The Effect of Biologically Synthesized Silver Nanoparticles on the Germination and Growth of Cucurbita pepo Seedlings

Silver nanoparties were synthesized from aqueous solution of silver nitrate, with different molar ratio of silver (0, 1, 2, and 3M), using leaf extraction of Neem as well as Saisban. The effect of silver nanoparticles of Neem and Saisban solution on seed germination, hypocotyls and semi root lengths of Cucurbita Pepo was investigated. The Cucurbita Pepo seeds were immersed for 20 minutes in silver nanoparticles solution of Neem and Saisban along with distilled water as control. The seeds allowed to grow in petri dishes. The results show no effect on growth percentage while a remarkable change in seeding speed and length were observed for all the different concentrations of silver nanoparticles. Silver nanoparticles that are treated with Saisban increase the seeding speed of Cucurbita Pepo, while the highest length of hypocotyls and semi root were noted for seeds treated with silver nanoparticles prepared using Neem.
