Resumen
Seeds of Astronium fraxinifolium (Anarcadiaceae) were collected in two years, and submitted to tests of seed germination and vigour (first count, aging and electric conductivity), in order to verify the potencial of conservation and if variations in the seed quality presented on association with genetic parameters. Coefficient of heritability in average (ĥm 2) were 0.91 and 0.97 to germination; 0.90 and 0.96 to first count; 0.93 and 0.97 to aging and 0.95 and 0.99 to electric conductivity, for seeds collected in 1997 and 1998, respectively, evidencing a great heritability to all studied characteristics. Genetic variability was influenced more by environmental conditions of blooming and harvest of seeds than storage time.
