| Abstract/Contents: | "The cost, availability, and environmental impact of resources utilized in turfgrass management including water, energy, fertilizers, and pesticides will continue to have a major impact on the turf industry. The intensity of culture required to maintain acceptable turf is dependent on the cultivar in use and on local climatic conditions. Creeping bentgrass provides a premier surface for golf course putting greens. A preference for this species and increasing demands by the public for quality sports turf surfaces have fueled the expansion of bentgrass use throughout the deep South, well beyond this species area of adaptation. The expansion of bentgrasses throughout this environmentally stressful area has out-paced development of stress tolerant bentgrass cultivars. Irrigation and syringing are used on bentgrasses throughout the South to prevent moisture and heat stress. Golf course superintendents pay close attention to soil conditions to ensure adequate soil moisture levels. However, shallow root systems and high evaporative demand frequently expose bentgrass putting greens to physiological drought when atmospheric demand exceeds the turgor maintenance capability of bentgrass. This in turn predisposes bentgrass to heat stress by limiting or even terminating the normal dissipation of thermal energy by evapotranspirational cooling. Physiological Basis for Selection of Bentgrasses with Superior Drought Resistance was initiated to address the relationship of i) water balance in creeping bentgrasses with performance in adverse environments and to ii) assess management systems for the incorporation of diverse bentgrass germplasm into existing bentgrass stands for rapid and efficient improvement of putting green stress resistance and functional quality. Two key individuals were added to this project since 1 July. Mr. David Gilbert, a Master's Degree candidate in the Soil & Crop Sciences Department, joined the project as a Research Assistant. Mr. Gilbert's research responsibilities will emphasize water valance in 20 cultivars and experimental lines of creeping bentgrass. The design phase of his project is complete and data collection will begin during the coming weeks. The second key individual is Mr. Gene Taylor, a Doctor of Philosophy candidate in the Soil & Crop Sciences Department. Mr. Taylor joined the project in late August. His research responsibilities will emphasize the genetic links to water stress resistance mechanisms in an elite population of creeping bentgrass. Mr. Taylor will conduct allied studies to assess the response of creeping bentgrass root development to temperature. A third individual was scheduled to begin a Master's program within this project during August 1994. His responsibilities were to be the assessment of management systems for the incorporation of diverse bentgrass gemplasm into existing bentgrass stands. This individual located three cooperator sites in the Dallas/Fort Worth area to conduct this work. At the last minute, the student quit the program and this phase of the program did not move forward this fall. Cooperating golf courses and superintendents appear willing to move ahead with a spring and fall 1995 program." |
