The effect of two sterilization substances (Mercuric chloride and sodium hypochlorite) on the
germination rate, and Multiwall carbon nanotubes on both seed germination and seedling
growth, was studied in tomato plant (lycopersicum esculantum var.Arka Vikas). Surface
sterilization of mature seeds using 4% sodium hypochlorite (Naocl) stimulated the germination
rate; although0.1% mercuric chloride (HgCl2) completely inhibits the tomato seed germination.
Multi walled Carbon nanotubes shows the positive effect on the tomato seed germination and
plant growth when compared to the normal medium, the maximum germination rate and
seedling growth was observed at 40 ?g/ml concentration of carbon nanotubes.
