| Summary: | Заглавие с экрана The content of nutrients, in particular, nitrogen and potassium, in the tissues of seedlings is one of the main physiological indicators associated with production processes in plants. In our study, we showd the influence of nickel nanoparticles concentration on the content of К+ and NO3- ions in the extracts obtained from the wheat seedlings tissues. It was revealed that the addition of suspensions of Ni nanoparticles with an average size of 80 nm at the concentration range of 30...300 mgL-1 did not have a statistically significant effect on mineral state of the seedlings. The electrical conductivity of the extracts remained at the level of 580±29 [mu]S⋅cm -1 , while the content of К+ and NO3- ions was 1814 ± 214 and 1521 ± 78 mEq/kg of dry weight, respectively. Although, there were no obvious trends in the studied parameters in the concentration series of nanoparticle suspensions, while adding ions of Ni2+ lead to 15…45% increase of estimated parameters for seedlings. |
