Influence of TiO2 nanoparticles on growth, chemical constituents and toxicity of fennel plant

الملخص EN

The present work is carried out to evaluate the effect of TiO2 nanoparticles treatments on fennel (Feoniculum Vulgare Mill) plants.

The plants were sprayed with different concentrations of TiO2 nanoparticles 2, 4 and 6 ppm.

In most cases, the tallest plants, the highest number of branches, the highest fruit yield per plant and the highest values of Pigments, Carbohydrates, Sugars nitrogen, phosphorus, potassium were obtained from the treatment of 6 ppm TiO2 nanoparticles of fennel.

Results showed that sprayed fennel plant with concentrations of TiO2 nanoparticles 0, 2, 4 and 6 ppm is safe and enhanced chlorophyll synthesis and consequently enhanced photosynthesis.
