The Inga vera Will subsp. affinis (DC). T.D. Penn. is fruit native specie from cerrado, commonly for recovering devastated areas. However, its propagation is complicated due to the fact that the seeds are recalcitrant and does not support water loss. The objective of this work was to study Inga vera Willd. subsp. affinis (DC.) T.D. Penn. ex vitro and in vitro germination aspects. For this purpose, different substrates: sand, Plantmax® and sand+ Plantmax®; different salt concentrations: WPM, WPM/2, MS and MS/2, and different GA3 concentrations (0, 5, 10, 17 and 20 µM) were evaluated. The results showed that, in the ex vitro germination, the use of Plantmax® provided the highest germination percentage (82%). Regarding the in vitro germination, highest percentage was observed using WPM/2 (96%). The addition of GA3 was not statistically significant although the concentration of 20 µM promoted an increase in the germination of Inga vera seeds.
