Intervention effect Fe2O3 nanoparticles at 0.25 to 1.5 mg/mL inhibited mycelial growth of V. dahliae in vitro, with variable inhibition across concentrations.
Intervention effect The greatest in vitro mycelial growth inhibition of V. dahliae (88.5%) was at 0.75 mg/mL Fe2O3 nanoparticles.
Intervention effect Root priming with Fe2O3 nanoparticles increased marigold root length by 32%.
Intervention effect Root priming with Fe2O3 nanoparticles increased marigold shoot length by 34%.
Intervention effect Root priming with Fe2O3 nanoparticles increased marigold fresh weight by 42%.
Intervention effect Root priming with Fe2O3 nanoparticles increased marigold dry weight by 18%.
Intervention effect NP treatment enhanced photosynthetic pigments (chlorophyll a, chlorophyll b, carotenoids) and relative water content in marigold.
Intervention effect NP treatment enhanced osmolyte (proline and sugar) accumulation in marigold.
Intervention effect Nano-priming significantly decreased H2O2 and malondialdehyde levels in marigold, indicating less oxidative stress.
Intervention effect Nano-priming decreased relative electrolyte leakage in marigold.
Association Histological analysis showed decreased colonization of marigold root vascular tissue by V. dahliae.
Intervention effect Fe2O3 nanoparticle application upregulated the carotenoid pathway genes phytoene synthase and phytoene desaturase in marigold.
Intervention effect Fe2O3 nanoparticle application upregulated the carotenoid pathway genes beta cyclase and epsilon cyclase in marigold.
Intervention effect Biosynthesized Fe2O3 nanoparticles successfully inhibited V. dahliae growth in marigold.
Intervention effect Biosynthesized Fe2O3 nanoparticles increased resistance in marigold plants.
Observation Synthesis of the Fe2O3 nanoparticles was confirmed by a UV-visible absorption peak at 275 nm.
Observation FTIR validated functional groups on the nanoparticle surface, and SEM showed a spherical nanoparticle morphology.
Observation XRD showed a crystalline Fe2O3 nanoparticle structure with an average size of 42 nm.
Observation EDX showed the Fe2O3 nanoparticles to contain Fe 71.6% and O 15.9%.
