PHENOTYPIC VARIATION AND THE POLYPHENOLS CONTENT ALTERATION OF CELOSIA CRISTATA DUE TO CHRONICALLY INDUCED MUTATION USING ETHYL METHANE SULPHONATE

Celosia cristata is one of the floricultural commodities which also beneficial as a medicinal plant. Mutation techniques can effectively increase morphological diversity and biochemical content C. cristata. Chronically induced mutation using ethyl methane sulfonate (EMS) was first applied to properties. This study proposes modifying induction technique that allows plant material be exposed mutagen (a substance causes mutations) for long time, with minimum damage genetic cell components. Thus, this modification method produce more new plants favorable traits breeding program. The present aims evaluate polyphenol emerge due chronic EMS. seeds were immersed in EMS solution consisted 4 treatment levels, namely: 0% (Control); 0.0278% 6 hours; 0.00278% 1 day; 0.000278% 2 days. analysis Folin-Ciocalteu flavonoid based on colorimetric-AlCl3 method. antioxidant activity estimated through two assays, including 2,2-diphenyl-1-picrylhydrazyl (DPPH) Ferric reducing power (FRAP). Chronic shown affect growth In addition, changes morphology such intensity anthocyanin coloration at base, leaf shape, color, flower shape occurred mutations. increased content, activity, according FRAP method, summary, promising Henceforth, programs desirable traits.
