The effect of anatase nanoparticles (TiO2) on pepper seed germination (Capsicum annum L.).

Nanotechnology collectively describes technology and science involving nano scale particles (nanoparticles) that increases the scope of investigating and regulating the interplay at cell level between synthetic materials and biological systems. The experiment to evaluate the effect of different concentrations of nano-anatase on germination parameters of pepper as a factorial design with eight replications was performed in Shahid Chamran University of Ahvaz, department of Horticulture science. In addition, seeds soaked at four concentrations (3.5, 5.5, 7.5 and 9.5 percentage) nano-anatase for 24 and 48 hour. At the end of the experiment, the percentage of germination, germination rate index, radicle and plumule length, fresh weight of seedlings and vigor index were evaluated. The results showed that increase in the concentration of nano-anatase, caused to a significant increase in the percentage of germination, germination rate index, radicle and plumule length, fresh weight and vigor index of seedlings. The best concentration of nano-anatase was 7.5℅ nano-anatase.
