Abstract Aim: This study aimed to access the rapid and improved propagation protocol production of Zamifolia plant using tissue culture.
Material and Methods: For callus formation and regeneration, two independent factorial experiments were carried out in a completely randomized design with 3 replications in the tissue culture laboratory of the National Research Institute of Flowers and Ornamental Plants in 2018. In the first experiment, to induce callogenesis, 2,4-D (0, 1, 2, and 4 mg/l) and BA (0, 1 and 2 mg/l) were used. In the second experiment, or regeneration of explants, NAA (0 and 0.5 mg/l) and BA (0, 0.5, and 1 mg/l) were applied.
Results: The results of the callogenesis experiment showed that a modified basal MS medium with concentration of 2 mg/l BA and 1 mg /l 2,4-D produced the best callus with 85% regeneration. At the regeneration stage of the callus, 0.5 mg/l BA and 0.5 mg NAA produced the highest number of seedlings and regenerated tubers (90%). Subsequently, single tuber seedlings were successfully adapted to 80%-90% in the cocopeat and perlite substrates.
Conclusion: The results were successful and could be possible to achieve the callogenesis and regeneration of Zamifolia plant with the formula presented and recommend as practical a protocol for commercial micropropagation of this valuable ornamental plant.
