“…A range in above‐ and belowground morphological traits were observed in the current study. Previously, Ebdon and Petrovic (1998) and Głąb, Szewczyk, Dubas, Kowalik, and Jezierski (2015) reported the importance of morphological traits of leaf width and area in selection for turfgrass stress resistance. Although total leaf area was not assessed in the current study, no clear association between leaf traits and drought resistance were observed.…”

The objective of this study was to compare drought resistance in a range of seashore paspalum (Paspalum vaginatum Sw.) genotypes and identify associated morphological and physiological traits. Fifteen genotypes were grown in growth chamber conditions and exposed to well‐watered and drought‐stress treatments. Genotypes ‘Seaisle1’ and PI647891 were consistent top performers, whereas ‘Seastar’ and PI614680 performed poorly as measured by turf quality, percentage green cover, and relative water content when exposed to drought stress. Observed levels of drought resistance had no significant relation with morphological traits such as leaf width and internode length but were found to be associated with various physiological traits. Drought resistant genotypes were able to better maintain membrane stability, photosynthesis, and had greater water use efficiency compared with sensitive genotypes. Earlier osmotic adjustment at 7 d via faster osmolyte accumulation was a significant contributor to performance during drought. Drought‐resistant Seaisle1 and PI647891 had deeper roots and greater root length density than drought sensitive ‘Seastar’ and PI614680. Results showing variability in the level of drought resistance and associated mechanisms in understudied seashore paspalum genotypes could facilitate future breeding efforts for developing drought‐resistant turfgrass cultivars.

“…Traffic stress plays a role in affecting the morphological and physiological features of turfgrass species. Tolerance to this stress is associated with a high vascular bundle number, wide leaves, high leaf angle, and high root length density [169,170]. Physiological changes in turfgrass species were detected under traffic stress, such as a decrease in RWC, shoot density, root length, leaf Chl concentration, non-structural carbohydrates content, and POD activity, while the cell membrane permeability was increased in both warm-season and cool-season turfgrass species after traffic stress treatment [171][172][173].…”

Mechanisms of Environmental Stress Tolerance in Turfgrass

et al. 2020

Turfgrasses constitute a vital part of the landscape ecological systems for sports fields, golf courses, home lawns and parks. However, turfgrass species are affected by numerous abiotic stresses include salinity, heat, cold, drought, waterlogging and heavy metals and biotic stresses such as diseases and pests. Harsh environmental conditions may result in growth inhibition, damage in cell structure and metabolic dysfunction. Hence, to survive the capricious environment, turfgrass species have evolved various adaptive strategies. For example, they can expel phytotoxic matters; increase activities of stress response related enzymes and regulate expression of the genes. Simultaneously, some phytohormones and signal molecules can be exploited to improve the stress tolerance in turfgrass. Generally, the mechanisms of the adaptive strategies are integrated but not necessarily the same. Recently, metabolomic, proteomic and transcriptomic analyses have revealed plenty of stress response related metabolites, proteins and genes in turfgrass. Therefore, the regulation mechanism of turfgrass’s response to abiotic and biotic stresses was further understood. However, the specific or broad-spectrum related genes that may improve stress tolerance remain to be further identified. Understanding stress response in turfgrass species will contribute to improve stress tolerance of turfgrass.

“…Simulated traffic replicates the horizontal and vertical forces that affect both the soil and turfgrass in a reproducible manner, which results in soil compaction and shearing of the turfgrass [1,7,8]. Traffic tolerant turfgrass genotypes have been associated with a more vertical leaf angle, wider leaf blades, greater leaf cell wall constituents, increased number of vascular bundles, high root length density, larger intercellular void spaces, and increased leaf antioxidant activity [9][10][11][12][13]. Sports turf managers have relied on effective fertilization programs to help ensure field safety and performance; however, in recent years, sustainable management practices and the utilization of bio-stimulants, such as humic substances, have garnered interest within the turfgrass industry [2].…”

Sports field traffic tolerance is critical for offering athletes a safe playing surface and adequate turfgrass performance. Humic substances act as bio-stimulants that could enhance turfgrass traffic tolerance by increasing turfgrass efficiency, which could be due to increased root growth, antioxidant activity, and/or physiological health. A two-year field experiment was conducted on a Kentucky bluegrass (Poa pratensis L.) sports field to investigate if incorporating humic substances with fertilizers could improve turfgrass traffic tolerance and performance, and enhance turfgrass recovery after traffic. Treatments included humic-coated urea, poly-coated humic-coated urea, synthetic fertilizer with black gypsum (two application timings), black gypsum, stabilized nitrogen, poly-coated sulfur-coated urea, urea, and a nontreated control. The addition of humic substances to fertilizer treatments did not result in improve traffic tolerance and performance. Fertilizer treatments did not lead to an effect on soil moisture, surface hardness, and shear strength. Turfgrass recovery varied between years. In 2020, the second year of the experiment, four applications of fertilizers increased turfgrass recovery by 136% relative to the nontreated. Furthermore, incorporating humic substances did not result in enhanced turfgrass recovery compared to fertilizers alone. Overall, applications of fertilizers with humic substances could improve turfgrass recovery from traffic compared to fertilizers alone, but results were variable between years.
