The demand for healthy foods with high functional value has progressively increased. Carbon nanoparticles (CNPs) have a promising application in agriculture including the enhancement of plant growth. However, there are few studies on interactive effects CNPs and mild salinity radish seed sprouting. To this end, effect priming 80mM biomass, anthocyanin, proline polyamine metabolism, antioxidant defense system under growth condition (25 mM NaCl). results indicated that nanopriming along stress enhanced sprouting its capacity. Priming boosted capacity by increasing metabolites such as (polyphenols, flavonoids, polyamines, proline). understand bases these increases, precursors key biosynthetic enzymes anthocyanin [phenylalanine, cinnamic acid, coumaric naringenin, phenylalanine ammonia lyase, chalcone synthase (CHS), cinnamate-4-hydroxylase (C4H) 4-coumarate: CoA ligase (4CL)], [pyrroline-5-carboxylate (P5CS), dehydrogenase (PRODH), Sucrose, Sucrose P synthase, invertase) polyamines [putrescine, spermine, spermidine, total arginine decarboxylase, orinthnine S-adenosyl-L-methionine spermidine spermine synthase] were analyzed. In conclusion, potential to further stimulate salinity-induced bioactive compound accumulation sprouts.
