Impact/effect
Reference(s)
Colloidal solutions of cu and
Zn NPs
–
Drought
Seed
treatment
1 part of colloid
solution to 100 parts
of water
Greenhouse
study
Reduction in drought stress on plants,
increase in the activity of antioxidative
enzymes, reduction in TBARS accumulation, stabilization of photosynthetic pigments, and increase in relative
water content of leaves
Taran et al.
(2017)
Fe
3 O
4 NPs
6.8
Heavy metals
(Pb, Zn, cd, and
cu)
Seed
treatment
2000 mg L
À1
Petri dish
assay
Significantly decreased root growth
inhibition and reduced and alleviated
oxidative stress induced by the heavy
metals
Konate et al.
(2017)
Magnetite NPs
5–20
Heavy metals
(cd and Cr)
Sand
amendment
1000 mg kg
À1
Pot assay
Enhanced in root length and cadmium
and chromium accumulation diminished and the metal toxicity alleviated
López-Luna
et al. (2016)
Si NP
20–95 UV light
Seedling
dip
10
μM
Growth
chamber
Effectively alleviated UV-B stresses on
wheat seedlings through NO-mediated
triggering of antioxidant defense system and counterbalance reactive oxygen species-induced damage to
photosynthesis
Tripathi
et al. (2017)
Analcite NPs
100
Drought
Soil
amendment
500, 1000, and
1500 mg L
À1
Pot assay
Increment in seed germination, seedling growth criteria, as well as content
of photosynthetic pigments under
stress; sharp accumulation of protective
antioxidants (flavonoids, carotenoids)
