Abstract
Liquid-cultivated compact callus aggregates (CCA) of Rhodiola sachalinensis were initiated from the explant of stems. Microscopic analysis showed that CCA displayed some level of cellular/tissue differentiation, which was perhaps responsible for the increased salidroside production. A higher ratio of cytokinin/auxin was found to be beneficial both for CCA growth and salidroside accumulation. Sucrose (> 100 g l-1) had a positive effect on salidroside synthesis, which was not due to an osmotic effect of the medium. The medium containing 40 g l-1 sucrose, 1.5 μM naphthaleneacetic acid and 15 μM 6-benzylaminopurine yielded ca. 120 mg l-1 salidroside after 24 days of culture.
