Seed traits are an important measure of the effects of endophytic fungi in Festuca genus. In this study, endophyte-infected (E+) and un-infected (E-) clones of the same tall fescue genotypes were used to investigate the effects of endophyte on the seed production and associated traits. Endophyte infection resulted in 32.8% increase of total seeds by weight, 34.6% seeds per plant, and 30.6% pani...
