The aim of this study was to evaluate the influence of normal MS culture medium and at half strength of its salts (½ MS), the presence of gibberellic acid (GA3) and citric acid on the in vitro culture of paricá embryonic axes. The embryonic axes were extracted from seeds and inoculated on basic MS and ½ MS culture media, supplemented or not with citric acid (1 g.L-1) and GA3 (3 mg.L-1), constituting 6 treatments and 7 replications. The embryonic axes of paricá may be cultivated on MS medium at half strength of its salts, the addition of citric acid not being necessary, and the presence of 3 mg.L-1 GA3 affected the development of paricá seedling.
