Abstract/Contents:"Blue grama (Boutelous gracilis) was identified as a potential species for no-or low-input areas on golf courses, roadsides, etc., due to its reported ability to germinate under low soil moisture conditions. Previous unpublished work determined that blue grama exhibited superior germination capabilities to warm-season and cool-season turfgrass species at simulated drought stress conditions. The objective of this research was to determine the germination capabilities of blue grama under low moisture conditions. Five commercially available cultivars of blue grama (Alma; Bad River; BirdsEye; Hachita; Lovington) were evaluated for germination capabilities under drought stress conditions utilizing D-mannitol at 0.0; -0.4; -0.8; -1.2; -1.6; -2.0 MPa in sealed petri dishes. Petri dishes were placed under constant fluorescent lighting at room temperature (21Ā°C) for the duration of the study. Total germination and germination rate of all cultivars declined with decreasing osmotic potentials. BirdsEye had the greatest germination of 75% at -2.0 MPa while Lovington had the lowest germination at 20% under the same conditions. As osmotic potentials decreased, days to initial germination and length of the germination window increased. Lovington, at -2.0 MPa, exhibited the longest time to mean first germination date at 6.8 days, but, along with Hachita, exhibited the shortest window from first to last germination date at 12 and 14 days, respectively. Our data validate previous reports that blue grama has germination capacities that could allow for successful establishment under drought conditions. Moreover, these results indicate that blue grama cultivars vary in their performance under drought conditions."
