  1. Means ± standard deviation; percentage of fiber components (glucan, xylan, AIL and ASL) based on their original amount in unextracted biomass calculated from alcohol-insoluble residue (AIR) amounts (i.e. (% component in AIR/100) × (100 − % extractives)
  2. AIL: acid-insoluble lignin, ASL: acid-soluble lignin, CA: p-coumaric acid, FA: ferulic acid, MLG: mixed linkage β-d-glucan
