Abstract/Contents:"Annual bluegrass (Poa annua L.) is an opportunistic species with high phenotypic plasticity and the ability to adapt to many environments. A garden study was conducted in Indiana to determine differences in phenology and survival among ten U.S. populations originating from five different USDA plant hardiness zones. The populations were transplanted in field plots in West Lafayette, IN on 4 Nov. 2020 as individual 3 to 6-tiller seedlings following germination in a greenhouse. Data collected in 2021 included growth rate, biomass production, ground cover, morphology, time of flowering, seed production, and both winter survival and subsequent summer survival of plants. Data analysis revealed that the ten populations separated into three distinct groups. The first group included plants from Northern U.S. (Oregon, Pennsylvania, and Indiana). The plants were characterized by higher growth rates and biomass compared to Southern U.S. ecotypes. These three populations survived the longest during the summer with the Pennsylvania population averaging the highest ground cover of 276 cm2 on 23 July. Plants from warmer climates (Florida, Texas, Tennessee, Alabama, South Carolina, and North Carolina) had poor summer survival. Additionally, the Florida population had the highest winterkill of 68%, followed by Texas at 45%. The New Jersey population was distinct from the other populations. New Jersey plants were characterized by robust above ground biomass and high seed production. The results indicate that the development, reproduction, and survival of different annual bluegrass biotypes are dependent on the climate of origin. Northern biotypes from cool-humid climates persisted longer in summer in Indianas climate than biotypes from warm-humid or transitional-humid climates."
