Megjegyzések:	We still lack knowledge concerning the mode of action of engineered nanoparticles in agriculture. The key point of this study is to investigate the role of nano-silica (NS) to enhance the seed germination and growth development of common bean. Four different concentrations of NS suspensions (100, 200, 300, and 400 mg L-1) were supplemented to nursery and growth media. Our results showed that 300 mg L-1 of NS increased the final germination percentage from 82.3 to 97.7%, the germination speed from 24.9 to 36.2% / day, the vigour index from 14.3 to 20.2, and decreased the mean germination time from 4.3 to 3.3 days. Strikingly, 300 mg L-1 of NS increased the root dry mass of common bean seedlings by 93.5%,the shoot dry mass by 78.7%, the root length by 32.7%, and the shoot length by 13.2% versus untreated seedlings.This study proved that NS is able to improve the germination and growth of common bean as a result for altering some physiochemical reactions after penetrating the seed coat.
