Abstract/Contents:"Traffic tolerant turfgrass is an essential characteristic for proper athletic field aesthetics and athlete safety. Tall fescue (Schedonorus arundinaceus Schreb.) is a cool-season turfgrass commonly utilized on athletic fields due to its traffic tolerance. The mechanisms associated with traffic tolerance are not well understood for tall fescue, therefore, identifying traffic tolerant characteristics would be beneficial for selecting future traffic tolerant varieties. The objective of this study was to identify morphological and anatomical characteristics of traffic tolerant and intolerant tall fescue varieties. Simulated traffic was applied to the 2018 National Turfgrass Evaluation Program (NTEP) tall fescue field plots at the Iowa State Horticulture Research Station in Ames, IA. Twenty-four simulated traffic events were applied to 132 varieties using a modified Baldree traffic simulator during August and September 2019-2021. The four most traffic/intolerant varieties were selected for evaluation based on the average final percent green cover at the conclusion of simulated traffic each year. Selected varieties were evaluated for morphological and anatomical characteristics. Evaluations included leaf width, leaf thickness, shoot density, intercellular void space, the maximum and final resistive force of 3-point-bending testing, and cell wall constituents measured through neutral detergent fiber analysis (NDF) acid detergent fiber analysis (ADF), and the percentage of lignin. Compared to traffic sensitive varieties, traffic tolerant varieties had wider leaves (3.53 vs. 2.73 mm), lower plant density (23.4 vs 38.6 plants 3cm-2), larger intercellular void space (29,532 vs. 10,051Āµm2), and greater maximum resistive force (0.607 vs 0.35 N) and greater final displacement force (0.531 vs. 0.288 N). The identification of these characteristics could be used as desirable selection criteria for future traffic tolerant varieties of tall fescue."
