Title

The potential of green and chemical synthesized nano particles to induce oxidative stress in Allium cepa L.

Pages

  87-99

Abstract

 With respect to the rise rate of the production and release of nanoparticles in nature, it is important to note the possibility of toxicity and oxidative damage to the plant ecosystem. Hence, this research was aimed to compare the biochemical and anti-oxidative indices of Onion treated with different concentrations of two types of Silver nanoparticles (Green synthesis and chemical synthesis) and investigating the probability of Oxidative stress induction. In this study, the color of the leaf extract turning from pale yellow to dark brown, due to surface plasmon resonance of Silver nanoparticles, indicated the successful synthesis of Silver nanoparticles. The absorption spectrum of the synthesized Silver nanoparticles showed a peak with λ max of 410 nm. TEM images revealed a uniform size of the synthesized particles, with almost spherical shape and the size range between 3 to10 nm, with an average of 5. 8 nm. XRD analysis revealed that the green synthesized Silver nanoparticles were crystalline in nature. According to the results, both antioxidant enzymes represented linear increases in exposure to the chemical nanoparticles. Both nanoparticles caused increasing in lipid peroxidation, but the green synthesized nanoparticles had no significant difference compared with the control. The most Phenol content belonged to chemical nano-silver (15. 16 mg Gallic g-1 FW at the concentration of 0. 05 gr l-1 ) and the least value to the control (4. 1 mg Gallic g-1 FW). The antioxidant activity of chemical nanoparticles was 8 times more than the green nanoparticles. According to the results of this research, green nanoparticles didn’ t have an oxidative effect on onion. However, some stimulus effects were revealed. It is worth noting that, the chemical nanoparticles, provoked plant defense reactions, by inducing Oxidative stress, besides the inhibitory effect was dose-dependent.
