Now a day’s green synthesis of silver nanoparticles (AgNPs) from plants has an important role in biomedical science, drug discovery and also in biological field. In this investigation, we synthesize AgNPs using the aqueous solution of the leaf extract of 4 indigenous plant samples such as –Abroma augusta, Barringtonia acutangula, Dillenia indica & Eupatorium odoratum in room temperature (35±2°C). After that, formation of AgNPs were confirmed by UV-VIS spectrum, the answered (435, 445, 430 & 440 nm), respectively. The average size of the AgNPs also confirmed by Particle size analyser (PAS), the B. acutangular species showed the best quality of silver nanoparticles among the other plant extracts. FTIR analysis showed that five biomolecule groups like phenols, aromatic, alkyne, alkane and alkene were found in among these plant samples. Our findings suggest that the seed germination percentage, relative seed germination rate, relative shoot & root growth and germination index of the tested plant depends upon concentration gradient of synthesize AgNPs. At 0.6 mg/ml concentration, the tested plant samples give the best favorable growth condition.
