Abstract/Contents:"Hybrid bermudagrass (Cynodon dactylon x transvaalensis Burtt Davvy) is a warm-season turfgrass that can die when exposed to freezing temperatures. Lower temperatures and extended length of exposure to sub-freezing temperatures decrease the chance of bermudagrass surviving through winter dormancy. A study was conducted in Fayetteville, AR in 2023 to determine the effects of soil moisture content and freezing temperature exposure on hybrid bermudagrass survivability. 'Tifway' hybrid bermudagrass plugs were collected and allowed to dry until all plugs had a volumetric water content (VWC) from 0 to 4 cm of less than 12%. Plugs were then separated into four groups based on freezing exposure time: 2, 4, 6, and 8 hours. Twelve plugs from each group were given varying irrigation amounts equal to 12.5 ml, 25 ml, 37.5 ml, 50 ml, 62.5 ml, 75 ml, 87.5 ml, 100 ml, 112 ml, 125 ml, 137.5 ml, or 150 ml to produce a range of soil moisture contents. Plugs were allowed to dry for 24 hours and VWC was again recorded before being placed in a freezer at -9 Ā°C. The plugs were removed from the freezer and then transferred to a greenhouse where they were assessed weekly for visual percent green cover and turfgrass quality (1 = dead turfgrass; 6 = acceptable turfgrass; 9 = excellent turfgrass). Green pixel counts were also measured from light box photos and calculated using Turf Analyzer software for comparison to visual percent green cover. Regression and analysis of variance (ANOVA) (p < 0.05) were conducted to determine soil moisture content and freezing temperature exposure influence on bermudagrass survivability, respectively. There was a positive relationship between soil moisture content and visual percent green cover as well as percent green pixels (p < 0.05). Exposure time did not have a consistent impact on bermudagrass survivability."
