| description | Cowpea is the main legume of the Colombian Caribbean. It is cultivated by small producers, who use seeds from their own crops, stored under uncontrolled environmental conditions. The objective of this research was to evaluate the physiological quality of the seeds of five cowpea cultivars stored for 8-10 years. For the electrical conductivity test, six experiments were carried out (0, 4, 8, 12, 16, and 20 hours of imbibition), using a completely randomized design with five replicates of 50 seeds each per treatment. For the germination test in the greenhouse, a randomized complete block design was used with four repetitions of 50 seeds each per treatment. The results indicate that both methods were efficient in identifying reduction of seed viability due to storage effects, with the differential response of cultivars being due to their genetics. The most affected genotypes were L-026 and C-Tierralta, because they showed a greater amount of leachate 107.19±11.81 and 108.87±8.57 µS cm-1 g-1, respectively at 16 h of imbibition, lower percentage of germination and rate of germination speed index. |

El fríjol caupí es la principal leguminosa del Caribe colombiano, cultivada por pequeños productores, quienes usan semillas de sus propios cultivos y almacenadas bajo condiciones ambientales no controladas. El objetivo de esta investigación fue evaluar la calidad fisiológica de la semilla de cinco cultivares de fríjol caupí almacenadas durante 8-10 años. Para la prueba de conductividad eléctrica se hicieron seis experimentos (0, 4, 8, 12, 16 y 20 horas de imbibición), utilizando el diseño completamente aleatorizado con cinco repeticiones de 50 semillas cada una por tratamiento. Para la prueba de germinación convencional en invernadero se utilizó el diseño de bloques completos al azar con cuatro repeticiones de 50 semillas cada una por tratamiento. Los resultados indican que ambos métodos fueron eficientes para identificar la reducción de la viabilidad de la semilla por efectos del almacenamiento, con respuesta diferencial de los cultivares a causa de su genética. Los genotipos más afectados fueron L-026 y C-Tierralta, por acusar una mayor cantidad de lixiviados 107,19±11,81 y 108,87±8,57 µS cm-1 g-1, respectivamente a las 16 h de imbibición, menor porcentaje de germinación e índice de velocidad de germinación.
