| Abstract/Contents: | "The shaded environment poses an irrigation management challenge due to genotypic variation in response to reduced irradiance. Understanding the comparative water use rate of commonly-used turfgrass species in a shaded environment could help promote water conservation and sustainable turfgrass management. The primary objectives of this study were (i) to compare water use rates of selected turfgrasses under two irradiance levels, and (ii) to determine if shade-induced changes in water use rates were related to changes in leaf morphology. An 8-week greenhouse experiment was conducted in fall 2017 using 'Latitude 36' hybrid bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy], 'Falcon IV' tall fescue [Lolium arundinaceum (Schreb.) Darbysh], and 'Meyer' and 'El Toro' zoysiagrass (Zoysia japonica Steud) grown in 15-cm diameter lysimeters. Each cultivar was subjected to two irradiance levels: low light (55% nominal shade fabric) and high light (ambient greenhouse conditions with supplemental artificial lights). Plants were evaluated for normalized difference vegetation index (NDVI), specific leaf area (SLA), leaf elongation rate (LER), leaf angle (LA), chlorophyll content (Chl), and clipping yield (CY) over the study period. The water use rate of each cultivar was obtained gravimetrically between 48-hour periods. Results suggested that there was a significant difference in water use rate among genotypes. Further, the percent reduction in water use due to shade varied among genotypes." |
