| Abstract/Contents: | "Golf courses located in the transition zone often utilize both cool-season and warm-season turfgrass species. Creeping bentgrass putting greens in these regions are surrounded by bermudagrass roughs, often creating problems with bermudagrass encroachment. Currently, no herbicides are labeled for the control of bermudagrass on creeping bentgrass putting greens. Significant differences in shoot density exist between creeping bentgrass cultivars. Turfgrass breeders continue to select for denser creeping bentgrass cultivars in order to alleviate weed pressure and create superior putting surfaces. Therefore, investigation into the ecological interactions between creeping bentgrass and common bermudagrass may provide clues for cultural management. Research was conducted at the Texas Tech Horticultural Greenhouses in Lubbock, TX during the winter of 2010. Mature sod of three creeping bentgrass cultivars ('PennLinks', 'Dominant Plus', and 'SR 1020') were transplanted on December 3, 2010 into 3 L pots filled with a Brownfield Sandy Clay Loam (loamy, mixed, superactive, thermic Arenic Aridic Paleustalfs) and allowed to acclimate for two weeks to encourage rooting prior to trial initiation. A 10.2 cm cup-cutter was used to remove 'Sahara' common bermudagrass cores from a fairway at LakeRidge Country Club. Cores were transplanted into the center of each pot by removing a core of bentgrass and replacing it with a bermudagrass core. Creeping bentgrass pots were mowed three times weekly with handheld grass sheers to a height of 0.32 cm to simulate a golf course putting green. Plants were watered daily with an automated irrigation system calibrated to deliver approximately 5.0 cm of water/week. Fertilizer (16N-10.5P-9.9K) was applied at transplant at a rate of 24.4 kg N/ha and monthly thereafter for the duration of the trial. Greenhouse conditions were maintained at day/night temperatures of 32/26 °C. Natural light was supplemented with artificial light at 400 μmol/m/s photosynthetic photon flux in a 12-h day. The trial was arranged in a randomized complete block design with four replications of treatments. At the conclusion of the trial pots will be placed in a walk-in cooler to initiate bermudagrass dormancy and visually differentiate the two species. Digital photographs will be taken at the conclusion of the trial (June 2011) with a Nikon 10.0 megapixel camera mounted on a portable light box. Pictures will be digitally analyzed using WinCam 2007 software to determine % bermudagrass encroachment. Data will be subjected to analysis of variance (ANOVA) and means will be separated using Fisher's Protected LSD at the 0.05 significance level. Future research will include examining the competitiveness of several creeping bentgrass cultivars (range of shoot densities) with bermudagrass encroachment." |
