Abstract

Medicinal plants consumption is used in various countries for treatment disease and food complementary. Nanotechnology is one of developing sciences in the world. The research performed in previous studies showed that properties of medicinal plants could be strongly affected by nanoparticles that have polluted the environment. In this study, we investigated effects of nickel nanoparticles on root and shoot elongation, relative water content (RWC), photosynthetic pigment, total ash, antioxidant activity of Coriandrum sativum L. The results showed that nickel nanoparticle decreased the RWC, root and shoot elongation, the content of photosynthetic pigments, total ash. In addition, although the nanoparticles decreased the antioxidant activity. The results of this study have shown that, nickel nanoparticles have toxic effects on C. sativum L plant. This research could be a turning point in the field of nanotechnology research in medicinal plants. Other researchers can survey by themselves any aspects of the study with more focusing on molecular mechanisms.
