Abstract/Contents:"Bermudagrass (Cynodon dactylon) is a popular sports turf grass in the upper transition zone but low-temperature injury is a common problem in regions where winter temperatures can drop below -12 C. A two-year study was initiated to determine the effects of late-season nitrogen (N) and growth regulator (trinexapac-ethyl) applications on the morphology and cold hardiness of an established Tifway bermudagrass turf. Treatments included either a single application (5 g N per sq. meter) of urea in September or a dual application in September and October. In addition, plots were either sprayed on Sep. 15 with 0.012 ml of trinexapac-ethyl/sq. meter or treated with the same rate of growth regulator on Sep. 15 and Oct. 15. In the winter following treatments, plots were rated for rhizome and stolon density and rhizomes were extracted from the soil and exposed to temperatures of either -2, -4, -6, or -8 C in a controlled freeze chamber. Late-season N extended the growing season of the bermudagrass and stimulated earlier spring green-up. In addition, both a single and dual application of N increased the number of rhizomes. Late-season applications of growth regulator had no effect on the morphology of the turf, but did increase the freeze tolerance of the rhizomes. It was concluded from this study that late-season management can impact the performance and cold tolerance of bermudagrass."
