Zusammenfassung: | The Vochysia divergens tree species is distributed in Pantanal region in flooded forest and woodsy pastures. Its characteristics allow it to be used as ornamental, apicultural, production of cellulose pulp and also in popular medicine. Considering the importance of studies about such species, the aim of this study was to evaluate seed germination and vigor after various periods of storage (0, 30, 60, 90, 120 and 150 days) in three environments (refrigerator, laboratory, and moist chamber), with seeds collected from Negro Pantanal, Mato Grosso do Sul state. The statistical design was a factorial 3 x 6 (environment x storage time) with four replicates of 50 seeds per treatment (200 per test), germinated in transparent boxes in germination chambers, with photoperiod of twelve hours of white light. The seeds species presented high water content (24.3%) and latter decayed during the storage period, in all environments. The seeds presented a high germination rate (80%) and a short viability period (120 days) and vigor, high (18.4), decayed during the experiment. Keywords: Pantanal; Rio Negro; forest seeds; cambara. A especie arborea Vochysia divergens e comumente encontrada na regiao do Pantanal, ocupando areas de formacao riparia e de pastagens. Suas caracteristicas permitem a utilizacao em ornamentacao, pratica apicola e producao de polpa de celulose, alem de ser utilizada na medicina popular. Levando-se em consideracao a importancia sobre o conhecimento das especies nativas, o objetivo deste trabalho foi avaliar as taxas de germinacao e vigor apos diferentes periodos de armazenamento (0, 30, 60, 90, 120 e 150 dias) em tres tipos de ambiente (refrigerador, laboratorio e camara umida), com sementes coletadas no Pantanal do Negro, Mato Grosso do Sul. O delineamento experimental foi em esquema fatorial 3 x 6 (ambientes x tempos de armazenamento), com quatro repeticoes de 50 sementes por tratamento (200 por teste), colocadas para germinar em caixas transparentes, sob fotoperiodo de doze horas de luz branca em camaras de germinacao. As sementes da especie possuem teor de agua alto (24,3%), que decai no decorrer do periodo de armazenamento para os tres ambientes. Sua taxa de germinacao e elevada (80%), seu periodo de viabilidade curto (120 dias) e seu vigor, alto (18,4), decaindo tambem no decorrer do armazenamento.
