Description
Perennial ryegrass (Lolium perenne L.) plants, which contained an endophyte (Acremonium lolli), established at higher plant densities than ryegrass plants which seldom contained endophyte. Presence of endophyle did not affect ryegrass planl dry weight or tiller number. Application of phosphatic fertiliser, increased seeding rate, or use of seed which frequently contained endophyte could increase ryegrass tillers/m2• The growth of subterranean clover (Trifolium subterraneum L.), sown with the ryegrass, was reduced when endophyle was presenl in the grass. It is postulaled that the weaker growth of subterranean clover would prejudice its seed production and hence reduce the long-term persistence of clover.
