ABSTRACT

The aim of the study was to investigate the optimal factors needed for establishing
an effective protocol for propagation of the cup plant. This species can be applied
in medicine, animal feeding, and as a decorative, apiarian energy-producing and  fitoremediation
plant. Currently, there is no sufficient sowing material in Poland that would
do justice to the present attempts at propagating this species in in vitro growth
cultures. As explants were used cotyledonary and leaf fragments with petioles,
which were placed onto MS media supplemented with BAP in combination with IAA,
ABA, NAA; and onto MS medium fortified with KIN and 2,4 – for callus and
shoot bud initiation. The most efficient callus proliferation reported was on
MS medium incorporated with various concentrations and combinations of auxins
and cytokinins such as BAP (10 mg·dm-3) + NAA (1.0 mg·dm-3), BAP (0.5
mg·dm-3) + 2,4-D (1.0 mg·dm-3) + IAA (1.0 mg·dm-3) + NAA (1.0 mg·dm-3).
The adventitious shoots formed from both the tested explants. It was found that
the highest frequency of explants forming shoots were induced on MS medium containing
BAP (5.0 mg·dm-3) + IAA (0.05 mg·dm-3) and KIN (0.2 mg·dm-3) + IAA (2.0
mg·dm-3), respectively.

Key words: Cup plant, micropropagation, callus, explants, cytokinins, auxins, in vitro.
