| Abstract/Contents: | "Research conducted at the Clemson University greenhouse research complex determined the impact various spectral qualities of light had on morphological and physiological responses of 'Diamond' zoysiagrass (Zoysia matrella (L.) Merr), 'Sea Isle 2000' seashore paspalum (Paspalum vaginatum Swartz.), and 'Tifway' and 'Celebration' bermudagrass (Cynodon dactylon X C. transvaalensis). The study found: 'Diamond' was the most shade tolerant turfgrass, while Celebration and Sea Isle 2000 performed similarly. The least shade tolerant turfgrass was 'Tifway'. Yellow and red shade was least detrimental, while black shade most negatively inhibited parameters measured, followed by blue shade. Under full-sunlight, 'Sea Isle 2000' produced 3.5, 0.8, and 2.9 times greater root biomass and 3.1, 0.6, and 1.8 times greater root length density (RLD) than 'Diamond', 'Celebration', and 'Tifway', respectively. Relative to full sunlight, all shade types reduced root biomass and root length density (RLD) for all warm-season turfgrasses. A high RLD has been correlated with nitrate leaching reductions in previous research. Therefore, nitrogen rates should be reduced in shaded areas because a turfgrass root system is less efficient at nitrate uptake, thus more prone to nitrate leaching. This study implies different types of shade significantly impact the performance of warm-season turfgrasses." |
