Abstract


The propagation with seeds and stem cuttings of Teucrium brevifolium were investigated in order to facilitate the use of the species in floricultural practice and as a medicinal plant. The seeds after they subjected to different types of treatments (dipping in H2SO4 for 15 min or in H2SO4 for 15 min and GA3 1000 mg l-1 for 10 min, 24 or 48h and untreated) cultured for germination in vitro at 5, 10, 15, 20, 25, and 30 °C. The cuttings were planted in a peat/perlite mixture 1:1 v/v in plastic square plug trays in order to study the rooting percentage. Seed germination was very low (2%) at temperatures of 15-25 °C, while chemical treatment with the concentrated H2SO4 for 15 min, increased germination to 8-10% at the same temperatures. Asexual propagation of the species resulted in a 52.5-61.5% rooting percentage, in all seasons except winter. Treatment with IBA 2000 mg l-1 increaseds rooting percentage.
