Summary

Considerable progress has recently been made in understanding adventitious root formation using physiological studies. It is recognized that rooting is a process consisting of distinct phases, each with its own requirements. In this review, the successive phases in the rooting process are described and the possible roles of wounding-related compounds, auxin, ethylene and phenolic compounds during these specific phases are discussed. Recent results are assisting the development of advanced rooting treatments. Molecular studies on rooting are underway and will be essential in revealing the mechanisms underlying adventitious root formation.
