THE USE OF MORPHOMETRIC AND BIOCHEMICAL INDICES OF TEST-CULTURES TO ESTIMATE THE COPPER NANOPARTICLES TOXICITY
The results of the copper nanoparticles influence as related to morphometric indices and composition of the pigmentary apparatus of Lepidium sativum, Avena sativa and Raphanus sativus plants are submitted in the article. Rapid accumulation of experimental materials, demonstrating the uniqueness and diversity of nanoparticles manifestations, even when they consist of one and the same chemical element, is being observed nowadays. The properties depend not only on physical nature, methods of obtaining, size and structure of nanoparticles, but also on the biological model on which the tests are carried out. The results of the study show that the most informative indicators of the toxic effect of copper nanoparticles on plants are the Raphanus sativus L. germination and the composition of the pigmentary complex of Avena sativa L. leaves.
