Adventitious roots may also form from callus tissue at the site of a wound. 8 Secondary Growth in Roots In some woody eudicots the thickening and strengthening of the root system is important in supporting the trunk. Most dicot roots possess at least a small amount of secondary thickening (Fig. 5), with the exception of a few herbaceous species such as Ranunculus (Fig. 3). 8). A notable exception is Dracaena, in which a limited region of secondary tissue is formed111. As in the stem, secondary vascular tissues of the root are produced by a vascular cambium.
The endodermis is a uniseriate cylinder of cortical cells surrounding the central vascular region, adjacent to the pericycle. Endodermal cells are typically characterized by deposition of a band of suberin or lignin in their primary walls, termed a Casparian strip, which forms a barrier against non-selective passage of water through the endodermis. Older endodermal cells often possess thick lamellated secondary walls, in most cases on the inner periclinal wall, so that the Casparian strip is not apparent.
Axial parenchyma cells may be independent of the vessels (apotracheal) or associated with them (paratracheal), and sometimes occur in regular tangential bands. 6 Secondary xylem: Quercus robur (Fagaceae), block of wood at edge of transverse and tangential longitudinal surfaces, showing large early (spring) wood vessels. axial parenchyma cells are often more abundant than fibres, making this type of wood soft and easy to carve. Rays are termed uniseriate if they are one cell wide tangentially, and multiseriate if they are more than one cell wide, viewed in TS and TLS.
