Abstract/Contents:Presents an ongoing study initiated during 2008 to determine a bermudagrass germplasm that is shade-resistant. Notes that the primary objectives of the study were to "(1) screen bermudagrass germplasm collections and selections for their effectiveness in shaded environments," "(2) determine turfgrass characteristics that may [be] useful for screening future selections for potential shade tolerance," and "(3) create one or two genetic populations by physiological and molecular selections of shade tolerant and susceptible parents for future research." Details methods and materials used during the study, stating that "the bermudagrass selections were collected primarily from China, Africa, Australia, and other nations. Plot size was 61 x 61 cm [centimeters] with a 23 cm border between plots." Reports that "turfgrass visual quality ratings and NDVI [normalized difference vegetative index] indicated significant diversity among selections." Concludes that "shade stress was severe in 2010 and provided adequate stress for selecting resistant grasses and measuring differences in photosynthesis rates." Mentions changes to be implemented during 2011 "to develop a relationship between shade stress and CO2 [carbon dioxide] gas exchange."

USGA Summary Points:In 2010, the shade site received 33% of the solar irradiance received on the sun site. Turfgrass visual quality ratings and NDVI indicated significant diversity among selections. The mean visual turf quality decline between like selections in full sun to shade was 39% and the mean decline in NDVI quality was 24%.
