This book was released on 2008 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Creeping bentgrass (Agrostis stoloniferia) and Kentucky bluegrass (Poa Pratensis L.) are two widely-used cool-season grasses grown extensively in northern regions of the United States. Creeping bentgrass is primarily used on golf courses, while Kentucky bluegrass has extensive uses in both home lawns and sports fields. Each of these areas of use are coming under increased scrutiny in regards to water management and conservation. Communities are increasingly putting greater restrictions on both the amount and type of water that can be used for irrigating golf courses, sports fields, and home lawns. The focus of our project was to develop a greater understanding of these grasses' water use, as a way to establish ideal water management practices. The field portion of the project focused on irrigation frequency as applied to three bentgrass species maintained as golf course fairways. Results suggested that reducing frequency and watering one or two times per week, while still replacing 100% of evapotranspiration (ET), produced equivalent, if not improved turf quality, and actually held water deeper in the soil profile, reducing evaporation losses to the atmosphere. In addition to the field portion of the project, experiments were conducted in growth chambers evaluating both creeping bentgrass and Kentucky bluegrass physiological responses to drought and summer stress. Specific findings suggested that exfoliar application of abscisic acid (ABA) or trinexapac-ethyl, a giberrelin inhibitor, significantly improved plant drought tolerance. Further research evaluated genotypic variation between varieties of these species, suggesting that both tolerance and avoidance traits are employed to protect plant physiological function under water deficit.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Water use of low-cut turfgrass at different heights of cut (HOC) or different fertility levels is not known, and information on turfgrass performance during different water deficit conditions is limited. The effects of HOC (3 vs. 5 mm), nitrogen (N) levels prior to drought (0.8, 4.0, 8.0, and 16 g total N m-2 for 60 d), phosphorus (P) level (1.1 g total P m-2 vs. no P), and turfgrass variety ('L93' and 'Penncross' creeping bentgrasses, annual bluegrass, and 'SR7200' velvet bentgrass) under three drought conditions (no drought, periodic drought, and prolonged drought, including a drought recovery phase) on turfgrass growth, net carbon exchange rate (Pn rate), and root parameters were measured through three separate experiments. Real-time water consumption using mini-lysimeter load cell arrays under three drought conditions was also measured. The novel mini-lysimeters were able to detect weight changes of 20.3 cm2 pots containing grass at 1-min intervals, and evapotranspiration (ET) differences between treatments at 1-h intervals. The 5 mm HOC resulted in ~8% more water use than the 3 mm HOC for full cover turfgrass with sufficient irrigation. Turfgrass at 5 mm HOC had higher color ratings, Pn rate, and water use efficiency than turfgrass at 3 mm HOC at the beginning phase of drought. Higher HOC resulted in a faster decrease of hourly ET than lower HOC under drought conditions due to greater water consumption and lower water availability. The 8 g m-2 total N level resulted in better turf performance and more water use than lower N rates. However, 16 g m-2 total N did not improve turf growth from the 8 g m-2 total N level. Increasing N rates improved drought tolerance (measured through Pn rate) during drought and post-drought recovery periods. Turfgrass varieties respond differently to P levels under drought. Low P may improve drought tolerance for 'Penncross' creeping bentgrass, whereas high P may lead to better drought tolerance for 'SR7200' velvet bentgrass. These findings contribute to the understanding of turfgrass under periodic or prolonged drought conditions and could lead to the use of better predictive models for managing water use by turfgrass manager.

This book was released on 2019 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: One aspect of the golf industry is turfgrass management. Annual bluegrass (Poa annua L.) is a golf course turfgrass species, often in a mixed stand with creeping bentgrass (Agrostis stolonifera). Many golf courses in the transition zone and north can be susceptible to ice or freeze injury to golf course putting greens. Annual bluegrass is more susceptible to ice cover damage than creeping bentgrass. In this thesis we aimed to evaluate mechanisms which could alleviate ice cover stress to annual bluegrass through exogeneous applications of chemicals prior to ice cover through fatty acid analysis of annual bluegrass crown tissue. We also intend to examine the role of the plant growth hormone, ethylene, in annual bluegrass and its effects on ice cover survival.Applications of fungicides or plant growth regulators to golf course putting greens are common turfgrass management tools. Trinexapac-ethyl, Civitas, paclobutrazol, and propiconazole are commonly applied to golf course putting greens. Applications of trinexapac-ethyl decreased unsaturated fatty acids while increasing saturated fatty acids ratios in crown tissue of annual bluegrass while Civitas increased unsaturated fatty acids and decreased saturated fatty acids. This was correlated to ice cover recovery with Civitas increasing recovery and trinexapac ethyl decreasing recovery after ice cover. The gaseous hormone ethylene was then examined to determine its role in changes to fatty acid ratios of annual bluegrass under ice cover. Applications of effective ethylene chemicals decreased unsaturated fatty acid ratios while increasing saturated fatty acid ratios.
