摘要：Enterolobium contortisiliquum (Vell.) Morong a tree commonly known as anglerfish, monkey ear and timbaúva. Due to its wood quality, this tree species is widely used in naval and civil constructions, toys and furniture frames, and can also be used for urban afforestation and restoration of degraded areas. The objective of this work was to standardize the best temperature conditions for conducting the germination tests of E. contortisiliquum seeds under laboratory conditions, considering the fact that the seeds come from coastal tropical Brazil, and to evaluate the desiccation tolerance. The experiments were carried out at the Plant Propagation Laboratory of the Agricultural Engineering and Sciences Campus (CECA) of the Federal University of Alagoas (UFAL), located in the municipality of Rio Largo, Alagoas, Brazil. The design of the experiment was fully randomized, with four repetitions of 25 seeds per treatment. In test I: The newly harvested seeds were subjected to constant temperatures of 5, 10, 15, 20, 25, 30, 35 and 40ºC and alternating temperatures of 20-30ºC, with an eight-hour photoperiod, simulated by four fluorescent lamps 20W daylight type. In trial II: The seeds were divided into two lots. The first was the control (initial moisture content). The second was subjected to slow drying on silica gel. A constant temperature of 30ºC is recommended for the germination and vigor test of E. contortisiliquum seeds. The critical means water content for seeds of this species is below 5%.
