Cell wall characteristics in leaf and stem of grasses and legumes in mixed swards

摘要

The proportion of grasslands with a cutting-only regime is increasing primarily because the increase in farm size has declined the number of herds grazing.Therefore species as red clover,lucerne and festulolium are becoming more used in grass-leguminous stands.The aim of the experiment was to study the interactions between sward composition and herbage quality and the growth of the individual species in mixtures with one legume and one grass.Cell wall composition varied greatly between plant fractions ( Brink and Fairbrother,1994),and this paper concerns how cell wall composition influence digestibility of organic matter in the different plant fractions.
