Phytosynthesized silver nanoparticles enhance aged rice seeds’ germination and starch metabolism. a Seeds without silver nanoparticle priming treatment have lower metabolic activity because of slow water uptake, and starch is hydrolyzed slowly; as a result, sugar levels are low in the initial stage of imbibition, resulting in slow seed germination and growth. b Silver nanoparticle seed priming enhances seed germination.
