| The presence of Casparian bands was confirmed by band plasmolysis even in basal parts of old roots, which would not occur with suberin lamella deposition. |
| Cytochemistry and autofluorescence observations were used to detect the presence of lignin and suberin in unfixed tissues. |
| Impregnation of endodermal and hypodermal walls with suberin and lignin should reduce the diameter of interfibrillar spaces. |
| Berberine hemi-sulphate is an acid salt of the alkaloid berberine, which has been used supposedly to confirm the presence of suberin in plant roots. |
| Exodermal suberin lamellae started to develop 30 mm behind the root tip in rice and were fully developed at about 60 mm behind the tip. |
| The hypodermis of all three species has two distinct zones that contain suberin and lignin. |
