Abstract
The paper presents results of experiments aimed at in vivo and in vitro propagation of Fabiana imbricata,
an Andean evergreen shrub with impressive ornamental characteristics. Two ornamental types were studied:
with white and with violet flowers. Both in vivo and in vitro propagation methods were successful.
The mean rooting of the cuttings was 87%, and in some cases reaching 100%, but the growing season
influenced considerably the cuttings’ production ability of donor plants. In the case of
micropropagation, application of 0.2 mg l -1 BAP yielded more axillary shoots than higher
BAP concentrations. The best regeneration of adventitious shoots from callus was obtained
on medium with 1 mg l -1 BAP. Protoplast isolation was only possible from callus, because
of the hard needle-shaped leaves of the species. The results proved that there are good
opportunities for further breeding and use of this very promising ornamental in Europe.
Key words: breeding, new ornamental, propagation, Solanaceae
