The rate ofgermination and seedling root growth have important implications for competition between specieson a golf green. This research project has shown that P. annua is a very competitive species, due toquicker germination at lower temperatures, especially compared to A. stolonifera and F. rubra sspcommuntata. Root growth of P.annua was also significantly quicker than of the Agrostis speciestested. Seedlings of Agrostis species and F.rubra ssp commutata that germinate in close proximityto P. annua seedlings stand a large chance of being choked out. In order to reduce competition withP.annua, early seeding should be avoided. In this study, no difference in turfgrass establishment wasobserved when seedlings were grown using soil water extracts or soil from an ice-encased green,compared to a control. However, further investigations regarding reestablishment following iceencasement are warrant, and should be investigated on older greens with a higher organic mattercontent. The results from the demonstration trials emphasize the importance of using a sowingtechnique that ensures proper seed – soil contact. This is of particular importance for theestablishment of turfgrass species on golf greens, due to the high risk of desiccation.
