摘要：

Panax ginseng roots transformed by Agrobacterium rhizogenes grew rapidly in a hormone-free medium. The transformed roots showed biphasic growth: rapid during the first two weeks and slower thereafter. Sucrose in the medium was almost all converted to glucose and fructose during the first two weeks, and the root growth slowed down after the depletion of sucrose in the medium. Periodic changes of the medium maintained the high growth rate, and the dry weight increased by 31 times in 32 days, which is the highest growth rate so far reported for cultured tissues of ginseng. The medium exchange also increased the ginsenoside content in the roots. Effective scale-up of the root culture was achieved in a turbine-blade type bioreactor.
