• Crystallinity
• Crystallographic texture
• X-ray diffraction
• Scots pine wood

The standard methods for the crystallinity determination face significant problems with defining the clear boundary between the wood ordered and amorphous areas. Therefore, an alternative procedure describing wood ultrastructural composition was proposed. The new method profits by the application of the texture function and integration of intensities of the crystalline and amorphous X-ray signals. The crystalline volume fraction was defined and applied as a new parameter for the description of ultrastructural organization of wood. The proposed approach was tested for juvenile and mature Scots pine wood (Pinus sylvestris L.). The experimental procedure comprised of measurements of a set of incomplete pole figures, numerical determination of the Orientation Distribution Function, recalculation of a set of complete pole figures, approximation of the total intensities, and calculation of the volume fraction of the crystalline phase.
