| description | The objective of the study was to evaluate the morphometry, viability and germination of B. hispida seeds, at the Universidad de Córdoba, Colombia. Eight biometric characteristics were measured in a sample of seeds taken at random from a balanced compound originating from 50 fruits. The external and internal morphological description was made on a sample of 10 seeds. Seed viability was estimated by the tetrazolium test, using the combination of two staining times (2 and 3 hours) and three concentrations of (0.5, 1.0 and 1.5%), under a design completely randomized, with six treatments and four repetitions of 50 seeds. The germination test (PRUGER) was performed in a mesh house with four repetitions of 50 seeds to estimate eight physiological parameters of germination. The morpho-metric characteristics of thickness, length and width of seeds showed reduced phenotypic variation, compared with the weight, density and volume of a seed, with variation coefficients greater than 11.7%. The seed, ovoid and flattened, presents an embryo with its cotyledons wrapped in a protective membrane. The viability, determined with tetrazolium, was 89.5-96.5%, while the PRUGER was 100%, with no statistical differences between them (P≥0.05). The combination of 0.5% tetrazolium with 2 hours is sufficient to determine the viability of the seed. Germination elapsed from 6 to 19 days after sowing, with a germination speed index of 0.22, average daily germination of 5.26%, peak value of 5.33 and germination value of 28. |

El objetivo del estudio fue evaluar la morfometría, viabilidad y germinación de semillas de B. hispida, en la Universidad de Córdoba, Colombia. Se midieron ocho características biométricas en una muestra de semillas tomadas al azar de un compuesto balanceado originado de 50 frutos. La descripción morfológica externa e interna se hizo en una muestra de 10 semillas. La viabilidad de semillas se estimó mediante la prueba de tetrazolio, usando la combinación de dos tiempos de tinción (2 y 3 horas) y tres concentraciones de (0,5; 1,0 y 1,5%), bajo un diseño completamente al azar, con seis tratamientos y cuatro repeticiones de 50 semillas. La prueba de germinación (PRUGER) se realizó en casa malla con cuatro repeticiones de 50 semillas para estimar ocho parámetros fisiológicos de germinación. Las características morfo-métricas grosor, longitud y ancho de semillas mostraron reducida variación fenotípica, en comparación con el peso, densidad y volumen de una semilla, con coeficientes de variación mayores que 11,7%. La semilla, ovoide y aplanada, presenta un embrión con sus cotiledones envueltos en una membrana protectora. La viabilidad, determinada con tetrazolio, fue de 89,5-96,5%, mientras que la PRUGER fue de 100%, sin diferencias estadísticas entre ellas (P≥0,05). La combinación de 0,5% de tetrazolio con 2 horas, son suficientes para determinar la viabilidad de semilla. La germinación transcurrió desde los 6 hasta los 19 días después de la siembra, con índice de velocidad germinativa de 0,22, germinación diaria media de 5,26%, valor pico de 5,33 y valor germinativo de 28.
