Cagaiteira is a native specie of brazilian cerrado with high yield. Because it seeds show high variability, it is yet considered recalcitrant and dormant, the germination in vitro appears as an alternative for specie propagation, in addition to obtain juvenile explant for micropropagation. The present research aimed to evaluate the effect of scarification and ligth on germination in vitro of cagaiteira seeds. Seeds without teguments and intact seeds were inoculated in MS medium and kept in abscence and presence of radiation. Seeds without tegument germinated in the presence or abscence of ligth showed 86.25% and 88.25% germination at 31 and 71 days of inoculation, respectively. After 150 days of inoculation, plantlets from seeds without tegument germinated in the presence and abscence of ligth, showed 10% and 12% of abnormalities, respectively.
