| Abstract/Contents: | "Due to fungicide restrictions, harsh winters and special light/temperature combinations at high latitudes, turfgrass variety testing in USA, UK and central Europe has limited relevance for Scandinavia. Thus, trials comparing 41 varieties of seven turfgrass species/subspecies on USGA-greens at two sites in the northern and two sites in the southern climatic zone of Scandinavia were conducted from 2007 to 2010. Once established, the trials were mowed at 3 mm for bentgrasses (Agrostis stolonifera, Agrostis Canina, and Agrostis capillaris) and 5 mm for chewings fescue (Festuca rubra ssp. commutata), slender creeping red fescue (Festuca rubra ssp. litoralis), perennial ryegrass (Lolium perenne), and rough bluegrass (Poa trivialis). Mean fertilizers rates in the evaluation years were 1.7 kg N/100 m2 to creeping bentgrass and rough bluegrass and 1.0 kg N/100 m2 to the other species. No pesticides were used in the trials. As the trial at Östra Ljungby, Southern Sweden, had to be closed in 2009, species and varieties were ranked based on overall performance (visual merit), winter damage, in-season diseases, and tiller density at Landvik (58° 11'N, 12 m a.s.l.) in the southern climatic zone and at Apelsvoll (61° 42'N, 250 m a.s.l.) and Reykjavik (64° 09'N, 30 m a.s.l.) in the northern climatic zone. On average for varieties within species, red fescue, especially chewings fescue, had significantly less winter damage (both biotic and abiotic damage) than perennial ryegrass and the bentgrasses in both climatic zones. The red fescues also had significantly less in-season diseases (mainly Microdochium patch and Pythium) compared with colonial bnetgrass and velvet bentgrass in the southern climatic zone and in comparison with all bentgrass species in the northerm climatic zone. On average for all sites, velvet bentgrass had higher tiller density, better dormancy color and less height growth, but it also accumulated more thatch than the other species. On average for varieties, the ranking of species based on overall performance was velvet bentgrass > creeping bentgrass > chewings fescue > slender creeping fescue > colonial bentgrass > perennial ryegrass > rough bluegrass in the southern climatic zone and chewings fescue > slender creeping fescue > velvet bentgrass > creeping bentgrass > colonial bentgrass > perennial ryegrass > rough bluegrass > perennial ryegrass in the northern climatic zone. Variety differences within each species at each test site were usually significant, but significant interactions also suggested that different varieties should be preferred in the two climatic zones. In the following table, presented in alphabetical order, varieties indicated in bold have been added to our previously published list of recommended varieties for putting greens in the Nordic countries: [Table]" |
