| Abstract/Contents: | "Tolerance to shade is a desired trait for cool-season turfgrasses, but improvement in shade tolerance has been challenging. Shade tolerant turfgrass plants, when subjected to both quantitative and qualitative shade, should exhibit negligible etiolation, decreased chlorosis, and efficient carbohydrate partitioning, while maintaining normal amounts of tillering. However, in the field, shade intensity and the duration of shade exposure can be quite variable, making the selection for shade tolerance difficult. Overall, the fine fescue (Festuca ssp.) turfgrasses are said make up one of the most shade tolerant turfgrasses; however, there has been little investigation into the variability for shade tolerance within and among these species. The objective of this research was to evaluate the use of a greenhouse based approach for selecting for improved shade tolerance among the fine fescues. A total of 45 fine fescue entries consisting of hard (Festuca rubra ssp. brevipila), Chewings (F. rubra ssp. commutata), strong creeping red (F. rubra ssp. rubra), and slender creeping red fescue (F. rubra ssp. litoralis) were germinated and grown under vegetative shade conditions in a greenhouse under a photoselective filter that reduced the red to far-red ratio to 0.68, along with a black shade cloth that reduced light quantity by 30%. Etiolation and tillering were measured throughout the experiment, and samples were analyzed for chlorophyll parameters, specific leaf area, and biomass at the conclusion of the experiment. These data were subjected to principal component analysis (PCA), and results show that most of the variation for improved shade tolerance lies within both Chewings and strong creeping red fescue, with Chewings fescues exhibiting the most improved growth under artificial shade." |
