1. Ag NPs
Enhanced root growth, biomass
accumulation and evapo-transpiration;
protected plants from heavy metal
stress and AMF infection

Enhanced carbohydrate content and
antioxidant potential and overall yield
Arora et al. (2012)

fullerols
Enhanced relative water content,
growth, metabolism, and accumulation
of anticancerous and antidiabetic
metabolites; increment in the number
of fruits, fruit length, and fruit weight
Kole et al. (2013)
4. CeO 2
Enhanced biomass accumulation,
root–shoot length, fresh water content,
macro- and micronutrient absorption,
activity of antioxidant enzymes,
catalase, and ascorbate peroxidase
Morales et al. (2013),
Trujillo-Reyes et al. (2013),

vegetative growth and fruit yield;
alleviated stress induced by
hyperaccumulation of cadmium
Khodakovskaya et al. (2012),
Chai et al. (2013), Husen and
Siddiqi (2014)
6. C 60 fullrenes

retention, seedling growth, and
phytochemical accumulation;
alleviated stress induced by exogenous
pesticide
Remya et al. (2012), TorreRoche et al. (2013), Husen and
Siddiqi (2014)

differentiation, and resistance against
oxidative stress

10.3.1 Mechanism Underlying the Positive Effect of NPs
on Plants
Exposure of some type of NPs can have positive effect on the growth of plants as
discussed (Table 10.1). Some studies have even documented the probable mechanism underlying the growth-promoting abilities of NPs.
