Effect of iron oxide nanoparticles on morphology and physiology of mung bean (Vigna radiata)
The aim of present work was to study the effect of iron oxide nanoparticles on the morphology and physiology of Vigna radiata. Seeds of this plant were raised at different concentrations of iron oxide nanoparticles (10, 50, 100, 500, 1000 mg/l). It was revealed that presence of iron oxide nanoparticles affected the growth of Vigna radiata at different concentrations. Root and shoot length was found increased as the nanoparticle concentration increased from 10 mg/l-1000 mg/l so we can say that iron nanoparticles had stimulatory effect on growth of plants. Total chlorophyll and carbohydrate content was increased at 15th day in comparison to 7th day. But content of soluble protein was highly correlated with age of plant i.e. content of soluble protein decreases with increasing of age. So, content of soluble protein was higher at 7th day in comparison to 15th day.
