The Hancornia speciosa Gomes species presents potential for fruit and rubber production. Propagation is difficult primarily due, to a reduced seed germination and occurrence of recalcitrant seeds that stimulate the search of rapid and efficient propagation alternatives. In this context, the aim of this work was to study in vitro seed germination conditions in order to produce explants to be used on in vitro culture. The effect of different culture media, sucrose and GA3 concentrations and three pH levels were evaluated. Seeds were extracted from mature fruits after being harvested and processed. Higher in vitro germination was obtained using WPM and MS/2 media supplemented with 15.0 g L-1, 0.2 mg L-1 GA3 and pH adjusted to 5.8. |
