Previous studies in the evaluation of wear tolerance have been conducted using wear simulators. Research to investigate wear tolerance of C₃ turfgrasses under actual playing conditions and their carrying capacity is limited. Three grass tennis courts (replicates) maintained as official size (single) courts were constructed. Eight species and cultivars were randomized within the three courts (blocks): (1) ‘Keeneland’ Kentucky bluegrass (KB, Poa pratensis L.), (2) ‘Rubix’ KB, (3) ‘Villa’ velvet bentgrass (VBG, Agrostis canina L.), (4) ‘Puritan’ colonial bentgrass (CL, Agrostis capillaris L.), (5) ‘007’ creeping bentgrass (CB, Agrostis stolonifera L.), (6) fine fescue (FF, Festuca spp.) mixture, (7) ‘Karma’ perennial ryegrass (PR, Lolium perenne L.), and (8) ‘Wicked’ PR. Injury at the baseline was measured by counting healthy grass on four dates in 2017 and 2019 using an intersect grid. Carrying capacity at the baseline was derived as hours of play to sustain 90, 80, 70, and 60% grass cover. After 6 wk of actual tennis play involving >120 participating players in 2017 and 2019, KB and PR were superior to other C₃ turfgrass for wear tolerance and carrying capacity. These two species exhibited four times the carrying capacity of FF species and nearly 60% more carrying capacity than bentgrass (BG) species. Species of BG afforded higher shoot density and better traction than KB and PR, with VBG exhibiting the best traction, and FF and PR exhibiting the poorest traction. In 2017, greater cell wall content increased wear tolerance and carrying capacity. Velvet bentgrass was as good as KB and PR in overall wear tolerance and carrying capacity under actual match play.

网球用C3草坪草的种间比较：I.实际比赛中的耐磨性和承载力

使用磨损模拟器已经进行了耐磨性评估的先前研究。研究C ₃草坪草在实际比赛条件下的耐磨性及其承载能力的研究受到限制。建造了三个草地网球场（重复场），作为官方规模（单个）场。在这三个法院（区）中将8个物种和品种随机分配：（1）'Keeneland'肯塔基蓝草（KB，Poa pratensis L.），（2）'Rubix'KB，（3）'Villa'天鹅绒草（VBG，Agrostis canina L。），（4）'Puritan'殖民地弯曲草（CL，Agrostis capillaris L。），（5）'007'爬行弯曲草（CB，Agrostis stolonifera L。），（6）细羊茅（FF，Festuca）spp。）混合物，（7）'Karma'多年生黑麦草（PR，Lolium perenne L.）和（8）'Wicked'PR。通过使用相交网格在2017年和2019年的四个日期对健康草进行计数来测量基线的伤害。基线的承载能力是根据维持90％，80％，70％和60％草地覆盖率的游戏时间得出的。在2017年和2019年进行了6周的实际网球比赛，涉及超过120名选手之后，KB和PR均胜过其他C ₃草坪草具有耐磨性和承载能力。这两个物种的承载力是FF物种的4倍，比原生草（BG）物种的承载能力高出近60％。与KB和PR相比，BG种类提供更高的芽密度和更好的牵引力，其中VBG表现出最好的牵引力，而FF和PR表现出最差的牵引力。2017年，更高的细胞壁含量提高了耐磨性和承载能力。在实际比赛中，天鹅绒草的整体耐磨损性和承载能力与KB和PR相同。
