Comparative analysis of morpho-physiological features of Triticum vulgare sprouts after exposure to metal nanoparticles

In this article violation of the mineral metabolism of plants as a result of secondary contamination with heavy metals (HM), which at high concentrations have a toxic effect on a wide variety of physiological processes, occupies a central place in the problem of the resistance of plant organisms to unfavorable environmental factors. Nanoparticles based on iron, copper and nickel are of considerable interest. The study of the mechanisms of plant adaptation to structurally different nanometals (NM) from the position of changing a number of physiological and biochemical parameters is relevant for a more complete understanding of the adaptive capabilities of organisms in conditions of technogenic nanomaterials. Analysis of the content of photosynthetic pigments allowed the formation of consistent ideas about the selectivity of the effect of nanometals on the components of the pigment system of seedlings, depending both on the composition of the metal and on its concentration...
