sahara, Princess 77, and Transcontinental [Cynodon dactylon (L.)]; Companion zoysiagrass [Zoysia japonica (Steud)]; and Seaspray seashore paspalum [Paspalum vaginatum (Swartz)]. Each grass was incubated at salinity levels from 0.6 to 3.0 dS/m. Germination was considered successful upon radicle emergence and the first leaf growing past the coleoptile. Despite species and cultivar variation in germination success, germination was not inhibited in any of the tested cultivars at the salinity levels used in this study, suggesting that germination may not be the most salt‐sensitive stage in turfgrass development.

“…For many grass types this perception was validated in our experiment. Alkaligrass (1,6,7,9,12), creeping bentgrass (12,13), and the fescues (10,12) are considered moderately tolerant to tolerant of salinity and were highly tolerant to tolerant of rapid blight in our experiments. Several of the grasses considered very sensitive to salinity, such as colonial (5,12,13) and velvet (13) bentgrasses as well as the annual and rough bluegrasses (2), were also highly susceptible to rapid blight.…”

Forty‐nine different cool‐season grass cultivars representing 24 species were tested for their tolerance to the causal agent of rapid blight, Labyrinthula spp. Seeds of each grass were sown in 7.6‐cm pots and grown in the greenhouse. Plants were watered daily with deionized water for three weeks, then with artificial sea water at a concentration of 3.5 deciSiemens per meter. Experimental design was a randomized split‐plot with four replications where treatment (inoculated or non‐inoculated) was the main‐plot factor and cultivars were the sub‐plot factor. The entire experiment was replicated twice. Bulk inoculum of five Labyrinthula isolates was prepared by growing isolates on modified serum seawater agar for four days, adding colonized agar plugs to serum broth and vortexing. Cell counts of the bulk inoculum at 1.4 × 105 per ml were used for each inoculation. Plants in each pot were inoculated with 1 ml of inoculum placed on leaf tissue in the form of droplets from a syringe after wounding by trimming with scissors. Plants were rated for percent of diseased foliage. A high degree of susceptibility was observed in cultivars of rough bluegrass (Poa trivialis L.), colonial (Agrostis capillaris L.) and velvet bentgrasses (Agrostis canina L.), and perennial ryegrass (Lolium perenne L.) while certain cultivars of alkaligrass (Puccinellia distans (Jacq.) Parl.), slender creeping red fescue (Festuca rubra spp. littoralis (G. F. W. Meyer) Auquier), and creeping bentgrass (Agrostis stolonifera L.) appear to have moderate levels of tolerance.

Rapid blight, caused by Labyrinthula terrestris (D. W. Bigelow, M. W. Olsen, and Gilb.), occurs on cool‐season grasses in arid and coastal regions of the USA with elevated irrigation salinity. The impacts of irrigation salinity and cultivar salinity tolerance on rapid blight were examined in greenhouse experiments. Four cultivars each of Kentucky bluegrass (Poa pratensis L.), perennial ryegrass (Lolium perenne L.), and slender creeping red fescue (Festuca rubra spp. littoralis (G. F. W. Meyer) Auquier), known to differ in rapid blight susceptibility, were irrigated daily with solutions of 0.2, 1.3, 2.5, 3.6, and 4.8 dS/m, with or without inoculation with L. terrestris. Treatment effects were assessed by rating chlorotic leaf tissue and calculating area under the leaf chlorosis curve (AULCC). Rapid blight had little effect on AULCC of any grass at ≤ 1.3 dS/m. Slender creeping red fescues showed little AULCC due to rapid blight even at ≥ 2.5 dS/m. Perennial ryegrasses and Kentucky bluegrasses had substantial rapid blight‐induced AULCC at ≥ 2.5 dS/m. Leaf chlorosis due to rapid blight was less and slower to develop in ‘North Star’ Kentucky bluegrass and ‘Hawkeye’ and ‘Peregrine’ perennial ryegrasses than in other cultivars of these species. Leaf chlorosis due to salinity of 4.8 dS/m without inoculation correlated well with leaf chlorosis due to rapid blight at 2.5 dS/m, suggesting mechanisms imparting salinity and rapid blight tolerance may be similar. Irrigation water management practices reducing rootzone salinity and selection of tolerant species and cultivars are recommended to lessen rapid blight.
