Average total pot tiller length (±1 S.E.) across the duration of the experiment, as measured at each of nine measurement intervals (measurements for all treatments were made within a two-day window for each interval).

<p>Asterisks indicate dates for which there was a significant difference between treatment means.

F-value and degree of significance for effects of burn treatment (1x, 2x, unburned control), water regime (dry, wet), and endophyte infection status (E+, E−) and their interactions on biomass measurements and tiller number at the final harvest.

Mean measured growth response variables (±1 S.E.) at the final harvest for tall fescue plants exposed to Wet and Dry water regimes and averaged across burn treatments and endophyte status.

<p>Parameters shown are those for which watering regime had a significant main effect (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0086904#pone-0086904-t001" target="_blank">Table 1</a> above). Letters represent LS Means differences (α = 0.05) for the main water regime effect.</p
