Conteúdo: 	A study dealing with in vitro cultivation of the umbu tree [Spondias tuberosa (Arr.) Cam], a Brazilian native xilophyta fruit tree was carried out to develop an appropriate micropropagation method. Nodal segments from one-year old seedlings were collected, disinfected superficially and culture on MS (1962) basal medium supplemented with a regime of BAP (6-benzylamino-purine) and IBA (indole-butyric-acid). After one-month cultivation period, the in vitro response was evaluated. the best combination produced 2.2 axillary shoots/nodal segment on semi-solid cujlture medium contnaining 0.1 mg/liter BAP. It seemed thar IBA and high concentration of BAP inhibited the vegetative growth. Vitrification, callusing and polyphenol accumulation were also detected in certain concentration of the growth regulators.
