Abstract

Anatomical studies were made of adventitious root formation in the internodes of cuttings from juvenile phase plants of Hedera helix, English ivy. Observations showed that adventitious roots originate in phloem ray parenchyma above the basal cuts within a period of 6-10 days. The actual emergence of the roots is at right angles to the main axis of the stems and the roots appear 10-14 days after the cuttings are made. Fibers are present in groups external and tangential to the phloem strands, but they do not inhibit development of the roots.
