Seashore paspalum georgia12/12/2023 ![]() The specific objectives include development of SSRs for future genetic studies, screening germplasm for salt tolerance, documenting genetic diversity, and identifying QTLs associated with high levels of salt tolerance. The overall objective of this research is to uncover and map key genes involved in the salt tolerance mechanism(s) of the salt-tolerant turfgrass seashore paspalum (Paspalum vaginatum Swartz). This research project involves a team of research scientists and is being lead by the efforts of Mr. Breeding and evaluation efforts are now underway with the goal of releasing new cultivars with high levels of resistance to ACCase-inhibiting herbicides. ![]() ![]() Herbicide resistant breeding lines have been developed and confirmed resistant to ACCase inhibiting herbicides in seashore paspalum and in bentgrass. and evaluation of seashore paspalum germplasm. Our breeding program has developed non-genetically modified (non-GM) herbicide resistant turfgrasses by using a tissue culture technique to select for naturally occurring resistant mutant cells. Verdure: That traffic will wear you down University of Georgia researchers tested silicon’s effects on turfgrass wear tolerance and quality. 2Department of Crop and Soil Sciences, University of Georgia, 1109 Experiment Street, Grin, GA 30223, USA Author for correspondence (e-mail: phone: +1-77 fax: +1-770. There are currently no selective herbicides that can effectively be used to manage many grassy weeds in seashore pasaplum. Non-GM Herbicide Resistance System for Turfīermudagrass and other problematic grassy weeds continue to be a major management issue for seashore paspalum. Research emphasis is on turfgrass as affected by. There are significant problems with weeds/insects/diseases I know that the golf courses that have tried it on Jekyll Island, GA are less than impressed. Goals are to explore the potential of using transgenes from other grasses and/or improving the efficiency of existing paspalum genes with potential to reduce the incidence or severity of dollar spot in seashore paspalum. Seashore Paspalum provides an exciting alternative grass of comparable texture and. Parrott’s lab, is leading a research project focused on improving the dollar spot resistance of seashore paspalum. ResearchĪreas include breeding methodology, herbicide resistance systems, genetics of salt tolerance and disease resistance traits, and development of molecular markers for important traits such as salt tolerance. Breeding goals are to develop cultivars for high-stress environments with improved salt tolerance, drought tolerance, disease resistance, and insect resistance. Table 4.Primary emphasis is placed on the development of improved cultivars of seashore paspalum, tall fescue, zoysiagrass, and creeping bentgrass for a range of fine-turf and environmental applications. Single application rates should range from 0.5 to 1 lb of N per 1,000 ft 2 applied during the summer growing season. Recommended Mowing Frequency: Home Lawns: Weekly using a rotary mower Golf and Athletic Turf: Daily to weekly using a rotary or reel mower Putting Greens: Daily using a reel mower.įertilization Requirements: 2 to 4 lbs N per 1,000 ft 2 per year. Recommended Mowing Height: Home Lawns: 1-2 inches (Rotary mower) Golf and Athletic Turf: 0.75 to 1 inch (Reel mower) Putting Greens: ≤ 0.150 inches (Reel mower). Seashore Paspalum (Paspalum vaginatum) Evaluated Under Shade Conditions Abstract. Weaknesses: Cold tolerance and high disease potential Perfect for home lawns, event lawns and golf courses here in Hawaii, SeaStar was developed by turfgrass breeders at the University of Georgia. Strengths: Salinity tolerance, shade tolerance, and traffic tolerance. As a result of its lack of cold tolerance, its use is typically confined to the southern most parts of the country, including south Texas. Relative to bermudagrass, it has higher shade tolerance and less cold tolerance. It is most commonly used in areas where salinity is a concern due to proximity to the coast or poor-quality ground water. Occasionally a third spike-like branch sometimes below the paired branches.ĭescription: Seashore paspalum is a warm-season turfgrass that spreads laterally by rhizomes and stolons and is very similar to bermudagrass in its appearance and performance. Inflorescence: Panicle with 1 to many spike-like terminal, paired branches. Leaf: Scattered hairs may be present on upper and lower surface Growth Habit: Rhizomatous and Stoloniferous Native Seashore Paspalum has more commercial sod use than residential, but if you are experiencing serious salt issues this sod may be perfect for coastal.
