| Abstract/Contents: | "Shade affects remarkably the durability and development of turf surfaces. Species dependent differences are hereby observed. Objectives of present study were to examine effects of reduced irradiance (65% of ambient sunlight) on photosynthetic capacity, pigment content and growth of commercial cultivars of perennial ryegrass (Lolium perenne L.), red fescue (Festuca rubra L.), smooth-stalked meadowgrass (Poa pratensis L.) and crested hairgrass (Koeleria macrantha (Ledeb.) Schultes). For most cultivars (except 'Enjoy', 'Bartitia' and 'Limousine') leaf elongation was stronger under reduced irradiance compared to full sunlight. Grass coverage decreased under shading. This reduction was highest for L.perenne. Under shade conditions chlorophyll content increased in L. perenne, decreased in P. pratensis and K>macrantha and remained unchanged in red fescue. Carotenoid content decreased in most cultivars, with only 'Olano' and 'Cindy' exhibiting a slight increase. Highest net photosynthesis rates were measured for L. perenne, lowest values for F>rubra spp. trichophylla and K. macrantha. A strong reduction in maximal photosynthetic capacity was observed for P. pratensis grown under reduced irradiance. In contrast, F. rubra spp. rubra reached higher net CO2 gas exchange rates. For the other species no differences in the light response curves (expressed on dry weight basis) were observed between turf plots grown under reduced irradiance and the nonshaded control ones." |
