초록

Investigating endophyte distribution, naturally occurring in native grasses, is important
for understanding endophyte-grass associations and using the beneficial effects of
endophytes in cultivated plants. The goal of this study was to investigate endophytes
from natural Festuca spp. in Yunnan, Guizhou, and Sichuan Provinces of China, and to
study the compatibility between the endophytes and turf type tall fescue (Festuca
arundinacea) which is widely used for lawn and athletic fields in that region. Of 628
accessions in F. ovina, 421 had endophytes identified in leaf sheath from on-site
microscopic examination. From Festuca spp, three isolates were obtained from the
seeds and ninety isolates were obtained from seedlings established from the collected
seeds.
The isolates from F. ovina and F. stapfii were tentatively identified as Neotyphodium
typhinum and Neotyphodiumstarii, respectively. We tested compatibility of the two fungal species with seven tall fescue cultivars, Little Hero, Sub Boy, Eldorado, Arid
III, Millennium, Crossfire, and Fawn. N. typhinum or N. starii did not infect
‘Fawn’with either seed injection or seed soaking method. The highest infection rate
byboth N. typhinum and N. starii was in ‘Sun Boy’ and ‘Eldorado’. There were
significant interaction effects between tall fescue cultivar and type of endophyte on
infection.
