摘要:Sari YP, Kusumawati E, Saleh C, Kustiawan W, Sukartingsih. 2018. Effect of sucrose on callogenesis and preliminary
secondary metabolic of different explant (Myrmecodia tuberosa). Nusantara Bioscience 10: 183-192. Myrmecodia tuberosa Jack is a
medicinal plant that contains bioactive compounds, such as flavonoids, tannins, tocopherols, phenols, and an abundance of minerals, that
are useful as antioxidants. With the constant increases in popularity of the medicinal plant, the M. tuberosa is threatened by extinction if
over-exploitation continues. Thus, the effort to conserve this plant is vital. Tissue culture is an alternative method to conserve and
produce active compounds that are similar to those of the native ant nest plant with callus. The addition of certain compounds such as
sucrose can affect the secondary metabolite content through in vitro plant or callus. The aim of this research was to find the explant
sources (cotyledon, stem, tuber, and root), determine the best growth regulator to produce the callus, and evaluate the optimum sucrose
concentration to enhance secondary metabolite production of the callus. The results showed that callus was obtained from all explant
sources and all growth regulators. The best callus that was marked by a friable green and yellowish green callus was provided by
cotyledon with the growth regulator of 2 mg⋅L
-1 of 2.4-dichlorophenoxyacetic acid (2.4-D) and 2 mg⋅L-1
of kinetin. Calli treated with
30 g of sucrose resulted in the best secondary metabolites, containing alkaloids, phenols, flavonoids, saponins, and steroids.
