Resumen

Justificación: las semillas de pimiento son el punto de partida para la producción agrícola, y su calidad es un factor determinante para el éxito del cultivo. Objetivo: evaluar el efecto de fitorreguladores y microorganismos eficientes autóctonos sobre la calidad fisiológica de semillas de pimiento (Capsicum annuum). Metodología: diseño completamente aleatorizado con arreglo factorial 2 × 4, evaluando dos tiempos de remojo (2 y 4 horas) y cuatro dosis de fitorreguladores (2,5 cc de citoquinina L⁻¹ de agua, 2,5 cc de citoquinina L⁻¹ de agua + 5,0 cc de EMA’s L⁻¹ de agua, 5,0 cc de giberelina L⁻¹ de agua, 5,0 cc de giberelina L⁻¹ de agua + 5,0 cc de EMA’s L⁻¹ de agua). Se utilizaron ocho tratamientos con tres réplicas cada uno. Se evaluó el índice de velocidad y porcentaje de germinación, así como índice de velocidad y porcentaje de emergencia. Resultados: las semillas tratadas con giberelina durante 4 horas fueron las más rápidas en germinar, seguidas por el tratamiento de 2 horas. Ambos tratamientos, lograron mayores porcentajes de germinación. La combinación de giberelina con EMA’s durante 4 horas alcanzó el mayor índice de velocidad de emergencia, seguida por la combinación a 2 horas. En todos los casos, los tratamientos con giberelina mejoraron la emergencia de las semillas. Conclusión: aunque la giberelina fue la más rápida para la germinación, la combinado con EMA’s fue más eficaz para mejorar la emergencia, lo que sugiere que ambos tratamientos tienen efectos complementarios en diferentes fases del proceso de desarrollo de la semilla.
