Abstract/Contents: | "Seed lots and plants of 'Manhattan' perennial ryegrass (Lolium perenne) were examined microscopically for the presence of Lolium endophyte (Epichloe typhina) using an alkali-soak-stain procedure. Commercial seed from early harvests of Manhattan ryegrass (1967-71) contained an average of 45 percent endophyte infection. In contrast, seed harvested in 1982-83 in both North American and Europe averaged only 6 percent infection. Loss of endophyte viability in seed used to establish recent seed production fields would appear to account for this marked reduction in endophyte content. A low-maintenance Manhattan turf seeded in 1972 showed an increase in frequency of endophyte-infected plants from below 45 percent to 91 percent during an 11-year period. This increase indicates that endophyte-infected plants exhibited a selective advantage under the conditions of this test." |
