Abstract/Contents: | The effects of different shading intensities (50% and 70% of the photosynthetically active light) on the development of selected turfgrass species and varieties were examined in two vessel experiments. Experiment 1 served to clarify the shade effects under a high mowing height (30mm) on 18 varieties of the species Lolium perenne, Poa pratensis, Poa trivialis, Poa nemoralis, Festuca rubra, and Festuca arundinacea. Experiment 2 investigated the shade effects under a low mowing height (10mm) of 12 varieties of the species Agrostis stolonifera, Agrostis capillaris, Poa supina, and Festuca rubra. The following parameters were assessed during the time period from July 1998 to August 1999 (with the exception of the dormancy period): number of shoots, leaf area index, clipping weight, and degree of cover. The results to date can be summarized as follows: Light reduction caused no delay in germination or loss of seedlings. A negative shade effect was observed only after the beginning of tillering. As shade intensity increased, shoot quantity, leaf area index, clipping weight, and degree of cover all decreased considerably. To assess the shade tolerance, the results of the second vegetation period are also important. Variety-related differences were obvious in Poa pratensis, Poa trivialis (70% shade), Agrostis capillaris and Festuca rubra com. (50% shade). At the 30mm mowing height, Festuca arundinacea proved to be the most shade tolerant turfgrass, whereas Poa supina proved to be the most shade tolerant at the 10mm mowing height. |
