Abstract

This study aims to obtain the optimum concentration of 2,4-D and BAP plant growth regulators (PGRs) to induceChrysanthemum callus in light and dark conditions. The method used is an experimental method in the laboratoryusing a Completely Randomized Design (CRD) with 4 treatment of 2,4-D + BAP concentration combinations. Theculture was incubated under different lighting conditions for 45 days after planting. The parameters observedincluded ctexture and color of callus, other responses produced by explants, size, fresh weight and dry weight ofcallus. Data were analyzed descriptively. The results showed that 4 ppm 2,4-D + 0.5 ppm BAP treatment was thebest combination in inducing Chrysanthemum callus in both light and dark conditions. In bright conditions, mostof the callus were dark green and dark brown with a compact texture, callus size of 1.36 cm, and the highest freshweight and dry weight of callus were 0.62 gram and 0.17 gram respectively. Meanwhile, in the dark conditionsmost of the callus were light green and light brown with a compact texture, callus size 1.18 cm, and the highestfresh weight and dry weight of the callus produced were 0.51 grams and 0.15 grams, respectively. Keywords: Callus, Chrysanthemum morifolium, 2,4-Dichlorophenoxyacetic acid (2,4-D), 6-Benzylaminopurine(BAP)

Abstract

Chrysanthemum morifolium contains flavonoids which have antioxidant properties and was useful in treating various diseases. The production of flavonoids from plants can be done in vitro through callus culture. Auxin 2,4-D growth regulators and organic compounds such as coconut water added to the media can affect the success of callus formation and secondary metabolite synthesis. The purpose of this study was to obtain the best treatment of 2,4-D concentration and coconut water that can increase the growth and total flavonoid levels of C. morifolium callus cultures. The method used in this research was the experimental method completely randomized design (CRD) with 8 treatments, namely 1 ppm 2,4-D + 10% coconut water (CW); 2 ppm 2,4-D + 10% CW; 3 ppm 2,4-D + 10% CW ; 4 ppm 2,4-D + 10% CW; 1 ppm 2,4-D; 2 ppm 2,4-D; 3 ppm 2,4-D; 4 ppm 2,4-D in 4 replication. The results showed that the treatment of 4 ppm 2,4-D and 10% CW was the best treatment combination, resulting in an average callus size (1.4 cm), fresh weight (0.19 grams), dry weight (0.16 gram) and total flavonoid content (1.873 mgQE/g)
