Abstract/Contents:"Bermudagrass (Cynodon dactylon)is one of the most frequently-used turfgrasses for golf, sport, and recreational turf throughout tropical, subtropical, and transition zone regions of the world. Recently, a number of seeded bermudagrass cultivars have been released into the turfgrass market and are quickly becoming a popular option for turfgrass managers. A major limitation with these seeded bermudagrasses is poor or slow germination. This can lead to weed-infestation, which can ultimately result in a weak turfgrass stand. One possible means to overcome slow germination is the use of a pre-germination treatment such as osmopriming. The following study was designed to investigate the effects of two osmotic priming agents, polyethylene glycol (PEG) and potassium nitrate (KNO3) on the germination and establishment of a seeded bermudagrass. The cultivar, Jackpot, was exposed to seven different osmotic potential treatments within each solution, ranging from -0.20 to -0.5 MPa. Establishment after a 48 h exposure to these treatments was monitored for 6 weeks. Throughout the experiment, no conclusive evidence was obtained that priming of bermudagrass seed with varying osmotic solutions of PEG (avg. mol. wt. 10000) or KNO3 was an effective means to promote faster germination and establishment. No statistical difference could be detected between KNO3 actually provided inferior results to the control. Further research is needed to determine if other priming methods would be more effective to enhance bermudagrass germination."
