          Abstract

          This work aimed to evaluate the effect of the temperature, osmo-conditioning and pelleting on macela (Egletes viscosa) seeds germination. The experimental design consisted of treatments arranged in a factorial scheme 2x2x2, with two kinds of seeds (with and without pellet), two osmo-conditioning levels (with and without osmo-conditioning) and two temperature exposures (25 and 20-30oC). It was completely randomized with four replicates (50 seeds/replicate). Percentage, velocity index and average time of germination were evaluated. According to the results, the alternate temperature(20-30oC) should be indicated for the germination tests with macela seeds; the osmo-conditioning increases the velocity of germination in alternate temperature exposure; and the presence of pellet does not affect the germination of macela seeds.
