ecently, scientific community dedicated to the
development of sustainable agricultural techniques have
focused their attention and concern towards the application
of engineered nanoparticles (ENPs), since the use of metal
oxide nanoparticles could result in their accumulation in soil,
threatening higher terrestrial plants. ENPs are able to interact
with biomolecules, creating functional nanosystems for
transportation within cells, and leading to the study of their
potential applications in the field of Plant Biotechnology. On
the other hand, the physical and chemical features of carbon
nanomaterials such as multi-walled carbon nanotubes
(MWCN) and graphite oxide (GO) NPs, had been used to
promote plant’s growth, and seeds germination. Therefore,
this report focus on the application of copper nanoparticles
(Cu NPs), iron oxide (Fe
2
O
3
NPs), MWCN and GO NPs, to
seeds and plants of
Solanum lycopersicum, Capsicum
annuum, Cucumis melo
and
Rhapanus sativus,
to evaluate
germination and plant growth characteristics. Imbibition of
tomato seeds in Cu NPs significantly improved germination
(14.3%), seedlings vigour (69%), plumule and radicle length
increased by 20% and 95% respectively compared to control.
In pepper seeds, Cu NPs also promoted vigour (118%) and
seeds germination (10.2%); improved seedlings growth was
reflected by longer plumule and radicle length (8% and 15%
correspondingly). For
C. melo
Fe
2
O
3
NPs also enhanced vigor
(30%), germination (16.5%), plumule and radicle length by
20% and 95% respectively compared to control plants. On
R. Sativus
MWCN and GO NPs reduced plants growth and
vegetative development, suggesting a phytotoxic effect by
these carbon NPs.
