REIS, Iulla Naiff Rabelo de Souza et al. In vitro culture of paricá embryonic axes. Ciênc. agrotec. [online]. 2009, vol.33, n.1, pp. 60-66. ISSN 1413-7054.  http://dx.doi.org/10.1590/S1413-70542009000100008.

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.
