Metal nanoparticles are newly emerging alternate source of carriers to transmit and maintain the
desired plant food sources available for plant growth and development. Their accumulation in
agriculture lands is accompanied by both positive and negative effects on plants. Considering their
impact on plants, it is necessary to evaluate them on seed germination and seedling growth. The main
objective of this study was to investigate whether the treatment of Cicer arietinum seeds with
relatively low concentrations of bioengineered ZnNPs and zinc metal would affect the seed
germination and seedlings growth. Zinc nanoparticles were characterized by transmission electron
microscopy (TEM). There were differences in germination (2%), root length (0.18cm), shoot length
(0.17cm), fresh weight (0.52cm) and dry weight (0.03cm) between seeds grown in control and Zn
NPs. There also existed significant differences in germination (2.67%), root length (4.94cm), shoot
length (1.29cm), fresh weight (0.50cm) and dry weight (0.09cm) between seeds grown in control and
ZnSO4. Cicer arietinum seeds grown in zinc nanoparticles showed increase in germination, shoot
length, root length, fresh weight and dry weight, whereas seeds grown in zinc metal decreased growth.
Our findings suggest that bioengineered zinc nanoparticles showed positive effect on seedlings
growth.
