Abstract:
In this study was conducted to evaluate the effect s of silver nanoparticles extracted from Chaetomorpha aerea kutz, on seed germination application for Solanum lycopersicum L. crop plant. AgNPs was carried out by different instrument and technique. It includes visual observation ultraviolet–visible spectroscopy (UV–Vis), Fourier transform infrared (FTIR), powder X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray analysis (EDAX), dynamic light scattering (DLS), aqueous medium containing silver nanoparticles showed absorption of the peak. Were tested Germination characteristics of Silver nanoparticles on plant growth parameters such as shoot and Root length Seed of germination and% Germination contents of economic important S. lycopersicum L. biological research due to their present study we have studied positive control and negative control of the germination of the seeds and impact of two concentration (0.5, 1.0, mg/L) of silver nanoparticles (AgNPs) and two concentration (100 and 500 mg/L) the concentration as compared to control (without AgNPs). We also examined the effect of silver nitrate (AgNO3), which showed that at 0.2 concentrations the plant root and shoot height was maximum observed when compared to positive and negative control and at 0.1concentration showed maximum seed germination% was observed when compared to positive and negative control in all the tested concentration.
