Fig. 2From: Pathways of extra- and intercellular diffusion of colored substances in the blackened xylem of Diospyros kakiLight micrographs of transverse (a, d), radial (b) and tangential (c, e) sections of whitish regions of samples of D. kaki wood. Black arrowheads indicate colored substances. Black arrows indicate intercellular spaces in the rays where no colored substances were found. White arrowheads indicate blind pits in ray parenchyma cells. AP: axial parenchyma cell; F: wood fiber; RP: ray parenchyma cell; V: vessel element.
