Resumo: | 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. |

Las semillas se dispusieron en unidades experimentales de 25 semillas y se sometieron a altas y bajas temperaturas y a la ausencia y presencia de luz. Los resultados mostraron la germinación de semillas de A. imperialis solo en presencia de luz, mostrando diferencias en la absorción de agua entre los tratamientos térmicos a lo largo del tiempo y confirmando el comportamiento de imbibición trifásico. A pesar de las diferencias encontradas entre tratamientos, la germinación fue baja, lo que sugiere que el proceso pudo haber sido influenciado por la viabilidad de la semilla y por procesos hídricos puramente físicos. En este sentido, se destaca la importancia de los procedimientos de desinfección y pruebas de vigor, así como la necesidad de futuros estudios de las relaciones hídricas de las semillas en esta especie.
