1. Vegetative propagation of plants via cuttings depends on adventitious root formation. 2. Ethylene slows down primary and adventitious root elongation and formation. 3. This species features very large, petiolated leaves with long adventitious roots . 4. Sometimes it uses adventitious roots to this end. 5. However, high concentrations of auxin inhibit root elongation and instead enhance adventitious root formation. 6. Adventitious roots are uncommon and possibly grow just occasionally when the stems become very long.7. Natural layering typically occurs when a branch touches the ground, whereupon it produces adventitious roots . 8. The ability of plant stems to form adventitious roots is utilised in commercial propagation by cuttings. 9. Successful establishment requires a modest amount of soil moisture during the extension and development of adventitious roots . 10. The Tree Fern has quite adventitious roots , tubercles and hair-like follicles on its trunk.
