Table I.

Composition of Festuca nigrescens (F) and Trifolium alpinum (T) pastures: mean specific contribution (SC, %), mean contribution to defoliation index (CDI, %) during experimental period (P1 and P2). Plant secondary metabolites (PSM) richness from bibliographic data in ordinal scale: − poor to +++ very rich. Letters identify statistical differences of SC and CDI within the same vegetation type depending on the experimental paddock.
