Iron nanomaterial is used in many applications. It is also characterized by the spread of pollution at high concentrations. Effect of F3O4(NPs) on three plants for the purpose of showing Chlorophyll and carotenoid responses and protein content as effective biomarkers for increasing the concentration of nanomaterials in the ecosystem. Different doses of F3O4(NPs) ranging from (0-600 mg / L) were used, the content of a and b Chlorophyll, a and B Carotenes and protein were measured in three plants (Lepidium sativum, Peganum Harmala and Portulaca oleracea).) in Najaf, Iraq for 3 months in 2022. The results showed different concentrations (0-600 mg / L). To compare the studied plants in chlorophyll concentrations when using concentrations (0, 150, 300, 600) mg / L, 300 mg / L was the highest value and 600 mg / L was the lowest value. The highest values appeared in L. sativum, the lowest values appeared in Portulaca oleracea, and the comparison of carotene content was similar to that of chlorophyll in L. sativum. As for P. harmala, it was not affected significant differences. While P. oleracea recorded the highest value at 600 mg / L and the lowest value at 300 mg / L, and this indicates the variation in the response of the studied plants to F3O4(NPs) doses according to different plant species. The results indicate that an insufficient supply of F3O4(NPs) (150 mg / L) can be a plant growth stimulator and the results can be used in practical applications to increase production and improve crops as a fertilizer. Whereas, treatments with high concentrations inhibit antioxidants, causing a deficiency of growth activity in plants. [ABSTRACT FROM AUTHOR] |
