| Abstract/Contents: | "Annual bluegrass is one of the most common and troublesome weeds found in turfgrass systems, greatly increasing management costs and decreasing aesthetic value. This species not only occurs during the cool-season, but can also exhibit perennial characteristics, extending growth well into the summer in several environments. Annual bluegrass is a prolific seed producer and establishes a soil seedbank from which it recruits annually. Understanding the seedbank longevity of this species is vital for developing effective management strategies. To this end, a study was conducted between the Fall seasons of 2020 and 2022 in seven locations across the U.S. along a climatic gradient encompassing five USDA plant hardiness zones. Annual bluegrass seed originating from 10 unique populations were placed in polyethylene mesh bags and buried in each of these seven locations at two depths: 0 (surface) and 5 cm. At six-month intervals (for up to 18 months), bags containing the seed of each population were retrieved from each depth and shipped to College Station, TX for conducting germination and viability tests on the extracted seed. Germination and viability assays were conducted in tandem for the seed kept in dry storage for comparison. There were differences in the longevity of seed viability among the seed origins during the 18-month retrieval, where annual bluegrass populations originating from the northern locations appeared to retain greater viability than those from the southern locations. At the 18-month retrieval, the greatest viability (24.8%) was observed with the seed originating from New Jersey (zone 7a), whereas the lowest viability (1.0%) was documented for the seed collected from Alabama (zone 8a). A high degree of seed viability was maintained in the dry storage treatment, indicating the strong influence of field environmental conditions on annual bluegrass seed viability loss. Overall, our findings indicate a relatively short (~one year) seedbank persistence of annual bluegrass, which presents opportunities for targeting soil seedbank through appropriate management practices." |
