Resumo: | Virola surinamensis is an Amazonian species of the Myristicaceae family, with significant potential for the restoration of degraded areas, in addition to being one of the species currently most explored by the timber industry in the Amazon estuary. However, seed germination and seedling production are hampered by the presence of embryonic dormancy in the species, requiring the use of methods to assist their germination processes. The objective of this study was to evaluate the effect of the application of gibberellic acid (GA3) on seed germination and on the initial biomass production of Virola surinamensis. The design used was completely randomized, with the seeds immersed for 24h in different concentrations of gibberellic acid (0, 500, 600, 700 and 800 ppm) with five repetitions of 25 seeds, using as sand substrate and tanned sawdust (1: 1 v/v). Analysis of variance and regression of the results was performed and the treatment averages were compared by the Tukey test at the level of 5% probability (p <0.05). The 600 ppm dosage was more effective in increasing the emergence percentage (E) by 28.2%, the emergence speed index (IVE) in 0.246, germination (G) in 30.2% and the accumulation total biomass (MST) at 3.704 g / seedlings and, for the days to start the emergency (DIE), the 800 ppm treatment promoted a 27% reduction in the average emergency time. All concentrations of gibberellic acid positively influenced the germination processes and the accumulation of total biomass in the seedlings of Virola surinamensis. |

Sin embargo, la germinación de semillas y la producción de plántulas se ven obstaculizadas por la presencia de latencia embrionaria en la especie, lo que requiere el uso de métodos para ayudar a sus procesos de germinación. El objetivo de este estudio fue evaluar el efecto de la aplicación de ácido giberélico (GA3) sobre la germinación de semillas y sobre la producción inicial de biomasa de Virola surinamensis. El diseño utilizado fue completamente al azar, con las semillas sumergidas durante 24 horas en diferentes concentraciones de ácido giberélico (0, 500, 600, 700 y 800 ppm) con cinco repeticiones de 25 semillas, utilizando como sustrato arena y aserrín curtido (1: 1 v / v). Se realizó análisis de varianza y regresión de los resultados y se compararon los promedios de tratamiento mediante la prueba de Tukey al nivel de 5% de probabilidad (p <0.05). La dosis de 600 ppm fue más efectiva para incrementar el porcentaje de emergencia (E) en 28.2%, el índice de velocidad de emergencia (IVE) en 0.246, la germinación (G) en 30.2% y la acumulación biomasa total (MST) a 3.704 g / plántula y, para los días de inicio de emergencia (DIE), el tratamiento de 800 ppm promovió una reducción del 27% en el tiempo promedio de emergencia. Todas las concentraciones de ácido giberélico influyeron positivamente en los procesos de germinación y acumulación de biomasa total en las plántulas de Virola surinamensis.A Virola surinamensis é uma espécie Amazônica da família Myristicaceae, com expressivo potencial para a restauração de áreas degradadas além de ser uma das espécies atualmente mais exploradas pela indústria madeireira do estuário amazônico. Entretanto, a germinação das sementes e a produção de mudas são dificultadas pela presença da dormência embrionária na espécie, sendo necessária a utilização de métodos para auxiliar os seus processos germinativos. Objetivou-se com este estudo avaliar o efeito da aplicação de ácido giberélico (GA3) na germinação de sementes e na produção de biomassa inicial de Virola surinamensis. O delineamento utilizado foi inteiramente casualizado, sendo as sementes imersas por 24h em diferentes concentrações de ácido giberélico (0, 500, 600, 700 e 800 ppm) com cinco repetições de 25 sementes, utilizando-se como substrato areia e serragem curtida (1:1 v/v). Realizou-se análise de variância e de regressão dos resultados e as médias dos tratamentos foram comparadas pelo teste de Tukey ao nível de 5% de probabilidade (p<0,05). A dosagem de 600 ppm apresentou-se mais eficaz para aumentar a porcentagem de emergência (E) em 28,2%, o índice de velocidade de emergência (IVE) em 0,246, a germinação (G) em 30,2% e o acúmulo de biomassa total (MST) em 3,704 g/plântulas e, para os dias para início da emergência (DIE) o tratamento de 800 ppm promoveu redução no tempo médio de emergência em 27%.
