Description
Central European varieties of Festuca pratensis Huds. are sometimes infested by the endophytic fungus Acremonium uncinatum. This paper informs about field trials staged on 9 locations for studying biomass and seed yield of different Festuca pratensis varieties, each endophyte-infested (E+) and endophyte-free (E-). In the E+-variants of 2 selected varieties, which were tested in 17 field experiments for field emergence, the number of emerged plants per m2 was significantly increased in 8 cases, preferably on the same location. Analyses of the biomass yield furnished better results in most E+- variants, albeit seldom on a significant level. However, the average values of 10 trials revealed a significant increase of the annual total yield of the E+-variants in 2 varieties. The E+-variants turned out to be also superior in seed performance as proven by the mean values of 10 experiments. The difference to the E--variants was significant in 3 varieties. The symbiotic effects on biomass and seed yield formation caused in Festuca pratensis by the endophytic fungus Acremonium uncinatum may vary depending on the variety.
