Comparative investigation of effects of phytosynthesized and mycosynthesized based silver nanoparticles on the growth of maize

Effects of phytosynthesized and mycosynthesized based silver nanoparticles on plant growth parameters such as shoot and root lengths, leaf surface area, chlorophyll, RWC, MSI, SSC, carotenoid, SOD and POD contents of corn (Zea mays L.) was probed in the present research. The study was carried out with three replications. 4 dose of silver nanoparticles (20, 40, 60 and 80 ppm) were used. After germination, daily supply with 15 ml from each concentration was carried out for 12 days during plant growth. The results showed that small dose of silver nanoparticles enhanced the growth, while the higher dose induced the inhibitory effect. However, 40ppm of phytosynthesized NPs showed best results on increasing the shoot and root lengths, leaf length, chlorophyll, carotenoids SOD and POD contents of the tested crop plants while mycosynthesized showed best results at 60ppm dose on all the growth parameters as compared to the control. The present study illustrate the effects of phytosynthesized and mycosynthesized silver nanoparticles on maize growth parameters
