For this purpose, propagation experiments with cuttings were performed on four local Ionian endemic species with conservation priority, <em>Stachys ionica </em>Halácsy, <em>Teucrium halascyanum</em>, <em>Thymus holosericeus C</em>elak and <em>Thymus plasonii </em>Adamovic (all Lamiaceae). For propagation, softwood tip cuttings (3-5 cm) were cut at early autumn from mother plants collected from the wild and maintained in open-air mother plantations. For experimentation, the base of cuttings was immersed for 1 min in solutions of four concentrations of IBA (0, 1000, 2000 and 4000 ppm). Cuttings were placed on a peat:perlite (1:3) substrate in the bench of greenhouse heated mist system. Most suitable treatment for <em>T. halascyanum</em> (3 ½ weeks) proved to be 1000 ppm IBA (32.13 roots 1.72 cm long, 100% rooting). Accordingly, 2000 ppm IBA gave 100% rooting for both <em>S. ionica</em> (28.5 roots 1.56 cm long,) (3 weeks) and <em>Th. holosericeus</em> (4.4 roots 1.76 cm long) (7 weeks). <em>T. plasonii</em> cuttings treated with 2000 ppm IBA gave 85.71% optimum rooting with 8.67 roots 1.78 cm long.</p> ER -
