“…This study also did not address the role of light intensity or photoperiod on chilling response. There is evidence that increasing photoperiod alone can induce measureable growth in bermudagrass even under low light intensity and decreasing temperature (Esmaili and Salehi, 2012;Sinclair et al, 2003). The use of artificial light sources has become increasingly popular for stadium fields and the relative importance of light or temperature on fall color retention and lipid composition warrants additional study.…”

Cell and plastid membranes play a critical role in plant response to chilling stress. Fall color retention (chilling tolerance) of bermudagrass (Cynodon sp.) is known to vary with cultivar and management practices. A growth chamber study was conducted to characterize the lipid composition of three bermudagrasses in response to chilling stress. The grasses selected were ‘Tahoma 31’ (chilling-sensitive) and ‘Tifway’ (chilling-tolerant) interspecific hybrid bermudagrass (C. dactylon × C. transvaalensis) and ‘Celebration’ common bermudagrass (C. dactylon), which served as an internal standard. Plants were subjected to simulated fall conditions defined as an 8/2 °C (day/night) temperature regime with 10-hour photoperiod and evaluated for chilling response for 42 days before allowing plants to enter an apparent dormancy. Plant leaves were sampled for lipidomics analysis at 0, 14, and 42 days of chilling treatment (DOT) and again after 40 days of recovery from dormancy (during which temperatures were adjusted to mimic average spring conditions for Oklahoma). ‘Tifway’ demonstrated the lowest electrolyte leakage (EL) and visual discoloration at 42 DOT, while ‘Tahoma 31’ had the greatest EL and discoloration on the same date, and ‘Celebration’ was intermediate of the two. Prolonged exposure to chilling stress generally increased digalactosyldiacylglycerol and phosphatidylcholine (PC) content and decreased monogalactosyldiacylglycerol (MGDG) content, with ‘Tahoma 31’ showing the greatest increase in PC and decrease in MGDG. The double bond index, an indicator of fatty acid unsaturation, was greatest in ‘Tifway’ at 42 DOT. Each cultivar increased in fatty acid unsaturation, with Tifway demonstrating the greatest increase in MGDG unsaturation. Multivariate discriminant analysis identified six individual lipid species that contributed most to the cultivar response to chilling. These findings suggest unsaturation level of plastid lipids, particularly MGDG, is important for chilling tolerance and therefore fall color retention of bermudagrass. Furthermore, this study provides evidence that chilling tolerance can be negatively associated with freezing tolerance in bermudagrass.

“…is frequently used in the transition zone where it can provide an excellent surface for golf course fairways and athletic fields. However, these species have a tendency to be injured or killed by low temperatures in the transition zone (Munshaw et al, 2006;Anderson et al, 2007;Esmaili and Salehi, 2012).…”

Agronomic behaviour of some Cynodon dactylon ecotypes for turfgrass use in the Mediterranean climate

et al. 2015

In Italy, the expansion of turfgrasses is limited by the lack of suitable species for cultivation in the Mediterranean climate. With this view, Mi.Te.A.Med. (Turfgrass improvement in the Mediterranean climate) research project was developed with the main purpose to find out and agronomically characterise native turfgrass species of Southern and Central Italy and to compare them with some commercial cultivars. During the first step of the research, 11 sites from 6 regions of Southern and Central Italy were identified. In these sites 24 ecotypes of Cynodon dactylon L. (Pers.) were collected and their habitus, phenology plus some biometric parameters have been determined. During the two years of research both botanic and agronomic characterisation of the collected C. dactylon ecotypes and their comparison with 3 commercial cultivars (Panama, Transcontinental and Yukon) was carried out. In the first year the colour loss interval was assessed. In the second year, colour index was measured by an electronic colorimeter, weekly growth rate was measured by a turfmeter, turf quality and ground cover percentage were assessed by visual estimate. Some native accessions showed behaviour similar to commercial cultivars while an ecotype from the Abruzzo region showed better results compared to the commercial cultivars for several quality indices.

“…; White and Schmidt 1990;Munshaw et al 2006). The photoperiod was increased during months with short day lengths in order to shorten the winter dormancy of bermudagrass (Esmaili and Salehi 2012). The application of fertilization (Goatley et al 1994;Trenholm et al 1998), winter turf covers (Goatley et al 2005) and spring scalping (Rimi et al 2011) has also been used to facilitate green up earlier.…”

Zoysiagrass (Zoysia spp.) is warm season grass used for lawns, golf courses and athletic fields. Although it has better low temperature tolerance compared to other warm season grasses, its longer dormant period than cool season grasses prevents its wide usage in transitional and cooler climate zones. This study analyzed the relationships among low temperature tolerance, green color changes during the fall and spring and the dormant period length among seven Zoysia japonica Steud. cultivars and accessions: two cultivars, four Chinese accessions and one Japanese accession. A relationship between low temperature tolerance and color changes due to dormancy and re‐greening up was examined. Plant samples from the tested Z. japonica were cooled to between −8 and −16°C to measure the lethal temperatures at which 50% of plants died (LT50). These LT50 ranged from −7.3 to −10.1°C, with Lanyin No. 3 having the poorest low temperature tolerance. In the field, the color changes from green to brown for the whole plant in the fall and from brown to green in the spring occurred within 15–20 days as determined by digital analysis from fall 2008 to spring 2010. The fall colors changes (going dormant) on November 8, 2008 and November 7, 2009 were positively correlated with the LT50 (r = 0.824 and 0.823, respectively). The spring colors changes (green‐up) on April 24, 2009 and May 19, 2010 were negatively correlated with the LT50 in both 2009 (r = −0.878) and 2010 (r = −0.869). The dormant period length in 2008–2009 was positively correlated (r = 0.765) with the LT50. This study demonstrated that Z. japonica with poor low temperature tolerance has better green‬‬ retention in the fall but less green color in the spring‬‬. Furthermore, Z. japonica, which became dormant later underwent green up later and had a longer dormant period, mainly due to slower green up in spring.‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬
