• Abstract:

  The fast development of
  nanotechnology (NT) and the application
  of metal and carbon nanoparticles (NPs) to
  plants, disturbs their metabolic processes
  and influences positively or harmfully the
  morphophysiological responses. Numerous
  types of NPs employed as plant growth
  regulators, nanopesticides and nanofertilizers,
  have shown promising evidence so far for
  increasing crop yields, and managing salt and
  water stress at the field. Some metal-based
  NPs are considered a biosafe material for
  organisms. Earlier studies have demonstrated
  the potential of some NPs for seed germination
  stimulation and plant growth, as well as disease
  suppression and plant protection by virtue of
  their antimicrobial activity. In this article both
  positive and negative effects of metallic and
  carbon NPs on plant growth and metabolism
  are documented. Uptake, translocation, and
  accumulation of NPs by plants depend upon
  the distinct features of the NPs as well as on
  the physiology of the host plant. This review
  contributes to the current understanding
  of the outcome of NPs in cultivated plants,
  their absorption, translocation, physiological
  responses, and mitigation impacts to various
  adverse conditions on plant growth. The
  results presented here correspond to the
  evaluation of NPs in more than 30 crops,
  belonging to 19 plant families.
