Estudou-se a dispersão de sementes de cinco árvores-matriz de Platypodium elegans Vog. (Fabaceae) em área de cerradão, na Estação Ecológica do Panga (EEP). As amostragens foram feitas em parcelas de 0,25 m2, posicionadas em linhas partindo da base da matriz em direção aos quatro pontos cardeais (Norte, Sul, Leste e Oeste), marcadas a cada metro. No laboratório, os frutos foram abertos para análise da qualidade das sementes. Foram amostradas 1.131 sementes, das quais 18,4% estavam intactas e 81,6%, danificadas e provavelmente inviáveis para germinação. A dispersão das sementes sofreu influência da topografia do local das matrizes, das respostas fisiológicas e genéticas à pré-dispersão, bem como do possível direcionamento favorável do vento. Dessa forma, a atuação conjunta desses fatores funcionaria como facilitadores relevantes na formação do banco de sementes e moldaria a probabilidade de estabelecimento de novos indivíduos, tanto na área estudada quanto nas fisionomias adjacentes.. It was studied seeds dispersal of five first trees of Platypodium elegans Vog. (Fabaceae), in area of cerradão in the Estação Ecológica do Panga (EEP). The samplings had been made in 0,25 plots of m2, located in lines leaving of the base of the matrix in direction to the four points cardinals (north, south, east and west), marked to each meter. The fruits had been opened for analysis of the quality of the seeds. A total of 1.131 seeds was collected in the sampling area of the five arrays, of which 18,4% they were viable and 81,6% probably impracticable for germination. The dispersion of the seeds suffered influence from the topography of the place of the matrices, of the physiological and genetic answers daily early-dispersion, as well as of the possible favorable aiming of the wind. The joint action of these factors serves as relevant facilitators on the seed bank training as so as the probability of establishment of new individuals both in the studied area and also in adjacent vegetation
