Abstract/Contents:"Shade imposes a severe limitation on the selection of turfgrass to be used in the Southern Region. Various studies have been conducted to determine the level of shade under which turfgrasses will persist, but few experiments have been designed to determine the parameters which impart shade tolerance to a particular grass. This experiment was conducted in an effort to determine why St. Augustinegrass (Stenotaphrum secundatum ( Walt.) Kuntze) is more tolerant of shaded conditions than is 'Tiflawn' bermudagrass (Cynodon dactylon (L.) Pers.). Special attention was also given to the selection of a reliable indicator which could be used by plant breeders when screening turfgrasses for shade tolerance. Experimental results indicates that although considerable difference exists in the gross anatomy of St. Augustinegrass and 'Tiflawn' bermudagrass, little difference was noted within a species due to shading. Leaf and internode length generally increased under shaded conditions in both grasses, while leaf width increased in St. Augustinegrass and decreased in 'Tiflawn' bermudagrass. An increase in the total chlorophyll content of the grasses substantiated the observation that both grasses had a darker green color under the shade treatment. New photosynthesis and respiration of 'Tiflawn' bermudagrass decreased markedly due to shading, while a slight increase in net photosynthesis and a decrease in respiration was noted for St. Augustinegrass. In both grasses shading caused a reduction in the total available carbohydrate content of the stolons. No characteristic was found that could be used as a consistant indicator for shade tolerance of bermudagrass or St. Augustinegrass."
