“…Plants were placed into the chambers described above and allowed to acclimate an additional 5 d at 4.5°C for a total of 35 d. After the acclimation period, the number of live tillers plant -1 was recorded and plant tops were cut to a 2.5-to 3.0-cm residual. The roots were left uncut since tall fescue accumulates root mass throughout the winter and uses those roots for storage of remobilized nutrients from the senesced leaves in the fall and winter (Remley, 2010). After counting and clipping, the chambers were set to 0°C, and this temperature was maintained for 24 h. Then the chambers were programmed to decrease in temperature at approximately 1.5°C h -1 until reaching the fi nal temperature of -12°C.…”

Tall fescue [Festuca arundinacea Schreb. syn. Lolium arundinaceum (Schreb,) Darbysh,] is widely used for hay and pasture in the Eastern regions of the United States, with new types of Mediterranean tali fescue possessing superior growth under cool growing conditions. However, they do not survive Midwestern winters. To date, littie research has examined the role of endophyte infection on the ability of tall fescue to grow under cold conditions or survive freezing conditions. This study's objectives determined the endophyte's roie in tali fescue growth and production of metabolites for nonfreezing conditions. Additionally, the roie of endophyte infection on the ability of plants to survive freezing temperatures was determined. This experiment used five genotypes of tali fescue. Half of the plants from each genotype were endophyte infected (E+), with the remaining genotypes being endophyte free (E-), We report for the first time the effects of endophyte status on proline, simple sugars, and fructan accumulation when plants were grown under cold, nonfreezing temperatures and the survivabiiity at various freezing temperatures, Endophyte removal only affected fructan concentrations at 4,5°C; however, plant genotype affected leaf extension rate, proline, sugars, and fructan concentration. The freezing test found no effect of the endophyte on tiller survival, while plant genotype was significant. These data indicate that endophyte removal has littie influence on the measured traits, and plant genotype is more critical for survival under cold conditions. ).Abbreviations: DM, dry matter; E+, endophyte infected; E-, endophyte free; LER, leaf extension rate; PPFD, photosynthetic photon flux density; RCBD, randomized complete block design.
