  1. *Carbohydrates and lignin analysis completed after extraction with 1% NaOH and subsequently the values are expressed as g per 100 g of original material.
  2. **Values in the bracket represent the deviations of three replicate analysis.
  3. ***Ash values reported are from biomass samples prior to extraction.
