Micropropagation (shoot tip and nodal cuttings culture) was used for the rapid propagation of the non-invasive, decorative, native plants of maiden pink (Dianthus deltoides L.) in order to preserve their genetic diversity. In vitro culture was successfully established on Murashige and Skoog medium (MS) using seeds as the initial material. In the shoot multi- plication phase, the explants were cultured on MS medium supplemented with different concentrations of 6-benzylamin- opurine (BAP) and naphthaleneacetic acid (NAA). Te highest multiplication rate was achieved on a medium containing 0.1 mgL-1 of BAP and 0.1 mgL-1 of NAA. Te rooting was successful on a hormone-free medium (100%), and the highest percentage of microplant acclimatization (97%) was recorded in a 4: 1 mixture of peat and sand.
