Abstract/Contents:"Athletic field safety is a top concern of field managers and athletic directors across all sports. Increased field usage on surfaces with traffic-sensitive cultivars results in reduced turf cover and increased surface hardness. While most Kentucky bluegrass (KBG) cultivars have strong recuperative potential, many sporting events take place when turfgrass growth and recovery is limited. Therefore, it is critical for the KBG present to exhibit excellent traffic tolerance; however, cultivar differences in ability to withstand athletic field traffic exist. A laboratory study was conducted to determine whether leaf epidermal cell sizes predict differences in KBG cultivar traffic tolerance. Upper epidermal cell size, lower epidermal cell size, and intercellular void space were measured on three traffic-tolerant and three traffic-sensitive KBG cultivars. Transverse sections of leaf tissue were fixed in an acid/alcohol solution and embedded with paraffin prior to sectioning for imaging by light microscopy. Cell size was determined by counting cells per unit area from light microscopy images. Leaf upper and lower epidermal cell size were not significant predictors of traffic tolerance. Differences were measured in intercellular void space at the cultivar level and at the traffic-sensitive versus traffic-tolerant grouping contrast level. Cultivar 'Blue Note' exhibited larger intercellular void space (4177 um2) than all other cultivars (ā‰¤2210 um2). Traffic-tolerant cultivars exhibited 253% larger intercellular void spaces than traffic-sensitive cultivars. Further investigation of these leaf anatomy size theories in relation to athletic traffic tolerance should be conducted on more cultivars and species, including recently released commercially available genotypes."
