Abstract/Contents:"Annual bluegrass (Poa annua L.) is often considered a serious weed problem for fine-sports turf. However, the species exhibits a wide range of variability in traits like color, shoot density, and life history. As such, there are annual bluegrasses that exist as long-lived perennials with extremely high shoot density [P. annua L. f. reptans (Hausskn.) T. Koyama]. The evolution of these high shoot density perennial-types begins when golf greens planted to creeping bentgrass become infested with the weedy annual types. Because of annual bluegrass's ability to flower and set seed under close mowing heights, each new generation becomes increasingly adapted by investing more of their photosynthetic energy into vegetative growth and less into seed production. Eventually, over decades, the annual bluegrasses that exist on golf greens [will] have a perennial life history with stoloniferous-like shoots, a short-stature, and an enormously high shoot density. These perennial forms of annual bluegrass are an important and valuable turfgrass for the golf industry in various regions worldwide. Because such greenstype annual bluegrasses evolve on-site and cannot survive in environments other than golf greens, they are for all intent [intents] and purposes considered cultivars. Therefore, prospects for developing improved cultivars are extremely good."
