Abstract

Black ginger (Kaempferia parviflora), a medicinal herb native to Southeast Asia, faces propagation challenges due to slow germination and dormancy in seed rhizomes. This study investigated the efficacy of the cytokinin 6- Benzylaminopurine (BAP) in enhancing rhizome sprouting and early growth. Rhizomes were treated with BAP concentrations (0, 3, 5, 7, and 9 ppm) in a Randomized Complete Design (CRD) with four replications. Results demonstrated that 5 ppm BAP significantly reduced the time to bud emergence (13 days vs. 29 days in control), increased sprouting percentage (86% vs. 31%), and improved shoot proliferation (3 shoots/rhizome) and length (1.12 cm). Higher concentrations (7–9 ppm) showed diminishing returns, suggesting hormonal imbalance at supra-optimal levels. The findings highlight 5 ppm BAP as the optimal dose for synchronizing bud emergence and maximizing growth in black ginger, offering a practical solution to overcome dormancy and improve propagation efficiency. This study provides actionable insights for commercial cultivation, emphasizing the importance of precise PGR application.
