Correlation analysis between three wall-polymer features (crystalline index (CrI), xylose/arabinose (Xyl/Ara) and p -coumaryl alcohol/coniferyl alcohol (H / G )) and hexose yield (% cellulose ) released from enzymatic hydrolysis after sodium hydroxide (NaOH) and sulfuric acid (H 2 SO 4 ) pretreatments in wheat ( n  =  10 ). (A) CrI of raw material, (B) Xyl/Ara of non-potassium hydroxide (KOH)-extractable hemicelluloses, (C) H/G of KOH-extractable lignin. *P < 0.05 for correlation coefficient values; **P <0.01for correlation coefficient values.
