Interpretive Summary:

Technical Abstract: Seedling mass and emergence force were studied in two greenhouse experiments using 19 half-sib families of ‘Kentucky 31' tall fescue [Lolium arundinaceum (Schreb.) Darbysh.] each of which was produced from genotypes with or without the common toxic endophyte [Neotyphodium coenophialum (Morgan-Jones & Gams) Glenn, Bacon & Hanlin]. There was a large amount of variation across clone-pairs. Endophyte effects on seedling above-ground biomass, tiller number at eight weeks after planting, and emergence through brick grit will be discussed.
