Abstract/Contents:"Shade stress is among the most problematic issues facing managers of warm-season turfgrasses, and improvement in this trait for commonly-used species would benefit most sectors of the turf industry. A greenhouse study was conducted on four genotypes each of St. Augustinegrass (Stenotaphrum secundatum) and hybrid bermudagrass (Cynodon dactylon ┼ĺ C. transvaalensis) varying in shade tolerance based on prior field trials. The objective of this study was to quantify the light use efficiency of selected warm-season turfgrasses using measurements of photosynthetic parameters. Grasses were established as plugs in 5cm (bermudagrass) or 10cm (St. Augustinegrass) grow tubes constructed from 20cm long PVC pipe. Acclimating period of six weeks was given to the grasses before they were exposed to either supplemental light or shaded using a black poly-woven fabric to reduce photosynthetic photon flux by 60 or 90% of ambient conditions for bermudagrass and St. Augustinegrass, respectively. Parameters such as dark respiration rate, light compensation point, and maximum photosynthetic rate were measured at 8 weeks after treatment. Results from a single run of this experiment will be discussed."
