  1. Monosaccharide composition of cell walls from spike of 02-5B-318R and SaragollaS wheat plants was determined by HPAEC-PAD. Values are expressed in mol% for each monosaccharide in each fraction. Value represent means ± SD (n = 4). Number in bold indicate statistically significant differences in each monosaccharides between the two genotypes, according to according to Student’s t-test (p < 0.05). ChASS, chelating agent-soluble solids; R = 02-5B-318R; S = SaragollaS.
