Tree Mob™: Using Etiolation to Improve Rooting

The high conservation value of some of the Arnold Arboretum’s accessions call for extraordinary measures to be taken when a valuable accession is in poor health. Propagation by traditional means, for example rooting or grafting cuttings, can preserve these genetic lineages in most cases. Etiolation, a process of shading developing plant stems, developed by Drs. Nina Bassuk of Cornell University and Brian Maynard of University of Rhode Island, can increase the success of rooting cuttings. Christine Ventura will explain this process as it is being trialed on Arnold Arboretum accessions for the first time this year.
