Myrciaria floribunda (h. West ex Willd.) O. Berg, known as cambuí, is a fruit shrub of Family Myrtaceae. It’s mainly propagated by seeds and presentes slowness unevenness in the germinative process. For methods of assexual germination, like the in vitro cultive of M. floribunda O. Berg, there are few reports, requiring further studies. This paper aimed to avaliate the in vitro germination of sementes of M. floribunda O. Berg, in diferente storage times, growing media and genotypes. The seeds were taken from ripe fruits of M. floribunda O. Berg, grown in the experimental orchard of CECA/UFAL in Rio Largo – AL. The outline was entirely randomized, in a factorial scheme of 4x2x2, in three storage times (±8ºC of refrigeration for 7 days, 15 days and 30 days) and at room temperature for 24 hours; two growing media (ágar + sacarose and MS) and two genotypes colors of M. floribunda O. Berg (red and Orange), 5 repetitions and 3 seeds per plot. The ágar + sacarose media provided a bigger germination percentual, root and aerial part length, and the MS media contributed for a bigger number of leaves in seedlings of M. floribunda O. Berg. The viability of this fruit shrub seeds in the study was affected by long storage periods at ± 8°C temperature. The genotype type (red of orange) have little or none influency in the evaluated variables.
