Table 3.
Hemicellulose composition of four oat hull batches grown under different weather conditions (see Table 1 for description). ND, not detected; NQ, not quantifiable; A/X ratio, arabinose to xylose ratio. All numbers represent triplicate percentages based on dry weight, except for the A/X ratio, which is not a percentage.
