“…In contrast, tall fescue was the most resistant species in all four seasons of the year and had no dormancy period. Liu et al [45] showed that tall fescue had higher heat and cold resistance than bermuda grass. The reason might be that tall fescue accumulates higher proline and H2O2 content as an antioxidant than bermuda grass after heat treatment.…”

Turfgrasses are essential landscape plants with social, environmental, and aesthetic services for urban ecosystems. However, more is needed to know how to establish them so that they can benefit from their ecosystem services in urban environments. This research examined some quality and morphological and physiological factors for the establishment and social and environmental service assessment of three warm-season turfgrasses, including Kikuyu grass (Pennisetum clandestinum), bermuda grass (Cynodon dactylon), and buffalo grass (Buchloe dactyloides), compared to the cool-season grass of tall fescue (Festuca arundinacea Schreb.). The experiment was split-plot in time, based on a randomized complete block design with eight replications. The main plot was the season with four levels, and the subplot was the four turfgrass species types. The results indicated that seasons and turfgrass types and their interaction significantly impacted most measured variables (p ≤ 0.01). Some quality measurements like turf density, color, texture, coverage, and quality after clipping and establishment confirmed the superiority of Buchloe dactyloides over the other species. Also, kikuyu grass showed higher turfgrass density, more potential for weed control, and higher coverage and growth rate but also showed invasiveness features. Tall fescue had the lowest visual aesthetic compared with the other turfgrass species. Warm-season turfgrasses adaptable to the ecology of the region should be used compared to tall fescue to achieve better turfgrass quality and social and ecosystem services for the sustainable development of arid urban environments.

Cool‐season turfgrasses widely used on golf courses, athletic fields, and other landscapes are environmentally and economically important, but they are functionally and aesthetically damaged under prolonged exposure to high temperatures because of their sensitivity to heat stress. Because the consequences of climate change include elevated global temperatures, it is necessary to understand mechanisms underlying heat tolerance in cool‐season turfgrasses to improve heat tolerance and maintain high‐quality turf during the summer, when heat stress is most severe. This paper identifies major metabolic pathways associated with genes differentially expressed in heat‐tolerant cultivars or species of different turfgrasses by overviewing research from studies using comparative transcriptomics, proteomics, and biotechnological approaches and provides insight into progress toward elucidating the genetic and molecular factors regulating heat tolerance in cool‐season turfgrasses. Key molecular factors and genes associated with heat tolerance in cool‐season turfgrasses include those in the following cellular and metabolic processes or pathways: (1) cell cycle and DNA synthesis, replication, stability, and binding factors; (2) heat shock proteins for stress protection and protease enzymes controlling protein degradation or turnover; (3) carbohydrate metabolism for chloroplast development, chlorophyll degradation enzymes regulating the stay‐green phenotype, photochemical efficiency, carboxylation, and cytochrome respiratory activities; (4) activation of antioxidant metabolism for oxidation protection; (5) modulation of lipid saturation and composition to maintain cellular membrane integrity; and (6) upregulation of secondary metabolism for stress defense. Understanding how these regulatory mechanisms cohesively operate during heat stress will facilitate the development of cool‐season turfgrass germplasm with greater heat tolerance through breeding and biotechnological methods.
