Abstract/Contents:"Among the warm-season turfgrasses, St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] is considered the most shade tolerant and field observations and previous research have found differences among selected cultivars. The objective of this study was to document responses of cultivars to reduced light levels under field conditions. Four cultivars of St. Augustinegrass, 'Seville', 'Floratine' and 'Floralawn' were grown in a split-plot design under full-sunlight and shade levels of 29, 45 and 73% of full-sunlight with shade levels the main plots and cultivars the subplots. Data on leaf area, length, width, stolon number, and rate of ground cover were collected the first year. During the second and third year of the study, data were collected on turf quality, ground cover, and photosynthetic response from shade preconditioning. Cultivars responsed [responded] to reduced light levels with decreased number and length of stolons and percent ground cover while individual leaf area, leaf length, and number of plugs without stolons increased with reduced light levels. A 50% reduction in both length and number of stolons occurred at 57% of full sunlight. All cultivars were equivalent in gross photosynthesis (Pg) when grown at 73% or full sunlight levels. At the lowest light level, Floralawn Pg rate was reduced by 39% compared to Seville. When shading reduces light levels to less than 45% of full sunlight, Floratine and Seville would be the best choices among these St. Augustinegrass cultivars for turf use."
