Abstract
To check the impact of biosynthetic agglomerate form of AgNPs on plant growth, synthesised AgNPs was characterized by using UV- Visible spectroscopy. Antifungal assay was performed by poisoned food method and plant growth was evaluated by using shoot length (cm), Leaves (no. /plant), shoot dry wt./plant (g), % seed germination and photosynthetic properties.AgNPs exhibit absorption spectra at 420 nm and showed antifungal activity against A. niger and F. oxysporium. Significant positive effect was found over Gossypium hirsutum.The biosynthesised AgNPs exert significant antifungal activity against F. oxysporium. AgNPs show positive effect over shoot length (cm), Leaves (no. /plant), shoot dry wt./plant (g), % seed germination and photosynthetic properties of both plants. The produced AgNPs was in agglomerate form and low in concentration, so they were safe for plant and environment.
Keywords: Green synthesis of silver nanoparticles, Antifungal activity, plant growth promotion activity.
