Resumo: The objective of this work was to define the germination substrate of Dalbergia nigra (Vell.) Fr. All. Ex Benth (jacarandá-da-bahia), to evaluate the most appropriate temperature for its seeds germination, and to study its post-seminal morphology, showing normal and abnormal seedlings patterns. Seeds were sowed on filter paper, towel paper and vermiculite, using the constant temperatures of 20, 25, 30 and 35°C as well as alternate temperatures of 20–30°C and 20–35°C. The statistical design was completely randomized (6x3) with 50 seeds sowed in four replications in which the following parameters were analyzed: normal germination (normal seedlings) percentage and speed emergence index. The best results were obtained for temperatures of 25°C and 20–30°C in vermiculite and towel paper substrates. Normal seedlings were classified as faneroepigeal germination type.

Fr. All. Ex Benth (jacarandá-da-bahia), e conhecer a morfologia de seu desenvolvimento pós-seminal e caracterizar as plântulas normais, o tipo de germinação e os padrões de anormalidade. As sementes foram semeadas nos substratos sobre papel, rolo de papel e sobre vermiculita, nas temperaturas constantes de 20, 25, 30 e 35°C e alternadas de 20–30°C e 20–35°C. O delineamento estatístico empregado foi o inteiramente casualizado (6x3), com quatro repetições de 50 sementes. Foram analisados os seguintes parâmetros: porcentagem de germinação normal (plântulas normais) e velocidade de emergência de plântulas. Os melhores resultados foram verificados nas temperaturas de 25°C e 20–30°C, nos substratos sobre vermiculita e rolo de papel. Plântulas normais foram caracterizadas como faneroepígeas em relação ao tipo de germinação.
