Abstract

The objective of this research was to evaluate the germination of embiruçu seeds harvested in different phases of maturity in different substrates. The evaluated phases were 30, 60 and 80 days after the anthesis (DAA) and the substrates used were paper, sand and vermiculite. The experimental design utilized was the completely randomized (DIC), in a 3 x 3 factorial scheme (three periods of maturity x three substrates), with four replications of 25 seeds. The comparison among the averages of the treatments was made using the Tukey test (α = 0,05). Vermiculite favored higher percentage and velocity of germination of seeds with 60 DAA, while seeds with 80 DAA similarly germinated in the three substrates, although sand had proportionate higher velocity of germination in this phase.
