Abstract/Contents:"Annual bluegrass is a highly problematic weed in turfgrass systems and causes many issues for managers and producers which in turn drives up management costs and decreasing the aesthetic value of turfgrass systems. Year after year this weed germinates when the environmental conditions are appropriate and begins to disrupt playing surfaces and breaking up various turfgrass. This happens all across the United States, and in some cases isnt limited to the fall through spring season but can become a perennial issue. Understanding the seedbank dynamics and long-term viability of annual bluegrass is vitally important to recommending the best management practices for this weed. To gain better insight into these aspects of seedbank dynamics and seed viability a study was conducted over the past two years in seven locations across the United States along a climatic gradient incorporating multiple USDA plant hardiness zones. Annual bluegrass seed originating from 10 different states along a similar climatic gradient were buried in each of these seven locations at the surface and 5 cm depth. Every six months seed bags containing each population at each depth was retrieved and mailed College Station, Texas where germination and viability assays were conducted to evaluate seed viability at various depths and environmental conditions. Dry storage viability assays were conducted in tandem with each retrieval timing to evaluate seed viability over time in a dry storage environment. There were differences in viability retention based on seed origin where annual bluegrass populations originating from northern locations retained more viability than those from southern locations. Seed viability in dry storage was maintained over the duration. Annual bluegrass seed viability is affected by environment but still remains a opportunistic colonizer and prolific seed producer for its size."
