Resumen


El presente trabajo tiene como objetivo mejorar la cantidad y la calidad de las semillas y/o aceite de semillas mediante el uso de dosis bajas de radiación. Las semillas de sésamo se expusieron a rayos γ- a niveles de 30, 60 y 90 Gy. Los resultados mostraron que las dosis de 30, 60 y 90 Gy activan significativamente la mayor parte de los parámetros de crecimiento y rendimiento (peso de la planta, número de cápsulas, peso de cápsulas/planta y el peso de semillas/planta), siendo 60 Gy la mejor dosis. Con respecto al porcentaje total de aceite producido en los cultivos, se han observado pequeños cambios, pero no se alcanzó el nivel de significación. La cantidad de ácido graso insaturado (18: 1, omega 9) fue 10,5% que aumentó con dosis de 30 Gy seguido de 60 Gy (1,1%). El contenido total de aminoácidos mostró que dosis de 30 Gy registró el valor más alto (350,4 mg·g−1), seguido de 60 Gy (285.6 mg·g−1), en comparación con el valor de control (254,4 mg·g−1). Los valores de fósforo, magnesio, potasio y hierro, que son los principales minerales en las semillas de sésamo incrementaron en las muestras irradiadas.
