Warm-season grasses are known to be more wear tolerant than cool-season grasses, but in northern Italy the latter are generally preferred for ornamental turfgrasses and athletics fields. The Po River valley, in the North of Italy, is a typical transition zone where species and cultivar selection play a very important role in establishing successful turfgrasses with high stress tolerance, including foot traffic. The aim of this research was to evaluate the traffic tolerance and adaptation of 25 cultivars of three coolseason turfgrass species to transitional growing conditions of Italy. A study was conducted over a two-year period at the experimental farm of Padova University in Legnaro. The species studied were tall fescue (Lolium arundinaceum), kentucky bluegrass (Poa pratensis), and perennial ryegrass (Lolium perenne). Simulated traffic was applied using a Brinkman traffic simulator at a level equivalent to one soccer game per week. Turfgrass quality and density were assessed every week using a 1 to 9 visual scale during traffic treatments each year. Furthermore, turfgrass canopy height was measured weekly for calculating daily vertical growth rate (mm d-1) in spring, summer, and autumn. Trafficked plots exhibited lower quality than nontrafficked, primarily as a result of decline in turf density. The effect of traffic on density was more evident in the second year wherein all species exhibited ratings lower than 5.0. Traffic did not affect turf growth for perennial ryegrass and tall fescue, while a drastic decrease in growth rate in the second year of study was observed for kentucky bluegrass. Perennial ryegrass had lower density than tall fescue and kentucky bluegrass, especially in summer and autumn of the first year when it showed ratings lower than 6.0. Different responses occurred among kentucky bluegrass cultivars, while perennial ryegrass and tall fescue cultivars responded similarly. Results indicated a high quality and environmental adaptability of ‘Rhambler SRP’ tall fescue. Among kentucky bluegrass cultivars, ‘Mystere’ displayed the best wear tolerance with a decrease of density from 5.5 to 4.3 only during the second year. Perennial ryegrass cultivars were similarly affected by traffic, except for ‘Yorktown III’ which showed the lower performance in both traffic and non-traffic conditions reaching a turf density rating lower than 5.0 in both years of study. © ISHS 2016.
