Fedo	19 ± 5.2^Aa	15 ± 4.6^Ba	20 ± 3.5^Ba	18 ± 2.4^B
Fehu	28 ± 3.2^Aa	38 ± 4.3^Aa	35 ± 5.4^Aa	34 ± 2.6^A

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 ().
