| Abstract/Contents: | "Kentucky bluegrass (Poa pratensis L.) (KBG) is the most popular cool-season turfgrass species due to its density, self-repairing ability, dark green color, and adaptation to sunny landscapes. However, a major constraint of a successful KBG stand is shade. A field study was conducted using controlled shade to determine a daily light integral (DLI) of conventional KBG compared to transgenic ProVista (PV) KBG cultivars. Research was conducted at the Scotts Miracle-Gro research station in Marysville, OH in 2020 and repeated in 2021. Shade levels were controlled using a neutral density, poly-fiber black shade cloth. ProVista Kentucky bluegrasses contain a gene resulting in overexpression of GA2 oxidase causing a dwarf phenotype. Response measures included vertical shoot heights, volumetric soil water content, dark green color index and percent green cover, shoot chlorophyll concentration. Daily Light Integral (DLI) was a main source of quantitative data that was taken every 5 mins over a 24 hour period. Once a growing season, shoot chlorophyll concentration was taken using the dimethyl sulfoxide (DMSO) method. After the first year of data, results showed that ProVista Kentucky bluegrass required a significantly lower amount of light than conventional to retain an acceptable turfgrass quality score. The methods and results of this trial are bridgeable to the greater Agricultural industry to predict and identify plants that have the genetics to thrive in low light abiotic stressed conditions." |
