| Abstract/Contents: | "Selecting for turfgrass species that have the ability to out-compete weeds or inhibit the germination and establishment of weeds is a primary component of an integrated weed management strategy. The objective of this experiment was to assess the allelopathic potential of fine fescue taxa and perennial ryegrass (Lolium perenne) against annual bluegrass (Poa annua). Four fine fescue species, Cardinal II creeping red fescue (Festuca. rubra ssp. rubra), Radar Chewings fescue (F. rubra ssp. commutata), Jetty hard fescue (F. brevipila), SeaMist slender creeping red fescue (F. rubra ssp. littoralis), and Wicked perennial ryegrass, were tested for allelopathic effect against annual bluegrass. Two greenhouse tests were performed for estimating the allelopathic effects from either leaf extracts or soil leachates of these five turfgrass species on annual bluegrass germination and seedling development. One additional study was carried out to evaluate emergence and subsequent biomass growth of annual bluegrass seeds sown into strong creeping red fescue, Chewings fescue, hard fescue, and perennial ryegrass mowed at three heights (2.5, 5, 10-cm), as opposed to annual bluegrass seeds sown into trays with bare soil under greenhouse conditions. Despite inhibitory effects on Poa annua germination and seedling growth observed from aqueous leaf extracts and soil leachates of these five cool-season turfgrasses tested, the emergence study had zero emergence three months after Poa annua was sown, suggesting all grass species being equally inhibitory toward Poa annua when turf was dense and competition was present. Therefore, results from our study suggest that, switching to or developing more allelopathic cultivars for more sustainable weed control may be beneficial but that it may not play a significant role in reducing Poa annua invasion in cool-season turf." |
