| Abstract/Contents: | "The experiment consists of 12 bermudagrass ecotypes of cultivars, each planted in replicated blocks on USGA or native soil putting greens. The objective of the research was to evaluate these bermudagrasses to determine their suitability as putting green grasses in the southeastern United States. Beginning in June, 1996 mowing heights of 1/8 and 3/16 inch were superimposed over the grasses. Grasses were mowed 6 out of 7 days, with grasses receiving the 1/8-inch mowing height treatment often double-mowed to prevent scalping and poor turf quality. Data collection included: 1) evaluations of mole cricket damage (no significant difference due to grass type found, 2) quality ratings, 3) stimpmeter readings, 4) overseed quality ratings, 5) seedhead production counts, and, 6) spring greenup ratings. An additional study was initiated which evaluated ecotype/cultivar response to herbicide application. Preliminary evidence in this study indicates differences in ecotype/cultivar response to various herbicides. Average stimpmeter readings for the grasses were greater at 1/8 inch mowing height than at 3/16 inch mowing height. Average stimp distances at the 1/8 inch height were 6.6 on June 28 and 8.2 feet on Sept. 19, and average distance at the 3/16 inch height were 6.4 on June 28 and 7.3 feet on Sept. 19. Stimpmeter readings were always higher on the USGA green when compared to those obtained on the native soil green. Grasses with high quality turf that had best stimpmeter readings were TW72 and the ecotype Lakewood, a selection from the Lakewood C.C. in New Orleans. The ecotype from the Mobile #10 green of the Mobile C.C. (AL.) always had the fastest spring greenup, but this grass also exhibited undesirable traits of seedhead production and poor turf quality later in the season. None of the other C. dactylon x C. transvaalensis hybrids demonstrated superior ability to green up in the spring. In later quality ratings the grasses TW72, Mobile #9, T596, Texas and the Industry Check all exhibited high turf quality ratings. The ecotype from the #9 green of the Mobile Country Club and the cultivar TW72 both performed well at the 1/8-inch mowing height. These two grasses did not produce seedheads, as did several of the other grasses (Mobile #10, Lakewood, Tifgreen, Tifdwarf). Variants of Tifdwarf showed differences in phenotypic behavior, and some of these ecotypes (Mobile #9) show promise as putting green grasses. The cultivar TW72 performed well in most tests, and tolerates a 1/8 inch mowing height very well. This mowing height was very stressful to many of the grasses, especially Tifgreen." |
