The use of an apical explant source resulted in a
high number of rooted plants. However, when medium was
supplemented with 1.0 mg L-1 IAA, rooting was significantly
higher, indicating that this was the most suitable medium for
short-term production of rooted plantlets. TDZ suppressed the
elongation phase of C. officinalis plantlets; however, in low
concentrations, it provided maximum shooting. The addition
of 0.5 or 0.8 mg L-1 BAP also increased shoot production
without reducing elongation. Rapid micropropagation of C.
officinalis resulted in healthy plants and permitted a continuous
supply of raw material. Rooted plantlets were successfully
adapted to field conditions.
