Not AvailablePearl millet and clusterbean foliar sprayed with 100 µg/
mL Zn as nano-zinc oxide increased shoot while root biomass
decreased. The amount of total C exuded through roots also
decreased. Reduction in root biomass and exudates together
accounted for only about 16 and 38% of the additional C
accumulated in shoot biomass. Therefore there is all likelihood
that part of the enhanced C accumulated in shoot may be due
to enhanced photosynthesis. Such a positive influence of
nano-ZnO could have been due to protection of the cellular
membrane from the UV-radiation as evident from less
malondialdehyde content in the treated plants in our
experiment.Not Availabl
