| Summary: | Fusarium species are significant pathogens in many crops, including garlic (Allium sativum), threatening yield and food safety through mycotoxin production. This study investigates the physiological, phytochemical, and nutrient responses of garlic genotypes (Local-Konya, Babaeski-Kırklareli, and Iranian-Balıkesir) to Fusarium proliferatum infection. Phenolic compounds, antioxidant activity, protein content, and macro- and microelement levels were assessed in healthy and infected garlic genotypes. Infection by F. proliferatum led to a significant increase in phenolic compounds, especially resveratrol and catechin. The Iranian-Balıkesir genotype exhibited the highest response, showing a 110.9% rise in total phenolic content. Regarding antioxidant activity, 2,2-Diphenyl-1-picrylhydrazy (DPPH) inhibition also rose in all genotypes with the rate of 41.57–55.5% in diseased groups in comparison with healthy groups. However, the protein content of garlic was declined by infection of F. proliferatum in all genotypes. Elemental analysis revealed that there were notable drops in potassium and calcium levels, particularly in Local-Konya genotype, but the other elements in plants either increased or decreased accordingly. It was observed that garlic genotypes responded differently to F. proliferatum infection in organic acid components. These findings highlighted that F. proliferatum infestation in garlic enhanced phenolic production and antioxidant activities as a defense mechanism, but the amount of nutrient content of plants according to fertilization will also affect developing resistance to disease physiologically. |
