Propagation of wild-collected Prunus americana Marsh. by rooted cuttings for germplasm conservation in the Southern Appalachians

American plum, Prunus americana Marsh., is a native tree valued for wildlife and wildland restoration. To propagate this tree for germplasm conservation, this study investigated the optimal season of collection and indole-3-butyric acid (IBA) treatment for a viable rooted stem-cutting method. Cuttings were collected from trees in eight locations in May, July, and September, treated with 0-ppm, 1000-ppm, 3000-ppm, or 8000-ppm IBA for five seconds, and held in a mist propagation bed with basal heat for four to six weeks. The results of this study show that (1) rooted cuttings are a viable propagation method for wild-collected American plum, (2) rooting was greatest for May- or July-collected cuttings treated with 3000-ppm or 8000-ppm IBA, (3) cuttings treated with 8000-ppm IBA produced the most roots, (4) May-collected rooted cuttings had greater survival that July or September rooted cuttings, and (5) shoot length was longer for May-collected cuttings treated with 8000-ppm IBA.
