Description
Summary:The Tungkal Composite of liberica coffee rejuvenation program at Jambi Province is urgently needed due to the latest status of the plants are old and showing diseased attacked. To support the rejuvenation, the provision of seedlings could be done by tissue culture approach through somatic embryogenesis. This research aimed to study the effect of 2,4-D, BA and TDZ on callus formation and embryo induction from liberica coffee leaf explants. Explants used were leaf sections with or without veins. Explants were grown on Murashige Skoog (MS) basal medium with 2,4-D + BA and 2,4-D + TDZ. A completely randomized design was employed in the trial, and each experimental unit was replicated three times. Results showed that callus could be formed on both types of explants, but leaf explants with veins could produce callus faster. The use of BA in medium could induce callus formation faster than TDZ. The higher the concentration of 2,4-D, BA and TDZ, the slower callus initiation. The addition of TDZ in the medium resulted in mostly callus, while callus from medium with BA showed a friable structure. Globular somatic embryos were formed in all treatments with varying amounts. TDZ can induce more globular somatic embryo than BA.
