Peculiarities of growth and development of Pinus sylvestris L. when cultivated in the medium containing copper nanoparticles

At present, ecologists, physiologists and other scientific researchers are facing the problem of little knowledge of the action of nanomaterials, which makes it impossible to assess the potential risks of using nanomaterials. The widespread use of copper nanoparticles, in particular the use in the presowing treatment of plant seeds, makes it relevant to study the characteristics of plant growth when copper is introduced into the medium. In the present work, the growth features of Pinus sylvestris L. — Scots pine, were studied during cultivation in a medium containing copper nanoparticles. Research has shown that the cultivation of P. sylvestris L. in a medium containing copper nanoparticles at concentrations of 0.025–0.1 M completely blocks the development of the root system. Cultivation in medium containing copper nanoparticles at a concentration of 6.25 mmol reduces the length of the root to 27.9 ± 3.8 mm, and also reduces the mass to 19.6 ± 1.9 mg. (paper)
