Bermudagrass ( spp.) is a common turfgrass found in parks, landscapes, sports fields, and golf courses. It is also grown as a forage crop for animal production in many countries. Consequently, bermudagrass has significant ecological, environmental, and economic importance. Like many other food crops, bermudagrass production also faces challenges from various abiotic and biotic stresses. In this review we will focus on abiotic stresses and their impacts on turfgrass quality and yield. Among the abiotic stresses, drought, salinity and cold stress are known to be the most damaging stresses that can directly affect the production of turfgrass worldwide. In this review, we also discuss the impacts of nutrient supply, cadmium, waterlogging, shade and wear stresses on bermudagrass growth and development. Detailed discussions on abiotic stress effects on bermudagrass morphology, physiology, and gene expressions should benefit our current understanding on molecular mechanisms controlling bermudagrass tolerance against various abiotic stresses. We believe that the rapid development of transcriptomics and proteomics, as well as bermudagrass stable transformation technologies will promote the production of new bermudagrass cultivars with desirable tolerance against abiotic stresses.
狗牙根（狗牙根属）是一种常见的草坪草，见于公园、景观区、运动场和高尔夫球场。在许多国家，它也作为饲料作物种植用于动物生产。因此，狗牙根具有重要的生态、环境和经济意义。与许多其他粮食作物一样，狗牙根生产也面临各种非生物和生物胁迫带来的挑战。在本综述中，我们将重点关注非生物胁迫及其对草坪草质量和产量的影响。在非生物胁迫中，干旱、盐度和冷胁迫是已知对全球草坪草生产有最直接影响的最具破坏性的胁迫。在本综述中，我们还讨论了养分供应、镉、涝害、遮荫和磨损胁迫对狗牙根生长发育的影响。对非生物胁迫对狗牙根形态、生理和基因表达影响的详细讨论，应有助于我们目前对控制狗牙根对各种非生物胁迫耐受性的分子机制的理解。我们相信，转录组学和蛋白质组学的快速发展以及狗牙根稳定转化技术将促进培育出对非生物胁迫具有理想耐受性的新狗牙根品种。
