Variations in Cellulosic Ultrastructure of Poplar

Abstract A key property involved in plant recalcitrance is cellulose crystallinity. In an attempt to establish the typical diversity in cellulose ultrastructure for poplar, the variation and distribution of supramolecular and ultrastructural features, including the fraction of crystalline cellulose forms Ia and Ib, para-crystalline cellulose and amorphous cellulose content were characterized.…
