Nano-Iron and Nano-Zinc Induced Growth and Metabolic Changes in Vigna radiata

The widespread industrial use and consequent release of nanosized iron (nFe3O4) zinc oxide (nZnO) particles into the environment have raised concerns over their effects on living organisms, including plants. These nanoparticles are source respective metal ions although plants require both Fe Zn for proper growth, excessive levels these metals toxic to them. A better understanding also offers an opportunity useful applications in agriculture. present work evaluates changes seed germination, plant photosynthetic capacity, biomolecules antioxidant enzymes Vigna radiata (L.) Wilczek when grown presence nFe3O4 (size 1–4 nm) nZnO 10–20 compared control were hydroponically up 14 days at two different concentrations nanoparticles, viz. 10 100 mg/L. Inductively coupled plasma mass spectrometry (ICP-MS) results established that V. can accumulate shoots with high efficiency. indicated had a favourable effect radiata, whereas no apparent benefit or toxicity was observed tested concentrations.
