Red radish seeds were irradiated at doses up to 8 kGy using electron beam (e-beam) and gamma ray (γ-ray). Theseed viability and functional properties (carotenoid, chlorophyll, ascorbic acid, and total phenol) of sprouts grown from theseirradiated seeds were evaluated. High germination percentage (≥97%) was observed in seeds irradiated at ≤5kGy, but theyield ratio and sprout length significantly decreased with increased irradiation dose. Irradiation at ≥6kGy resulted in curling ofthe sprout roots. Sprouting enhanced the functional properties of red radish seeds as indicated by the increased carotenoid,chlorophyll, ascorbic acid, and total phenol contents during germination. However, radiation treatment hampered the growthof seeds resulting in underdeveloped sprouts with decreased carotenoid, chlorophyll, ascorbic acid, and total phenol contents.In general, e-beam and γ-ray irradiation of red radish seeds showed similar effects on the seed viability and functionalproperties of sprouts. Postharvest storage reduced the functional quality of sprouts.
