Abstract

A preliminary study of the effect of water stress on alkaloid concentrations in endophyte-infected perennial ryegrass (Lolium perenne) focused on artificial infections with selected endophyte strains (Barker et al., 1993). This paper reports the results of studies of the impact of environmental factors (nitrogen, water, temperature) on the concentration of alkaloids in “Nui” perennial ryegrass naturally infected with Neotyphodium lolii, a more typical component of New Zealand pastoral forage.
