Fig. 5. Ergot alkaloids in the coarse fraction (>1 mm, i.e., coarse sand + remaining leaves) during 32 d of incubation as affected by addition of endophyte-free (E–) and endophyte-infected (E+) tall fescue leaf tissue in soil exposed to long-term history of E– and E+ tall fescue. Curve in each panel represents an exponential decay model fitted to the data for soil plus E+ leaves. Area between dotted lines represents the 95% confidence interval for the combination of soil only and soil plus E– leaves.
