摘要

Axillary buds obtained from field grown plants of D. hamiltonii were used to initiate multiple shoots on Murashige and Skoog's medium (MS) supplemented with 2 mg L(-1) 6-benzyl aminopurine (BA) and 0.5 mg L(-1) indole-3-acetic acid (IAA). Profuse rooting was achieved when the actively growing shoots were cultured on MS medium supplemented with 1.0 mg l(-1) indole-3-butyric acid (IBA). Regenerated plants were grown successfully in the plains, in contrast to wild growth in high altitudes and rocky crevices of hilly regions. Roots of different sizes from one-year-old tissue culture raised field grown plants had the same profile of 2-hydroxy-4-methoxybenzaldehyde as that of wild plants. A maximum of 0.14% and 0.12% 2-hydroxy-4-methoxybenzaldehyde was produced in roots of one year old tissue culture derived plants and greenhouse grown plants respectively.
