Effects of different types of cytokinins on the percentage of explants responded to multiple shoots induction, number of days to shoot initiation, number of shoots per explant, shoot length, number of leaves per shoot, and number of roots per explant of ‘Bentong’ ginger after six weeks of culture.
| Cytokinin (µM) | Explant Responded to Shoot Induction (%) | Number of Days to Shoot Initiation | Number of Shoots/Explant | Shoots Length (cm) | Number of Leaves/Shoot | Number of Roots/Explant |

| Zeatin (10) | 100 | 6.87 ± 0.31 d | 4.07 ± 0.12 a | 3.71 ± 0.07 a | 2.90 ± 0.19 a | 9.43 ± 0.42 a |
| BAP (10) | 100 | 7.13 ± 0.39 cd | 3.53 ± 0.17 b | 3.51 ± 0.15 a | 2.45 ± 0.17 b | 7.43 ± 0.31 b |
| Kinetin (10) | 86.67 | 8.60 ± 0.27 b | 2.40 ± 0.19 c | 3.48 ± 0.35 a | 2.05 ± 0.12 b | 6.03 ± 0.37 b |

Values are means ± standard error (n = 30). Means followed by the same letters in each column are not significantly different at p < 0.05 using Duncan’s multiple range test (DMRT). BAP = 6-benzylaminopurine and TDZ = thidiazuron.
