Abstract
Aim: Turmeric (Curcuma longa L.) is a slow-to-reproduce perennial herb that is propagated from ground rhizomes. Despite its well-known medicinal and culinary uses, its supply for propagation is limited due to disease susceptibility and slow rhizome development.
Methodology: To optimize turmeric bud cluster development and determined appropriate concentrations of BAP (6-benzyl aminopurin) and NAA (α-naphthalene acetic acid) for enhancing shoot multiplication and rooting rates.
Results: The results indicated that MS (Murashige and Skoog, 1962) was basic media for turmeric; shoot clusters formation on media supplemented with 1 mg L-1BAP and 0.5 mg L-1 NAA; for shoot multiplication was 3 mg L-1 BAP and 0.5 mg L-1 NAA; and 0.5 mg L-1 NAA was favored for root induction
Conclusion: This research contributed to advancing our knowledge of valuable plants in Vietnam, particularly turmeric production on large-scale.
