Abstract/Contents:"Turfgrass is often affected by foliar shade such as that from trees and shrubs. This type of shade results in reductions in light quantity and the ratio of red to far-red light (R:FR), both of which can decrease turfgrass quality. The conditions produced by foliar shade are quite variable in nature, and little to no information is available on common reductions in light intensity or commonly found R:FR ratios. A considerable amount of research has evaluated the effects of reduced light quantity on turfgrasses using neutral shade cloth and arbitrary reductions in light quantity; however, most of these studies have not addressed changes in R:FR. Experiments have been performed under real-world foliar shade, but a review of the literature indicated that light quantity is not always monitored and the R:FR ratio is rarely reported. The objective of this research was to evaluate changes in light quantity and the R:FR ratio under foliar shaded turfgrasses in St. Paul MN to better understand how we can approach improving tolerance to foliar shade. The results of a two year study indicate that we may be able to better understand foliar shade sites by 1) taking into account fluctuations in light intensity by collecting data every one minute, 2) examining the number of hours at given light intensities rather than only evaluating the daily light integral, and 3) monitoring R:FR in morning, solar noon, and in the evening."
