Abstract: Maintaining the genotype through asexual propagation is necessary for species with conservation priority (rare and threatened). Silene fabaria subsp. domokina (Caryophyllaceae) is a range-restricted Greek endemic of ornamental value. In autumn, softwood top cuttings (2-3 cm) were cut from mother plants kept inside the greenhouse and their base was immersed for 1 min in IBA (0, 1000, 2000 and 4000 ppm) solutions. Cuttings were placed in multiple disks on a peat: perlite (1:3) substrate on a heated greenhouse mist. The measurements taken were root number/rooted cutting, root length and rooting percentage (%). IBA at 1000 ppm gave the optimum rooting (100%) with 20.75 roots 4.84 cm long (four weeks). The survival percentage of rooted transplanted plants in pots containing a mixture of peat moss, perlite and soil after nine weeks was 100%. This study contributes to the successful ex situ conservation of S. fabaria subsp. domokina and enables its sustainable exploitation.
