| Abstract/Contents: | "A two year study was conducted in Ithaca, NY to evaluate hard red and chewing fescues (Festuca longifolia Thuill, Festuca rubra L.ssp rubra, Festuca rubra L ssp commutata Gaud.) which were observed to inhibit germination and establishment of common annual and perennial weeds in turf. Eighty fescue accessions were evaluated in the field under low to moderate mowing heights for their weed suppressive abilities and suitability for turfgrass. Over two growing seasons, five fescue accessions consistently provided excellent suppression of common turf weeds when established at similar planting densities while other accessions provided moderate to little weed suppression. Laboratory studies were conducted to evaluate potential allelopathic interference of selected fine fescues using agar and sand establishment assays. When suppressive fine fescues were established for 14 days before introduction of weed seeds, curly cress growth was strongly reduced with certain accessions apparently by producing toxic root exudates. Using a capillary mat system to produce large quantities of root biomass, root exudates were collected from fescue accessions of interest. The production of root exudates varied with accession; certain accessions corresponding to those most suppressive in field conditions also produced exudates exhibiting strong inhibition of seed germination. HPLC, TLC and MS techniques are currently being utilized to determine the chemical nature of the bioherbicides in active root exudates." |
