Characterization of lignin from the cell membranes

Lignin macrostructure in the cell membranes of pine wood was investigated e xperimentally by transmission electron microscopy. The obtained data are us ed to reconstruct the lignification dynamics of wood cells. Pseudophase por traits were constructed in the spaces of various dimensions and the Heavisi de correlation functions were calculated. Lignin of the secondary cell wall is demonstrated to have a fractal structure. The lignification is proposed to proceed in the dynamical mode of a strange attractor with a dimension o f 3.7 +/- 0.4.
