The jaborandi (Pilocarpus microphyllus Stapf.) is a tree belonging to the Rutaceae family and is well known for its intensive use in the pharmaceutical industry through one of its most active principles, the pilocarpine, used to control glaucoma. The purpose of this research is to develop micropropagation protocols. Shoot tips and stem segments used in the micropropagation were removed from the seedlings grown in vitro and cultivated in MS medium with different concentrations and combinations of growth regulators. A treatment with 3% of NaOCl and the lack of GA3 caused a higher percentage of germination and a lower rate of contamination. The apical segment was the most efficient for shoot emission with best average length under different concentrations of BAP and different combinations of zeatin and kinetin.
