Orchids are among the most sought-after cut and potted plants in the 21st century. Dendrobium antennatum Lindl. is widely used as potted plant or as a cut flower. Due to this aspect, breeders need new propagation methods. In the present study, green antelope orchids were micropropagated using axillary buds at different concentrations of Ferbanat L® medium (0.1, 0.5, 1, and 5%) to assess its positive or negative effects regarding the plant’s growth and development compared to control. The plants’ survival rate was the highest when 5% Ferbanat L® was added to the medium. In the case of the chlorophyll a + b and total carotenoids no significant changes were observed, in the case of the peroxidase activity significant changes were observed by the different treatments. From the study, it can be concluded that control and 5% Ferbanat L® results were almost similar, however the treated plants (5%) recorded a higher survival rate, as well as the healthiest and most size-optimal plants. The results of the present research could positively improve the propagation of the D. antennatum.
