| Abstract/Contents: | "Determining daily light integral requirements for various turfgrass systems has been an effective method for quantifying the amount of photosynthetically active radiation necessary to maintain acceptable quality turfgrass in a controlled research setting. However, shaded areas in the landscape often vary in quantity and duration of photosynthetically active radiation available to turfgrasses. The objective of this research is to determine and compare the daily light integral requirements of four warm season turfgrasses in areas of shade at local golf courses and in a controlled research setting to establish an efficient method for determining minimum daily light integral thresholds in the turfgrass landscape. Two zoysiagrass cultivars, 'Meyer' and 'Cavalier', and two bermudagrasses, 'Astro' bermudagrass and common bermudagrass, were evaluated for visual quality and percent turfgrass cover on golf courses in areas of shade and in the research setting under continuous 22, 40, 60, and 90% shade. In areas where shade was suspected to be the cause of turfgrass decline at local golf courses, quantum sensors measuring photosynthetically active radiation were installed along a line transect at different points where turfgrass had no visible turfgrass decline, was visibly declining, and where significant decline had already occurred to determine minimum daily light integral requirements of each cultivar. Quantum sensors were also installed under each shade treatment to establish daily light integral thresholds for each cultivar in the research setting. Data collection is currently in progress and comparison analysis of the results from each setting will be presented at the 2017 CSSA Annual Meeting." |
