The results showed for the first time, that lignin dissolved progressively from the secondary walls and the compound middle lamella regions. Samples where the lignin dissolution was limited by transport within the cell walls were markedly heterogeneous and showed large variations in distributions within the morphologically distinct CML and secondary layers. On the other hand, when thin section samples were subjected to pretreatments, the dissolution of lignin was more uniform, and clear distinctions between the morphological layers were observed. CRM distributions of these cell wall components can provide good data for understanding and modeling the physio-chemical processes occurring in the cell walls under different pretreatment conditions.
