| Abstract/Contents: | "Golf course superintendents are faced with a major challenge when light energy is reduced from tree shade, threatening the underlying vigor of the putting green. Relief from this stress often involves reducing the shade by thinning or removing trees. However, to maintain the natural setting of the course, these remedies are often met with reisistance. A growth chamber study examined growth parameters of FloraDwarf and Tifdwarf bermudagrasses [Cynodon dactylon (L.) Pers. X C. transvaalensis Burtt-Davy] and their response to six light regimes. Light treatments were (a) 12 h at 1540 μmols m-2s-1 + 0 h 63% shade, (b) 8 h 1540 μmols m-2 s-1 + 4 h 63% shade, (c) 6 h 1540 μmols m-2 s-1 + 6 h 63% shade, (d) 4 h 1540 μmols m -2s-1 + 8 h 63% shade, (e) 0 h light + 12 h 30% shade and (f) 0 h light +12 h 63% shade. The shade component was based on a reduction from 1540 μmols m-2 s-1. Results suggest FloraDwarf to have a slight advantage to Tifdwarf in light stressed conditions. At high levels of light stress, FloraDwarf had an 8 to 66% greater net photosynthetic rate suggesting a greater ability to assimilate carbon reserves at lower light levels. While this photosynthetic rate did not result in increased harvestable biomass at these light levels, FloraDwarf exhibits more prostrate growth than Tifdwarf. FloraDwarf had a 12 percent greater cover percentage at the 4 h 1540 μmols m-2 s-1 + 8 h 63% shade treatment compared to Tifdwarf. Furthermore, FloraDwarf displayed lower light compensation points at the high light treatment, also suggesting the ability to survive at lower light levels." |
