In the sun-drenched landscapes of Antalya, Turkey, a quiet revolution is brewing in the world of turfgrass. Dr. S. Sever Mutlu, a researcher at the University of Akdeniz’s Department of Landscape Architecture, is leading a charge to broaden the genetic base of bermudagrass, a move that could have significant implications for the energy sector and beyond. Mutlu’s latest findings, published in the European Journal of Horticultural Science, delve into the intricate world of interspecific hybrids, offering a glimpse into a future where turfgrass is not just about aesthetics, but also about sustainability and energy efficiency.
Bermudagrass, a staple in warm-season lawns and sports fields, is facing an identity crisis. As climate change alters growing conditions and pests evolve, the need for more resilient and adaptable grass varieties has never been greater. Mutlu’s research focuses on two species: Cynodon dactylon, the common bermudagrass, and Cynodon transvaalensis, a lesser-known but hardy relative. By crossing these species, Mutlu aims to create interspecific hybrids that combine the best traits of both.
“The potential is enormous,” Mutlu explains, his eyes lighting up as he discusses the possibilities. “We’re talking about grass that can withstand drought, resist diseases, and even help reduce energy consumption in urban areas.”
The energy sector, in particular, stands to gain from these advancements. Turfgrass covers vast areas in urban landscapes, and its management—from mowing to irrigation—consumes significant energy. More resilient grass varieties could reduce the need for water and maintenance, lowering energy consumption and costs. Moreover, strategic planting of these hybrids could help mitigate the urban heat island effect, reducing the demand for air conditioning and further cutting energy use.
Mutlu’s work involves creating hybrids with varying ploidy levels—diploid and hexaploid, to be precise. Ploidy refers to the number of sets of chromosomes in a cell. By manipulating this, Mutlu can create grass varieties with unique traits. For instance, hexaploid hybrids might offer enhanced stress tolerance, while diploids could provide better seed production for easier propagation.
The implications of this research extend beyond the energy sector. Sports fields, golf courses, and even residential lawns could benefit from these hardy, low-maintenance grass varieties. Moreover, the techniques developed in this study could be applied to other turfgrass species, broadening the impact even further.
As Mutlu continues to refine his hybrids, the future of bermudagrass—and the landscapes it adorns—looks increasingly green and sustainable. The research, published in the European Journal of Horticultural Science, known in English as the European Journal of Horticultural Science, is just the beginning. It opens the door to a world where turfgrass is not just a decorative element, but a vital part of our sustainable future. The energy sector, in particular, should keep a close eye on these developments. The grass beneath our feet could soon be powering our cities in more ways than one.
