UV-C exposure has become a crucial risk for living organisms due to its widespread use in sterilization. In this study, the mitigating potential of lycopene was investigated against UV-C-mediated toxicity in Allium cepa L. roots. Allium bulbs were separated into six groups which treated with tap water, 215 mg/L lycopene, 430 mg/L lycopene, 254-nm UV radiation, 215 mg/L lycopene + 254-nm UV radiation, and 430 mg/L lycopene + 254-nm UV radiation. Germination percentage, root length, weight gain, mitotic index, micronucleus frequency, and other chromosomal aberrations as well as meristematic cell damages were investigated in all groups. Malondialdehyde level and the activities of superoxide dismutase and catalase enzymes were also analyzed to understand the severity of oxidative stress. UV-C radiation was revealed to negatively affect all parameters investigated, while the mitigating activities of lycopene against UV-C-mediated toxicity were dose-dependent. Therefore, the study evidently demonstrated the promising potential of lycopene in the protection against the detrimental effects of UV-C exposure in A. cepa.
紫外线-C 辐射因其在消毒方面的广泛应用，已成为生物的一个重要危险因素。本研究调查了番茄红素对洋葱根尖中紫外线-C 介导的毒性的缓解潜力。将洋葱鳞茎分为六组，分别用自来水、215mg/L 番茄红素、430mg/L 番茄红素、254nm 紫外线辐射、215mg/L 番茄红素+254nm 紫外线辐射和 430mg/L 番茄红素+254nm 紫外线辐射处理。在所有组中都研究了发芽百分比、根长、增重、有丝分裂指数、微核频率和其他染色体畸变以及分生细胞损伤。还分析了丙二醛水平以及超氧化物歧化酶和过氧化氢酶的活性，以了解氧化应激的严重程度。紫外线-C 辐射对所有研究的参数都有负面影响，而番茄红素对紫外线-C 介导的毒性的缓解作用则是剂量依赖性的。因此，本研究明显证明了番茄红素在保护洋葱免受紫外线-C 暴露的有害影响方面具有广阔的应用前景。
