Abstract

Analyses of internodes from wheat taken at various times during maturation, and determination of their in vitro dry matter digestibility confirmed that the decrease in digestibility could be attributed both toa progressive loss in cell contents and also to a marked decrease in cell-wall digestibility. The latter was not easily explained by the changes in the proportion of the major wall components (cellulose, arabinoxylan and lignin), but may be explained in terms of the physical andchemical associations between wall polymers. Among these, covalent cross-linking and bridging by hydroxycinnamic acids are important candidates.
