The effects of sucrose, silver nitrate, plant growth regulators, and ammonium nitrate on microrhizome induction in perennially-cultivated ginger (Zingiber officinale Roscoe) from Hue, Vietnam
The number of research on ginger microrhizome production is low, despite
awareness of the drawbacks to the traditional method of cultivation and the
known health benefits associated with ginger essential oils. We examined
the effects of several factors on microrhizome induction in order to create a
production protocol for the cultivar found in Hue, Vietnam. To determine the
optimal conditions for ginger microrhizome production, different concentrations
of sucrose, plant growth regulators, ammonium nitrate, and silver nitrate were
investigated. Microrhizome fresh weight and diameter were increased to the
maximum values with application of BAP (6-benzyl amino purine), NAA (α-
naphthaleneacetic acid), IBA (indole-3-butyric acid), and a low ammonium
nitrate concentration, with 0.433 g at 9.03 mm, 0.437 g at 9.73 mm, 0.478 g at
10.80 mm, and 0.449 g at 9.53 mm, respectively. Additionally, we demonstrated
that kinetin has an inhibitory effect on microrhizome growth. The biggest
microrhizomes were grown on MS media containing the optimal concentrations
for each factor – 80 g/L sucrose, 1.9 mg/L AgNO3, 550 mg/L ammonium nitrate, 4
mg/L BAP, 6 mg/L NAA, and 4 mg/L IB
