| Abstract/Contents: | "Fine fescues (Festuca spp.) are low maintenance grasses that could be more widely used if the traffic tolerance of these species were improved. Numerous studies indicated that grass fiber content including cellulose, hemicellulose and lignin may have significant effects on traffic tolerance. Preliminary experiments on turf plots indicated that fine fescues maintaining a uniform cover under wear was positively associated with total cell wall content (NDF) but negatively associated with lignin content (ADL). The objective of this study was to determine the relationship of tissue fiber content with wear/traffic tolerance of fine fescue genotypes. Tiller-plots consisting of 157 Chewings fescue (F. rubra L. subsp. fallax), 155 hard fescue (F. brevipilia), and 149 strong creeping red fescue (F. rubra L. subsp. rubra) genotypes replicated six times were established in field trials at North Brunswick, NJ and St. Paul, MN. During June and July 2018, wear tolerance was evaluated on three replications in North Brunswick, NJ using the Rutgers Wear Simulator (RWS); traffic tolerance was evaluated on three replications in St. Paul, MN using a custom-built golf cart traffic simulator. Assessment of wear/traffic tolerance was based on a 1-10 scale visual rating that considered elements of turf density and bruising (loss of green color) of leave tissue. Sixty genotypes from each species were selected for leaf tissue fiber content measurement. Verdure samples were collected from three non-worn/non-trafficked replications 2 weeks after wear/traffic was terminated. Fresh and dry biomass of sampled genotypes were measured to determine leaf water content. Dried biomass was ground (1-mm) and will be scanned with a near-infrared (NIR) spectrometer and digested to determine total cell wall content (NDF), lignocellulose content (ADF), and cellulose content (ADL). Results will be presented." |
