Morphophysiological features of wheat (Triticum aestivum L.) seedlings upon exposure to nickel nanoparticles

The intensive development of nanotechnologies determines the need for the investigation on the patterns of biological impact of technogenic nanomaterials. The analysis of the researches reveals a wide range of toxicity manifestations when nanocompounds affect plants, which depends on the physical properties of the nanoparticles (dimensions, shape, catalytic activity, concentration). The relevance of the studies on the concentration effects of nanoparticles is due to the insufficient knowledge of their interaction with the plant cell, and, consequently, the need to determine the dose-effect relationship for each class of nanoparticles and various bio-objects. This paper presents the results of a comprehensive study of the effect of nickel nanoparticles (NP Ni0, Δ50 = 5 nm in size) when used at different concentrations on growth, content of pigments, flavonoids and proline, photosynthesis and transpiration intensity of ten-day-aged wheat seedlings ( Triticum aestivum L...
