• One of the most drastic diseases causing economic losses in sunflower crops is fusarium root rot caused by Fusarium solani. Plant extracts and ionizing radiation provide alternative environmentally safe control agents that have a significant role in controlling and overcoming this fungal plant pathogen.
• In the present study, the effect of different concentrations of aqueous Chenopodium album extract (2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5 and 6.0%) and gamma radiation at a dose of 6 Gy were examined for their efficacy in inducing resistance of sunflower plants against fusarium root rot caused by F. solani MG‐3 by evaluation of some physiological and biochemical parameters of infected and healthy plants under greenhouse conditions.
• The pre‐treatment of sunflower seeds with 6% C. album extract and 6 Gy gamma radiation reduced fusarium incidence from 47.49% to 28.25%. Also, nucleic acid content, ascorbic acid, α‐tocopherol, anthocyanin, total flavonoids, proline, glycine betaine and lipid components significantly increased in irradiated infected plants treated with C. album extract, while H₂O₂ content and lipid peroxidation markedly decreased as compared with healthy control plants. Moreover, treatment with gamma radiation reduced the amount of unsaturated fatty acids through accumulation of saturated fatty acids compared with non‐irradiated plants; treatment with C. album extract also enhanced the content of unsaturated fatty acids, with a noticeable decrease in saturated fatty acid content.
• Hence, C. album extract and gamma radiation can be used to enhance biological control of fusarium root rot of sunflower plants.

脂肪母鸡提取物和γ射线处理对向日葵植物镰刀菌根腐病的保护作用

• 造成向日葵作物经济损失的最严重的疾病之一是茄镰刀菌（Fusarium solani）引起的镰刀菌根腐烂。植物提取物和电离辐射提供了替代的对环境安全的控制剂，这些控制剂在控制和克服这种真菌性植物病原体方面具有重要作用。
• 在本研究中，研究了6 Gy剂量的不同浓度的藜藜水溶液提取物（2.0％，2.5％，3.0％，3.5％，4.0％，4.5％，5.0％，5.5％和6.0％）和伽马射线辐射在6 Gy剂量下的功效。通过评估温室条件下受感染和健康植物的一些生理和生化参数，诱导向日葵植物对茄红镰刀菌MG-3引起的镰刀菌根腐病的抗性。
• 用6％C.专辑提取物和6 Gyγ射线预处理葵花子可使镰刀菌的发病率从47.49％降低到28.25％。同样，用C. album提取物处理的受辐照植物中的核酸含量，抗坏血酸，α-生育酚，花色苷，总类黄酮，脯氨酸，甘氨酸甜菜碱和脂质成分显着增加，而H ₂ O ₂含量和脂质过氧化显着降低，与健康对照植物相比。此外，与未辐照植物相比，伽马辐射处理通过积累饱和脂肪酸减少了不饱和脂肪酸的数量；用C.相簿处理 提取物还提高了不饱和脂肪酸的含量，饱和脂肪酸含量明显降低。
• 因此，C。album提取物和γ射线可用于增强向日葵植物镰刀菌根腐病的生物防治。
