The aim of this research is to study different concentrations of Silver and Zinc oxide bulk and nanoparticles on germination of the Faba bean plant in the pollution and plant Ecology laboratory at the science faculty University of Aleppo (Syria) during the between November and December 2019. After preparing a series of concentration of zinc nanoparticles, zinc oxide (100, 200, 400 and 800 mg/l) and concentrations of silver nanoparticles, silver nitrate (50,100 and 200 mg/l). Seeds were soaked for 24 hours and distributed on petri dishes at a rate of six seeds per dish and six replicates per ncentration.The results showed no effect of zinc oxide nanomaterial on the percentage and speed of seed germination. However, it played a positive catalytic role where it led to a significant decrease in the length and weight of shoot and root systems. Whereas, the effect of silver nanoparticles was negative on all seed germination indexes which showed a decrease in the percentage and speed seed germination. This decrease was significantly in the length and weights average
