Table 1.

Neutral monosaccharide profile in cell wall fractions of root segments from apex to 5 cm divided into 1-cm segments (S1–S5). Values indicate the percentage of each monosaccharide in each segment (n = 5) ± s.e. Letters indicate a statistical difference among segments; statistically different values are shown in bold (P < 0·05)
