PHYSIOLOGICAL RESPONSES OF CROP PLANTS TO METAL AND CARBON NANOPARTICLES
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.
