Digestibility of grassland species and communities in relation to specific leaf weight.

摘要

Studies were made of relationships between digestibility and leaf characteristics of Dactylis glomerata cv. Lude and tall fescue [Festuca arundinacea] cv. Clarine grown near Toulouse, France, pot-grown D. glomerata and F. rubra, and of 4 permanent pastures differing widely in botanical composition at 1250 m alt. in the Central Pyrenees. Leaf digestibility was negatively correlated with specific leaf weight for all species and communities, digestibility of D. glomerata being significantly higher than that of the other 2 species.
