The Effects of Athletic-Field Paint Coloron Net Photosynthesis and Canopy Temperatureof Overseeded Perennial Ryegrass

摘要

ATHLETIC-FIELD MANAGERS routinely paint playing surfaces for proper marking and aesthetics. Commonly, latex, water-based paints specifically manufactured for turfgrass application are diluted at variable ratios with water before application (Reynoldset al., 2012). In the transition zone, bermudagrasses (Cynodon spp.) are most commonly used for sports-field playing surfaces (Christians, 2007). However, to maintain high quality and visually appealing playing surfaces during the dormant season, sportsfields are typically overseeded with perennial ryegrass (Lolium perenne L.); therefore, the majority of play on sports fields occurs on overseeded perennial ryegrass. The goal of this research was to examine the effects of eight athletic-field paint colors on net photosynthesis (NP) and canopy temperature (CT) of overseeded perennial ryegrass.
