The an annual herbaceous tropical plant which is one of the species of the genus Tacca from the Dioscoreaceae family is Tacca chantrieri. T. chantrieri has a unique inflorescence morphology like that of a bat. The people of Southeast China and Thailand have used by T. chantrieri rhizome as traditional medicine because the methanol extract contains secondary metabolites such as diarylheptanoids, pseudofurostan, withanolide, taccalonolide, and saponins. To maintain its sustainability, it is necessary to propagate T. chantrieri by using in vitro culture techniques such as callus culture. The purpose of this study was to determine the response of T. chantrieri leaf callus formation and to determine the optimal concentration with various concentrations of 2,4-D and BAP in vitro. This study used a completely randomized design consisting of control treatments, 1 and 2 mg L-1 2,4-D and concentrations of 0.5; 1.0; 1.5; 2.0 2,4-D combined with 3 mg L-1 BAP. The observations were made for 60 days after planting. The results showed that the concentration of 1.5 mg L-1 2,4-D + 3 mg L-1 BAP affected the percentage of live explants and the percentage of callus formation by 100% respectively, and the time of callus appeared 18.75 days after planting.

BA and 2,4-D combination were commonly used for in vitro culture of Shallot (Allium cepa L. var agregatum 2n = 2x = 16) to induce callus, but there was no information for callus induction on shallot seed (TSS) explant. Callus could be utilized for in vitro selection and generating of genetic variation. The aims of the research was to identify the response of TSS (Trisula and Tuk Tuk) as explant  and to obtain the optimum combination of BA and 2,4-D (mg.L-1): (0–0, 2–1, 2–2, 2–3, and 2–4) in callus induction. The research had been carried out in the Tissue Culture Laboratory, Faculty of Agriculture, Universitas Gadjah Mada during the year 2015-2016. Factorial treatments of variety and growth regulators were arranged in Completely Randomized Design with four replications. Data of percentage of germination, shoot height, root length, percentage of callus formation, callus weight, and chromosomes number of callus were recorded. The results showed that combination of 2 mg.L-1 BA + (1– 4) mg.L-1 2,4-D induced callus formation on TSS but inhibits shoots and roots growth. The best callus proliferation was at a concentration of 1 mg.L-1 2,4-D. Tetraploid callus chromosomes (2n = 4x = 32) was detected in Trisula grown in the 2 mg.L-1 BA + 4 mg.L-1 2,4-D, but in the Tuk Tuk callus did not detected the changing of chromosomes number.
