Fedo, Festuca dolichophylla; Fehu, Festuca humilior; Cavi, Calamagrostis vicunarum harvested at three times after anthesis (H1, 21 days; H2, 28 days; H3, 35 days). Means with different superscripts in the same row (lowercase letters) or in the same column (uppercase letters) are significantly different ().
