Abstract: (7 Views)
As the best source of selenium for humans and animals, plants, absorb this element from the soil and enter the food chain. Selenium nanoparticles have been introduced as stable nanoparticles for use as plant fertilizers. Considering the beneficial role of selenium in plants, its essential need in human and animal bodies and its toxic effects in high concentrations, in the current research the effects of selenium (bulk and nano forms) on growth, physiological and antioxidant characteristics of spinach under greenhouse conditions was investigated. The experiment was carried out in a completely randomized design in three replications. The factors were included foliar spraying of nano selenium (5, 10 and 20 ppm), sodium selenate (5, 10 and 20 mg/L) and distilled water (control plants). Based on findings, enhancing the levels of both treatments (up to 20 ppm and mg/L) led to an increase in the areal organ and root length, leaf number, leaf and root dry matter, proline content, and the activity of antioxidant and peroxidase enzyme. Ion leakage was declined under different levels of nano-Se and only at 10 mg/L of sodium selenate. In contrast, the highest ion leakage was recorded at 10 mg/L of sodium selenate. Malondialdehyde content and the activity of catalase enzyme were improved only at 5 (ppm and mg/L) level of both treatments. Rising the levels of sodium-selenate up to 20 mg/L and applying 5 ppm of nano-Se boosted flavonoid content. Phenol was also elevated under different levels of nano-Se and only at 10 mg/L of sodium selenate. However, this trait was alleviated at other levels of sodium-selenate.
