INITIATION AND DEVELOPMENT OF ADVENTITIOUS ROOTS IN STEM CUTTINGS OF HEDERA HELIX: ANATOMICAL STUDIES OF THE MATURE GROWTH PHASE

Adventitious root formation was studied microscopically in stem cuttings of a difficult-to-root plant, the mature growth phase of Hedera helix, English ivy. Roots were found initiating at the end of 2–4 weeks in phloem ray parenchyma of internodes with and without woundwood and in callus near the basal end of cuttings; roots emerged at the end of 3–5 weeks. The fibro-bundle caps were thicker than those found in juvenile stems, but they did not hamper the development of adventitious roots.
