Abstract/Contents:"The aim of the project was to find a method to predict the potential growth and winter hardeness [hardiness] of three turf grass species as a function of different light and temperature conditions. Good knowledge of the potential growth is the basis for planning of a sound sustainable maintenance program, both regarding turf grass quality and economical and environmental concerns. A simulation model for grass growth and winter mortality was used to estimate growth curves and winter survival for three different turf grass species (Agrostis stolonifera, Festuca rubra and Poa annua) for different climatic conditions. Four locations in the Nordic countries (Ume^DoA, V^D"ster^DoAs and Lund in Sweden and SÆrheim in Norway) were modeled. The three different places in Sweden represented different light and temperature conditions due to different latitudes. SÆrheim in Norway was selected to represent a more maritime climate. The effect of different climate change scenarios was also tested. Field data from Fullerö GK, Väster^DoAs was sampled during 2007 and 2008 to be used for calibration of the model. The established model could reproduce growth pattern of turfgrass (Agrostis stolonifera) within the range of measurements several years when compared to independent data of grass clippings. However, there are still many uncertainties in the parameterization of the model, and especially with the winter mortality part, because the lack of physiological knowledge of the grass species studied and a lack of observations to test the model against. The results on winter mortality showed very interesting results and identified the complexity between the two opposite processes of hardening and dehardening and the interaction with the climatic conditions during winter to determine the effects on plant mortality. The model showed that although a milder climate reduced the risk for temperatures below the minimum temperatures for grass tolerance at maximum hardening, mild autumns can lead to a less effective hardening so that maximum hardening never is reached. The weaker hardening made the grass more sensitive to low temperatures. A milder climate also decreased the number of days during winter with snow cover. The number of days with snow cover and the depth of snow are very important parameters for the soil surface temperature and thus for the survival of the turf."
