Developmental Stages and Fine Structure of Surface Callus Formed after Debarking of Living Lime Trees (Tilia sp.)

Surface callus formation in lime trees after debarking

Debarking induces surface callus during the vegetative growth period. Using light and transmission electron microscopy, Stobbe et al. (pp. 773-782) show parenchymatous tissue first develops on the wound surface followed by a wound periderm and finally a wound cambium. The wound cambium goes on to form wound xylem and phloem.
