The performance of fine fescue (Festuca spp.) species and cultivars may differ by traffic form or the season of wear simulation. Two trials were initiated in 2012 to evaluate the effect of traffic form (abrasive wear vs. cleated traffic) and season of wear (spring, summer, or autumn) on 10 fine fescues seeded in North Brunswick, NJ. Plots were visually assessed for the fullness of turfgrass canopy (FTC) and leaf bruising. Verdure and soil physical properties were assessed after the last assessment period in the traffic form trial. Abrasive wear constantly reduced the FTC (14–30%) of fine fescues compare to the non-trafficked control, while the FTC of plots with cleated traffic was similar to the non-trafficked control towards the end of the study. Although both traffic forms caused soil compaction, cleated traffic resulted in a more compacted soil. Abrasive wear improved selection efficiency for fine fescues compared to cleated traffic. The FTC response of fine fescues cultivars interacted with the season of wear; thus, screening for fine fescues with improved ability to withstand abrasive wear might be more effective and accurate during spring to avoid high disease pressure and other confounding stresses during summer. ‘Blueray’ and ‘Beacon’ hard fescue, ‘Quatro’ sheep fescue, and ‘Radar’ Chewings were more traffic tolerant than other fine fescue cultivars under low disease pressure. The propensity of fine fescues to bruising under wear needs to be assessed in both summer and autumn.

交通形态和磨损季节影响细羊茅反应

性能优良的羊茅（Festucaspp.) 物种和栽培品种可能因交通形式或磨损模拟季节而异。2012 年启动了两项试验，以评估交通形式（磨料磨损与防滑钉交通）和磨损季节（春季、夏季或秋季）对种植在新泽西州北布伦瑞克的 10 种优质羊茅的影响。用肉眼评估地块的草坪冠层 (FTC) 丰满度和叶片瘀伤。在交通形式试验的最后一个评估期之后评估绿化和土壤物理特性。与非运输控制相比，磨料磨损不断降低细羊茅的 FTC (14-30%)，而在研究结束时，具有夹板交通的地块的 FTC 与非运输控制相似。尽管这两种交通形式都会导致土壤压实，但夹板交通会导致土壤更加压实。与夹板交通相比，磨料磨损提高了细羊茅的选择效率。优质羊茅品种的FTC响应与磨损季节相互作用；因此，在春季筛选具有更好的抗磨蚀能力的细羊茅可能更有效和准确，以避免夏季的高病害压力和其他混杂压力。在低病害压力下，'Blueray' 和'Beacon' 硬羊茅、'Quatro' 绵羊羊茅和'Radar' Chewings 比其他优良的羊茅品种更具交通耐受性。需要在夏季和秋季评估细羊茅在磨损下瘀伤的倾向。在春季筛选具有更好的抗磨蚀能力的细羊茅可能更有效和准确，以避免夏季的高病害压力和其他混杂压力。在低病害压力下，'Blueray' 和'Beacon' 硬羊茅、'Quatro' 绵羊羊茅和'Radar' Chewings 比其他优良的羊茅品种更具交通耐受性。需要在夏季和秋季评估细羊茅在磨损下瘀伤的倾向。在春季筛选具有更好的抗磨蚀能力的细羊茅可能更有效和准确，以避免夏季的高病害压力和其他混杂压力。在低病害压力下，'Blueray' 和'Beacon' 硬羊茅、'Quatro' 绵羊羊茅和'Radar' Chewings 比其他优良的羊茅品种更具交通耐受性。需要在夏季和秋季评估细羊茅在磨损下瘀伤的倾向。
