Description
The most effective method of propagation as well as the optimal content of plant growth regulators and appropriate supplements to apply were determined for Weeping fig (Ficus benjamina L.) ‘Exotica’, a common woody species grown in indoor conditions. Both, vegetative propagation by cuttings and micropropagation were successfully established in this study. Results of the two-year study on vegetative propagation showed that stem cuttings treated with plant growth regulators containing 0.5% α-naphthalene acetic acid had the greatest percentage of rooting (91.67%). In the study on micropropagation, the effects of cytokinins and activated charcoal on multiplication and rooting were tested. The multiplication faze showed to be the most efficient on MS medium containing 4 mg l-1 BA and 1 mg l-1 IBA. A higher percentage of rooting (50.3%), root length (27.9 mm) and number of roots (5.4) were obtained in plants grown in medium with activated charcoal. Our study showed that the use of adequate plant growth regulators and appropriate supplements (e.g. active charcoal) positively influences the quality and the rapidity of Weeping Fig (Ficus benjamina L.) “Exotica” propagation.
