Main Article Content
Mature Cycas micronesica trees were among the forest trees that were destined to be removed from a 2012 construction site in northern Guam.Â Forty-nine of these trees were cut at the base and transported to nursery conditions to determine if adventitious root development could be stimulated as a means of saving the trees.Â Fungicide and auxin were applied to the base of each stem, and perlite was used as the container medium.Â A nursery maintained by an experienced cycad horticulturist yielded 41% survival, but half of the rooted plants exhibited severe stem dieback.Â A nursery maintained by general plant nursery specialists without cycad experience resulted in 100% mortality.Â If numerous caveats are acknowledged, whole-tree stem cuttings may yield moderate success for saving C. micronesica trees from construction sites when adequate resources are appropriated to support the nursery phase with experienced cycad biologists.Â
