Progress of the healing callus. Cross sections of the lateral edge 28 days after wounding, in bright-field (A and C) and fluorescence microscopy (B and D), showing the new suberized periderm (A, B, arrows; stained with phlorogucinol-HCl). Close to the ventral part of the healing tissue, several xylem cells appear filled with tannins (C, D, arrow; stained with vanillin-HCl).
