Abstract/Contents:"A two year glasshouse study assessed the heat stress resistance of 137 genotypes from 13 species of cool-season turfgrass to supraoptimal air and soil temperatures indicated by leaf firing percent. All turfs were established from seed, clipped weekly at optimum height, maintained under non-limiting water, and with preventive twice-weekly fungicide treatments. Visual leaf firing ratings were made every two days, air temperature and humidity were recorded continuously, and peak soil and canopy temperatures were measured. There were significant differences in inter- and intraspecie leaf firing, and thus in total percentage of turf canopy fired. There was a significant temperature differential between the soil and canopy temperatures and the air temperature, indicating a heat avoidance mechansim of evapotranspirational cooling aided turf survival of these well-watered turf. Daily air temperature in excess of 43C was required to induce stress in these species. Poa pratensis L., Festuca arundinacea Schreb. and Agrostis gigantea Roth were the most heat resistant turfgrasses, while A. stolonifera L. var. stolonifera, P. trivalis L., and P. compressa were the least."
