Effect of silver, copper and iron nanoparticles on wheat germination

The effect of the exposure of wheat (Triticum aestivum) seeds to silver, copper and iron nanoparticles on germination and seedling vigor index has been studied under laboratory conditions. Seeds were exposed to silver, copper and iron nanoparticles under various conditions. Germination percentage and root shoot length were calculated. The results showed a reduction in germination percentage on exposure to silver and copper nanoparticles while maximum germination percentage was on application of iron nanoparticles. Similarly while root and shoot growth was also enhanced under iron nanoparticles application while severereduction in root and shoot length was observed on exposure to copper nanoparticles. So copper has inhibitory while iron has stimulatory effect on wheat germination and growth.
