The propagation of the species Tachia grandiflora Maguire & Weaver was studied. Five concentrations of AIB (0, 50, 100, 200 and 400 ppm) were used on 7 cm long cuttings distributed randomly in blocks, replicated 5 times. Each repetition consisted of 5 individual cuttings in washed sand substrate in greenhouse conditions. The hormone was observed to affect root production in cuttings, with highest value (80 %) at 400 ppm. The shortest roots and lowest numbers of roots per cutting were observed where no AIB was applied. In the plant’s natural habitat and soil conditions, the effect of AIB (400 ppm) on the number of live cuttings, sprouting, cutting height (vertical growth), and number of leaves was shown. In conclusion, the propagation of Tachia grandiflora from branch cuttings in a greenhouse and in situ was demonstrated, showing potential as a method to increase the amounts of this relatively rare species.
