| Abstract/Contents: | "Epichloë spp. are endophytic fungal symbionts present in many turfgrass species (1).It is well established that endophyte (Epichloë coenophiala)-infected (E+) tall fescue (Festuca arundinacea) shows better drought tolerance and recovery than endophyte-free (E-) plants (2, 3). Studies about effects of endophytes on heat stress response of turfgrass are lacking. Strong creeping red fescue (Festuca rubra L. ssp. rubra) is a perennial fine fescue and an important turfgrass in temperate regions. Strong creeping red fescue is often naturally infected with E. festucae, and infection provides benefits to the host, such as insect and pathogen tolerance (4). However, studies on the effects of endophytes on drought stress in fine fescue are lacking. The objective of this study was to determine whether E. festucae has effects on strong creeping red fescue under heat stress, drought stress, and both stresses combined. We compared endophyte-free and endophyte-infected fine fescue(5) and found that there were no significant differences between them under heat stress, drought stress, or the combination of both. The endophytes did not improve abiotic stress resistance of the host. All plants with or without endophytes could recover from the stress. The combination of heat and drought stress impacted plants the most. Separately, fine fescue is more sensitive to drought stress than to heat stress, based on turf quality, chlorophyll content, electrolyte leakage, relative water content and MDA content. Under well-watered condition, the plants were tolerant to heat stress at 35°C. We could expect that higher temperature might impact plants." |
