Abstract:
Jewel, Carver, and Georgia Jet sweet potatoes were irradiated with ultraviolet radiation (UV). UV irradiation effectively decreased the percentage rot of sweet potatoes during storage. The optimum dose was 4.8 × 104 erg/mm2 for Jewel and Carver, and 3.6 × 104 erg/mm2 for Georgia Jet. UV was effective Botran (2, 6-dichloro-4-nitroaniline) in controlling of Fusarium rot. The effect of UV irradiation on nutrients of Jewel was not significant except that starch content was higher for UV-irradiated roots than for the non-irradiated roots.
