The changes in microstructural parameters in varieties of wood flour and their native cellulose have been studied using wide angle X-ray scattering (WAXS) method. The crystal imperfection parameters like crystal size < N >, lattice strain (g) and enthalpy (α*) have been determined by profile analysis using Fourier method of Warren. These results were cross checked with the one obtained by matching the stimulated intensity profile obtained from one dimensional Hosemann’s Paracrystalline model. In all this computation we have used (110) and (200) reflection observed in these varieties of wood flour and their native cellulose. We have also computed volume weighted and surface weighted crystal size and compared in these parameters
