“…These results are consistent with previous research in warm-season turfgrass species where transpiration rates increase with air temperature Green et al, 1991). Previously reported photosynthetic reductions, combined with decreased transpiration and heat stress all contribute to commonly observed declines in turfgrass health and performance as a result of athletic field paint applications.…”

A thletic field paints have increasingly become an integral part of sporting events worldwide with an ever-increasing desire to produce bright, distinct, and often-intricate logos and designs. While these products are specifically designed and labeled for use on athletic turf, repeated applications commonly result in declines in turfgrass quality, density, and performance. The underlying basis for this decline has been linked to reductions in photosynthetically active radiation (PAR) reaching the leaf surface due to absorption by paint pigments and is often color dependent (Reynolds et al., 2012(Reynolds et al., , 2013. However, Reynolds et al. (2013) also reported that the interception of PAR by paint pigments is likely not the only factor implicated in reductions of turfgrass quality in painted turfgrass canopies. For example, in that study white paint absorbed 0.0% of PAR yet still produced total canopy photosynthesis (TCP) rates in 'Tifway' hybrid bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] of only 78 and 83% of the nonpainted control in two separate experiments. Consequently, it is likely that other detrimental effects resulting from athletic field paint applications are contributing to turfgrass decline, in addition to the effects of shading.ABSTRACT Athletic field paints have varying impacts on turfgrass health that have been linked to their ability to alter photosynthetically active radiation and photosynthesis on the basis of color. It was further hypothesized they may also alter transpiration and canopy temperature by disrupting gas exchange at the leaf surface. Growth chamber experiments evaluated the effects of air temperature and six colors of paint on daily water loss and canopy temperature in 'Tifway' bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy]. Daily water loss and canopy temperature were measured every 24 h using gravimetric techniques and an infrared digital thermometer, while lab experiments examined the thickness of white and black paint on the leaf surface. In nonpainted bermudagrass canopies, daily water loss increased (P £ 0.0001) with canopy temperature from 29 to 36°C, while in painted bermudagrass canopies it decreased (P £ 0.0001) as canopy temperature increased from 29 to 40°C. Yellow and white paint impacted transpiration and canopy temperature the least, while black and blue caused the greatest reductions in transpiration and highest increases in canopy temperature. Cross-sections of painted Tifway indicate that paint may limit evaporative cooling by clogging stomata. Increased absorption of radiant energy by paint coupled with limited evaporative cooling result in increased heat stress and decreased turfgrass performance in painted canopies. W.C.

“…However, shoot density or leaf orientation were not correlated with ET in either bermudagrass (Beard et al, 1992) or zoysiagrass ( Zoysia japonica Steud.) (Green et al, 1991). In the present study, these various morphological characteristics were not quantitatively evaluated.…”

This study was designed to determine the effects of deficit irrigation on water use traits of colonial (Agrostis capillaris L.), creeping (A stolonifera L.), and velvet (A canina L.) bentgrasses and to compare their water use. Field experiments were conducted from July to November in 2002 and 2003. Plots were irrigated at four levels of irrigation based on the percentage of actual evapotranspiration (ETa): 100, 80, 60, and 40% ETa replacement. The influence of deficit irrigation on water use was evaluated by measuring soil water depletion (SWD) and water use efficiency (WUE). The WUE was quantified by the ratio of canopy net photosynthetic rate to transpiration rate and carbon isotope discrimination (CID). Evapotranspiration (ET) rates were compared among the three species under nonlimiting moisture conditions (100% ETa). Our results demonstrated that water use characteristics varied with species, irrigation regime, and climatic conditions. Irrigating at either 60 or 80% ETa had no significant effects on WUE compared with 100% ETa irrigation; however, plots irrigated at 60% ETa exhibited higher SWD compared with plots at 80 and 100% ETa Velvet bentgrass exhibited lower SWD, higher WUE, and lower CID compared with colonial bentgrass during the summer treatment period, and creeping bentgrass exhibited intermediate water use characteristics among the three species. These results suggest that irrigating bentgrass species at 60 to 80% ETa could be practiced to increase WUE during summer and 40% ETa during fall months under the conditions of this study.

“…Beard et al (6) reported variations in leaf extension rates among bermudagrass genotypes, and concluded that this variation would require adjustment of mowing frequency between cultivars. Although some reports (6,13,14) document differences in leaf extension rates of species or cultivars, other work (21) shows little difference among species or cultivars. Kim and Beard (21) investigated the vertical leaf extension rate of ‘Arizona Common’ bermudagrass, Tifway bermudagrass, and Meyer zoysiagrass in the greenhouse and reported no differences among these cultivars.…”

Bermudagrass (Cynodon spp. Rich.) and zoysiagrass (Zoysia spp. Willd.) are two of the most commonly used turfgrass species on golf course fairways and tees in the southern United States. However, there are few reports directly comparing commonly used cultivars of bermudagrass to commonly used cultivars of zoysiagrass. The objectives of this research were to quantify the clipping yield, percent ball exposed (ball lie), and to identify the scalping tendency for five bermudagrass and seven zoysiagrass cultivars grown in Fayetteville, AR. The cultivars generally producing the lowest clipping yields were ‘Patriot’ bermudagrass and ‘Meyer’ zoysiagrass, while ‘Tifway’ bermudagrass and ‘Palisades’ zoysiagrass generally had the highest clipping yields. On most collection dates, Cynodon spp. yielded more clippings than Zoysia spp. Patriot bermudagrass had the highest scalping tendency across the two years of this study. The cultivars Patriot, ‘Riviera,’ ‘Tifsport,’ and Tifway bermudagrass as well as Meyer and Diamond zoysiagrass had the best ball lie in unmown (five days after mowing) conditions, while Palisades zoysiagrass had the poorest ball lie in unmown conditions. Ball lie was similar for all cultivars immediately following mowing. These studies identified cultivars of bermudagrass and zoysiagrass that have improved clipping yields, scalping tendencies, and golf ball lie.
