In this study we aimed to investigate the action of light and pre-germinative temperature treatments on the imbibition of Alcantarea imperialis seeds. The seeds were arranged in experimental units of 25 seeds without previous disinfestation treatment, subjected to high and low temperatures, and the absence and presence of light. The results revealed the germination of A. imperialis seeds only in the presence of light, showing differences in water absorption between temperature treatments over time and confirming the triphasic imbibition behavior. Despite the differences found between treatments, germination was low, suggesting that the process may have been influenced by seed viability and purely physical water processes. According to this, the importance of disinfestation procedures and vigor tests are emphasized, as well as the need for future studies on the water relations of seeds of this species.
